Barnaul 30-06 Ammo Draws Questions

MKS Supply offers the answer to the mysterious cartridge groove.

   Recently we received inquiries about Barnaul’s .308 Winchester and .30-06 hunting rounds. The .30-06 is an all American round once used by U.S. Forces as a military round but no longer. It is arguably one of the most popular and effective hunting rounds worldwide.

 

Note relief ring just above cartridge base.
The “mystery” is not really a mystery at all.

 

   The pressure generated by the .30-06 round is higher than other steel cased rounds the company makes. Steel cases are cheap to produce. However, since steel is much harder and less malleable than brass the overall steel case expands slower in the microsecond of gas expansion in the firearm’s chamber than brass cases.

   Engineers at Barnaul knew that to accommodate the higher pressure curve of the .30-06 round for that millisecond they needed to accommodate these higher pressures. So, they “simply” designed a slight round groove called a relief ring into the cartridge case near the base. The groove is roll pressed in, there is NO metal removal.

   Upon firing the additional pressure will be absorbed and reduced as the relief ring material is pressed out by the powder discharge basically duplicating the expansion of a brass case. Smart, simple, safe and well-engineered.

   Barnaul produces the .30-06 using strong polycoated steel cases for reduced cost. Some folks are afraid of steel cases.  Read the article linked here at Luckygunner.com ; in a bolt gun it would never cause the problems seen in semi-auto guns.  In short, reliability is as good as with  reloads.

   Barnaul is one of very few privately owned Russian ammunition companies who have been approved to supply their ammunition to the Russian Army. Their high standards and extreme quality control measures have also granted them the privilege to supply the Russian Special Forces with Barnaul’s high-quality ammunition.  Their ammo works incredibly well at an affordable price.

Miller Precision Arms 300MPA, SHOT Show 2014

We reported on this gun when Miller Precision first introduced it on July 4th,2012.  More recently they displayed the MPA300 at the SHOT Show, 2014.  At Media Day they had several rifles there ready for writers to test.

Miller Precision MPA300

Not too surprising, the writers all wanted to shoot the 300 Winchester in favor of the other models in 308 Winchester and 5.56 Nato.

The MPA300 has the distinction of being the only 300 Winchester Semi-auto on the market that is truly on the AR platform.  While the upper, lower, magazine and bolt carrier are specific to the MPA, the rest of the parts are all AR-10 interchangeable.   So you can dress your gun with any of the various features that are already on the market for the AR-10.

Media day turned out to be a real endurance test for the MPA300.  When Brandon Miller saw that everyone wanted to shoot the 300 Winchester almost exclusively, he decided to see how long the gun would run without a cleaning.  It went about 2700 rounds before the first malfunction.  A quick inspection and cleaning had the gun back at the line and by the time the smoke cleared the gun had fired over 4000 rounds without a second failure. 

Actions are machined from billet aluminum.  These guys are selling quality, not big-box store discount products.  Finishes for the Miller Precision guns are about as varied as you can ask for.  Among other things they offer hydrographic coatings, so the choices are almost limitless.  These guns are impressive.

Savage Offers New Model Axis II XP, Shot Show 2014

Axis XP

This new variation on the Axis XP features the AccuTrigger, which is adjustable from 2.5 to 6 pounds.  The rifle will come with a Weaver Kaspa scope mounted and bore sighted.  This is a 3-9×40 variable scope.

Barrels are 22 inches, matte blue on all metal surfaces.  The stock is a black molded synthetic.  A detachable five rounds magazine rounds out the package.  Eight calibers from 223 to 30-06 are offered.  MSRP is only $415

Axis barrels can be changed out just like the popular Savage 110 type barrels.  In fact our friends at 4D Reamer Rentals LTD. tell us that the barrels are interchangeable.  4D offers Savage pre-fit barrels in more calibers than any other maker we have found. So you can swap the barrel on one of these rifles and have the caliber of your dreams.

Rumor has it that 4D will be introducing a new barrel nut wrench, at the SHOT Show, for Savage smooth barrel nuts, like those found on the Axis series of rifles.

Finally, Savage is offering Youth models on the new Axis II XP series.  These rifles will have a 20″ barrel chambered for 243 Winchester.  Two camo patterns will be offered:  A woodland pattern and the very popular “Muddy Girl”.

Life is Too Short for Ugly Bolt Handles

Ugly Bolt HandleUgly Bolt handles are common on “sporterized” rifles from the 50’s, 60’s and 70’s.  Fewer gunsmiths forge bolt handles these days than they used to.  Forging is the process of heating and bending a military bolt handle to create something more like a commercial gun for sporting use might have. 

The main reason for forging a bolt handle is to make it work with a scope.  Military bolt handles are often straight or have a 90º downward bend.  This works fine for a military rifle with iron sights, not so great with a scope.

Once the bolt handle is forged into the new shape it must be filed and cleaned up to have an aesthetically pleasing look.  However, many hobby smiths or guys who are new to the business are not clear on how to do this work and make it look nice.

Some military bolt handles are a little short for forging.  A good gunsmith will notice this and will either weld in an extension to make the handle longer, or replace the handle with a better design.

There are several choices for bolt handles in the market place, some are easier to work with than others but they can all produce a nice functional handle with an attractive appearance.  Some require more shaping and forming than others.

Dakota bolt handles are the easiest I have found to work with and consistently get an attractive finished product with a reasonable amount of work.  They are available in 5 different styles.

  • 2 raised panelDakota Bolt Handles
  • 3 raised panel
  • Universal/Mauser
  • Winchester
  • Remington

Raised panel bolt handles are used by engravers or gunsmiths who want checker the knob of the bolt handle. The raised area makes it easier to checker the knob.

The Universal/Mauser handle is designed to weld onto the square root of a military bolt after the original handle has been cut off.  These are very popular and produce a nice looking finished product when the welds are cleaned up and all the lines are blended. 

Winchester style knobs emulate the pre-64 Winchester style bolt handle.  They have a large flat base that can be adapted to many types of bolts.

Remington style knobs have a base the can be silver soldered onto a Remington bolt to replace the factory knobs that many shooters would prefer to replace.  The styling of the knob on these handles is more round with a straight shaft, as apposed to the factory design which is oval and has a dog leg in the shaft.  These knobs are not checkered.

Mauser Bolt Handles Finished

All styles arrive “as cast”.  They are made from good quality steel that blues nicely when finished.  They can also be polished to a nice bright finish if that is your preference.

Jig for bolt welding

How to hold the bolt handle for welding. Notice the heat sink in the back of the bolt used to protect the threads during welding.

 

Since forged handles are often a little short the welded replacement also solves this problem.  Anyone practiced at both methods c

ould probably do either in the same amount of time, but the for my money the welded replacement just seems like less work for the result you get.

17 Winchester Super Magnum (Rim Fire)

This may be the only new cartridge at the 2013 SHOT Show.  Winchester’s new 17 caliber rim fire is an attempt to capitalize on the success of the 17 HMR.  I will be challenged on that point, so lets try and answer that challenge right here.  The 17 HMR has had reasonable success because it was intended to put 17 caliber cartridges in the hands of shooters without the need to reload.

17 Winchester Super Magnum

17 WSM (RF) vs 17 HMR

Obviously there are some center-fire cartridges in the marketplace that address these shooters as well.  The 17 Remington Fireball and the 17 Remington are substantially bigger cartridges.  Being center-fire generally means more expensive firearms too.

The advantage of rimfire is lower cost ammunition and lower cost firearms as well.  The only two models chambered for the new Winchester Super Magnum at SHOT Show in 2013 was one rifle from Savage Arms, and the model 1885 low wall from Winchester.

Winchester lists three loads for the new rim-fire cartridge.

  • S17W20, Polymer Tip, 20 gr. bullet, 3000 fps
  • S17W25, Polymer Tip, 25 gr. bullet, 2600 fps
  • X17W20, JHP, 20 gr. bullet, 3000 fps

At about 600 fps faster than the HMR the 17 WSM  has a about half the drop with the same bullet weight.  For more information see: http://winchesterproductdemos.winchester.com/17WinchesterSuperMagnum.html#/Home

Chiappa Firearms, Tell Me More…

Chiappa 1911-22Chiappa Firearm Company is an incredibly modern and progressive company operating out of Brusha, Italy. It employs high-tech types and old school traditional craftsmen to turn out a wide variety of high-quality firearms. Currently Chiappa makes over 70,000 firearms a year out of their new ultra-modern 108,000 square foot main plant which employs 80+ employees and exports to 62 countries world wide.

The company was started by Ezechiele “Oscar” Chiappa. In the early 1950s Oscar started in his career with Tanfoglio as a production line worker. But within four years at the ripe old age of 22 he was promoted to manager of all production which at that time was revolvers for the most part.

In 1958 the owner of Tanfoglio became ill and abruptly passed away; his wife decided to sell the company. In the process, Oscar was removed from his management position so he decide to resign and move on. His life-long love of firearms, along with his machining expertise, kept him in the industry.  He formed a new company to do subcontract work for other manufacturers. Eventually this new business lead to Oscar founding another company, Armi Sport.1887 Lever Shotgun

Armi Sport manufactured replica firearms such as black powder and early western models as used in America’s Wild West. These were and still are popular thanks to movies and television. And back then American westerns were very popular with Europeans. Eventually Oscar’s replica firearm business bled over into the huge U.S. market.

Oscar’s son Rino (pronounced Reeno) virtually grew up in the gun industry going to dad’s factory when possible. Rino learned early on how to make firearms at Armi Sport. By the age of 10 Rino was able to correctly operate most of the machines. Rino’s manufacturing education continued at the family business after hours, through high school and during summer vacation from school.

When Rino was around 19, that the old Tanfoglio Company that dad, Oscar worked in went bankrupt. This presented an opportunity to the Chiappa family to pick up more firearm orientated milling machines for their growing company. Rino pressed for the family to buy these machines–and to restructure the current Arim Sport. Imagine, the non-emotional and quiet family discussions these easy going Italians had around the dinner table… NOT.

In the mid-80s Rino took over management with dad Oscar watching to make sure he did not screw things up. But Rino had things well in hand and was growing the company and now granddad Oscar was teaching his young grandchildren how to make guns. In 2002, work was nearly completed on the new current super modern factory when Oscar took sick and passed away; he never saw the new factory completed later that year.

The company was growing very quickly and now with the name of Chiappa Firearms they expanded production further into modern firearms (some revolutionary like the Rhino Revolver). Production of their quality replica and blank firearms continued.

 Chiappa’s replica firearm unit reverse engineers vintage firearms and then using modern equipment creates accurate high-quality replicas. Chiappa machines all the parts and components from solid bar stock–no castings. All wood parts are hand oiled 3 to 4 times and hand polished. This is old country quality combined with modern day technology producing beautiful quality firearms.

1874 Sporting Deluxe

Rino is an active NRA member and he is not just a gun maker and designer; he is an avid hunter, shooter and President of SASS in Europe.
