Obama Thinks it’s All About Him!

ABC News’ Ed O’Keefe Reports: The Obama campaign is taking issue with a comment President Bush made while speaking to the Knesset on the 60th anniversary of Israel’s statehood.

“Some seem to believe we should negotiate with terrorists and radicals, as if some ingenious argument will persuade them they have been wrong all along,” the President said to the country’s legislative body, “We have heard this foolish delusion before. As Nazi tanks crossed into Poland in 1939, an American senator declared: ‘Lord, if only I could have talked to Hitler, all of this might have been avoided.’ We have an obligation to call this what it is –- the false comfort of appeasement, which has been repeatedly discredited by history.”

Senator Obama seems to think that everything is about him!  I guess he did not hear about Jimmy Carter’s distasteful and anti-American act of meeting in April of 2008 with the leader of Hamas. Israeli Prime Minister Ehud Olmert did not meet Carter during his visit to Israel and Washington criticized him for his contacts with Hamas, which both regard as a terrorist group.  It would be much more impressive if the Senator called for Jimmy Carters passport to be revoked for his actions.

Rifle Accuracy, Sub MOA Requirements

Action tuning (blueprinting) is the process of making all the parts that make up the action square and true to the bore. First the locking lugs of the bolt must be lapped to insure even solid contact with the locking surfaces in the receiver. When finished the lugs should have equal contact area and contact should exceed 80%. This is accomplished using professional lapping compounds which produce smooth even surfaces.  Finally we put the action recoil lugon a precision mandrel and turn it in the lathe to face the front of the receiver square to the bore.  Note the areas in the picture that are pointed out, the light spots are where the metal was in full contact during bluing, the dark areas were exposed to the bluing salts, obviously contact was not even.

Barrel Lapping is available for new barrels upon request.   Lapping the bore can offer more uniformity, velocity, and accuracy. This process removes the small burrs and marks left in the bore from the machine process. It also polishes the bore, which reduces fouling. A side benefit is that, there is little or no break in for a lapped bore. Which saves lots of time, money, and tedious cleaning.  Many of the best barrels are lapped by the manufacturer, McGowenHart and Lilja are three examples.  

Barrel Fit is the next consideration. The barrel must be set up on the lathe so that it is centered perfectly on the bore. Centering the barrel on the bore insures that it will be mounted squarely in the action. The shoulder will be exactly 90 degrees to the bore and the threads will be concentric to the bore, all essential to accuracy. Equally as important is the crown. It also must be concentric to give best accuracy. Over the years we have tried many styles of crowns at many different angles to the bore. Some work better than others but the bottom line is always the same, if it is concentric it will be accurate. 

Trigger Jobs can do more for accuracy than you might think. These days the factories are shipping guns with trigger pulls of five to eight pounds. To add insult to injury they include lots of sear engagement  (shooters call that ‘Creep’).   A trigger job will minimize sear engagement and bring the pull to a consistent weight that will give the shooter better control over the moment of ignition.

Bedding methods varies a little from one action to the next. The best method on average is to free float the barrel and bed the action. This can be accomplished through either pillar bedding and glass bedding. Pillars are made from metal usually aluminum, the purpose is to add a support to the stock so that it cannot be crushed by the action screws. The pillars also add stability to the bedding job. Glass bedding is the most common method used. Fiberglass and epoxy are used to bed the action of the rifle. This adds stability and protection from humidity. Proper bedding requires an understanding of the pressure points of the action and the methods that will provide the best support and results. A good bedding job will improve accuracy.

Ammunition is a major factor in accuracy for any rifle.  Accurate ammunition is a product of good reloading skills and tools. There are many makers of reloading dies. Quality varies widely from one manufacturer to the next. All will work to produce usable ammunition. Accurate ammo requires better quality dies. Just like the rifle, the dies must be concentric in order to be accurate.  Think of it this way, if you were to draw a 12 inch long line on a piece of paper with a ruler held firmly down you will get a single clean line from end to end. What happens if you stop every inch and pick the ruler up, replace it on the paper, and continue the line? Likely no matter how careful you are the line will not be perfectly straight. When we reload ammo we are picking up the ruler with every component used and with every process executed.  That is why its so important to make sure everythint is just right when loading for accuracy.

This is by no means a complete discussion of rifle accuracy but its a good start.  I recommend that you take your reloading manuals down off the shelf and read some of the articles that they contain.  You will be amazed how much good advice on how to load the best possible ammo is already on your shelf.

Political Question!

If Barack Obama were to win the Presidential Election in 2008, would that make the United States an Obamanation?

Renting Reamers, a great way to save money.

One thing never changes, the cost of doing business goes up.

Renting chamber reamers is one way we hold costs down for our clients.  WWW.4-DProducts.com provides some of the reamers I use for custom jobs.  It just does not pay to buy every reamer, many of the reamers I own have only cut the chamber they were bought for.  Then they just lay there in the drawer. 

4D provides me with reamers that are SAAMI spec, and in good sharp condition.  If you think about it they can’t afford to send out a dull reamer, who would rent from them a second time, and like all businesses it’s repeat clients that pay the bills.  Best of all by using such a service you can chamber for hundreds of calibers with minimal expense.  Whether your a hobby gunsmith or a professional, having access to a large number of calibers is pretty cool.

When you custom order a reamer it will normally take 4 to 6 weeks to arrive, rentals are normally in the shop within a week.  Just one more way to save money and offer more. 

Keep your powder dry!

“Diplock’s Syndrome” or Why are Gunsmiths Grumpy?

 “Diplock’s Syndrome,  a syndrome contracted by gunsmiths.  The cause is close contact with clients or customers who lack patience.  Custom guns are hand made and require a great many hours of work and attention from a highly trained professional.  Researchers have found that even the most patient and easy going gunsmith will loose his sense of humor and become an old curmudgeon as a result of contracting Diplock’s Syndrome.  Contributing factors appear to be phone calls, faxes, letters, and emails asking, “Can you give me an update?” or “How is my project coming along?”  The reason such simple questions inflame a case of “Diplock’s Syndrome” seems to be that each client thinks he is the only one making that inquiry when in reality he is among many.

If you would like to spare your gunsmith the crippling effects of “Diplock’s Syndrome” the best thing you can do as a client is remember that gunsmiths do not make a living by storing guns.  They perform custom services that require time.  Remember that delivery times are estimated.  Patience will help you to receive the best possible quality of work, and your gunsmith will be much more pleasant to deal with.

In an article by Samuel Clark Jr. originally published in “Twenty-two Caliber Varmint Rifles” by Charles Landis, 1945, Clark tells a story about shooting accurate rifles and the good natured jabbing and poking that will inevitably erupt among shooting buddies.  Here is an excerpt: 

“The writer (Clark) had often remarked how frequently it is that we read of rifles capable of shooting into a minute of angle or  how often we hear of ¾” or even ½” groups shot from rest or a machine rest at 100 yards, or 2” or less than 2” groups at 200 yards.  It has also been frequently noted that although shooting, as just described, causes no great stir among the shooting fraternity, nevertheless, such shooting even in the hands of well-known experimenters, equipped with the most accurate rifles obtainable, has not been the rule on the range described above—in fact far from it—actually, quite the contrary, and  if all groups fired by each individual shooter were averaged, the result would indicate the progress along the lines of accuracy was a very dubious matter indeed.

         Among visitors to the range who had not neglected to observe this point, was Clark’s good friend and genial shooting companion, John Diplock.  In fact, Diplock had so often been disappointed when rifles which were described as tack drivers failed to shoot in the vicinity of the tack, let alone shooting group after group measuring 1” or under, that he had lost a great deal of faith in the expressed opinions of his fellow man. 

         Another illusion, which Diplock had learned to discount about 99%, was that of the dependence that could be placed in the 5-shot groups as a test of accuracy.  The whole matter had been discussed from all possible angles and the opinion was firmly held that a group of 10 shots fired from any rifle from bench or machine rest at 100 yards, which measured 1” from center to center of bullet holes farthest apart, was still a mighty fine group, and despite claims to the contrary, that the rifle and rifleman, who could sit down and do such shooting when the chips were down, with spectators present, and continue to do it for 10 shot group after 10 shot group, just had not come along yet. 

               Diplock, sensing an opportunity to turn the weekend into a payday, pounded his fist on the loading bench and stated that he had listened to all this 1” talk he wanted to, and he had seen all the selected groups he wanted to see, but what he did want to see was a shooter who was man enough to demonstrate before witnesses and with money on the board, what he could do about this 1” business…  Peeling a big bill off his roll, Diplock laid it on the loading bench and announced that he had “had his say.”” 

           Why repeat all this here?  Well, for years gunsmith’s have had the reputation of being grumpy, opinionated, old duffers.  It is the author’s contention that the story above is a good explanation for the attitudes displayed by many long time gunsmiths.  Professional gunsmiths are forced to endure amazing tales of accuracy, and hunting prowess, most of which no 5 year old would believe.  After some exposure to such comments, stories, statements, anecdotes, yarns, legends, and/or outright lies even the kindest heart will become hardened to these tales.  This hardened condition the author has dubbed Diplock’s Syndrome.

By the way, Diplock lost his bet… nobody is perfect.   FDZ

Grizzlies possibly being delisted.

 

The District Court in Montana granted Safari Club International’s request to intervene and represent hunters in a second lawsuit challenging the Endangered Species Act delisting of the grizzly bears of the Yellowstone area.  The delisting turns over management of this recovered species to the states of Idaho, Montana, and Wyoming.  SCI supports state management as more responsive to the needs of sportsmen and women, who often have negative encounters with grizzlies while pursuing recreational activities.  In briefing currently set to begin on June 1, 2008, SCI will argue, among other things, that the Yellowstone grizzlies long ago surpassed recovery goals.  SCI is also participating in grizzly delisting litigation in District Court in Idaho.

Another reason not to live in Chicago!

BELLEVUE, WA – Anti-gun Chicago Mayor Richard Daley has taken one more step toward turning his city into a police state by planning to give police fully automatic M4 carbines, while still fighting to block the gun rights of citizens not only in Chicago but throughout Illinois, the Citizens Committee for the Right to Keep and Bear Arms said today.

“Here’s one of the most anti-gun mayors in the nation, who has been trying to ban common semiautomatic rifles for years, but now he’s rushing to turn his police into a paramilitary force doing battle against street gangs and other criminals,” said CCRKBA Chairman Alan Gottlieb, co-author of America Fights Back: Armed Self-Defense in a Violent Age. “Yet this guy works overtime to make it impossible for average citizens to protect themselves against the same criminal element.

“If Daley thinks turning Chicago neighborhoods into gulags, where only police have guns, is going to keep people safe,” he asked, “he is horribly mistaken. They tried it in Washington, D.C. and it’s been a disaster!

“Daley has decried the violence in Chicago,” Gottlieb said, “but the mayor seems to ignore the likelihood that it is his own urban policies that have made the Windy City so dangerous. The good citizens of Chicago deserve the chance to fight back and make a difference. Instead, Daley sends lobbyists to Springfield to erode the gun rights of Chicago residents and all Illinois citizens, leaving them first defenseless, and now likely to be caught in a crossfire.”

Daley’s effort has attracted the attention of Catholic priest Michael Pfleger, the man who tried to incite a crowd last year outside of Chuck’s Gun Shop in suburban Riverdale to “snuff” proprietor John Riggio and any politician who stands in the way of Pfleger’s gun control agenda.

“When Daley’s solution to violence involves crackpots like Pfleger,” Gottlieb noted, “the city is in trouble, and not just from criminals. It is time for a new approach, not one that turns police into an army of occupation, but one in which citizens can defend themselves and their families, without demagogues like Daley standing in their way.”

Improved Pistol Accuracy!

Had an email from a client not long ago bragging about how he improved the accuracy in two of his revolvers.  Actually what he did is a simple procedure that really does help.  He reamed all the chamber throats in his cylinders to the same dimensions. 

Believe it or not, the factories are in too big a hurry in most cases to make all the chambers the same.  This is probably one of the biggest causes of accuracy issues with a revolver.  Cylinder Throating tools are made by Manson reamers, they come with several bushings so you can match up to each chamber throat when reaming.  My client said he used nearly every bushing by the time he finished his two cylinders.  Below are som photos that illustrate what he did.Shows how he kept track of what bushings were needed.Demonstrates how all throats are now the same.

He reported that before this job the guns shot between 2 and 4 inch groups @ 50 feet.  They now shoot much better, click here for a pdf of his targets.

He rented the tools from 4D Reamer Rentals, I check they have them in 357 and 45 caliber, they tell me they will add the 44 caliber tools as soon a client orders them.  All in all a pretty cheap way to get more out of your pistols.

Barrels with Chrome lining?!

Manufacturers are doing something relatively new, they are putting a chrome wash in the bores of some barrels.  It appears that they are in magnum calibers mainly.   Before USRAC (Winchester) shut down they were doing this with the WSM barrels.  It appears that Browning is doing the same thing.

Latest gun gossip is that the New FN bores are chrome washed.  Also the new “Winchester Repeating Arms” do to come on the market this summer some time will be using the same process in some of their barrels. 

Why is this important?

Because if your not aware of it your reamers will take beating.  One reamer maker told me that he is selling carbide throating reamers regularly now, he said that was unheard of just a couple of years ago.  Reamer rental agencies are aware of this problem as well and will be forced to resharpen reamers used in chrome bores, be prepared to pay for the resharp if you make this mistake.

The worst part of this little bit of information is that there is no clear list of calibers or models in which the manufacturers are using chrome.

Keep your powder dry!

4D Reamer Rentals tells me that they are researching the problem and plan to add a page to their web site to help inform clients.

A Question I answer a lot!

Can you rechamber my NEF or TC Encore…?

The real question often should be can my 308 barrel be rechamber to 338-06?  Or some 30-06 Ackley Improved etc. 

First when you thinking about rechambering a barrel the bore diameter must be the same unless you are willing to rebore the barrel as well.  Reboring is often thought of as a cheap alternative to a new barrel.  It is usually less expensive but the best reason for a rebore is when you have a gun that has some intrinsic value, either a family gun, or maybe a fancy barrel that has a quarter rib, custom sights, octagon, etc, that would be expensive to duplicate.  Such barrels make sense to rebore.

Back to plane old rechambering… Just look at it this way, you must pick a chamber that is larger than the original chamber, ideally, larger in diameter and at least a little longer.  Sometimes the original neck diameter was on the large size and when you rechamber it leaves a small groove or mark in the neck area of the chamber.  Normally this is not a problem for function, but it leaves marks on your brass and might hinder accuracy.

Ackley Improved cartridge do now work well for single shot rechambers unless your starting from a much smaller case, like a 22 Hornet to a 22-250 AI.  Now if you working with rimmed cases then an Ackley design is fine in a single shot simply because the rim handles headspace.  Rimless cases headspace on the shoulder and Ackley rimless cases are .004″ shorter than the factory counterpart.

Anyway, single shots make for a fun and cheap way to try new calibers.  Give it a try.
