Sierra Adds a 150 grain HPBT

150_264matchking

It’s a MatchKing® bullet actually introduced in October 2017 but is certainly being featured at the 2018 SHOT Show.  The popularity of 6.5 cartridges like the Creedmoor, 6.5×47 Lapua and 6.5×284 in all its numerous iterations will insure the sales of a new match bullet for Sierra.  At the time of this writing it appears Sierra is the only major bullet producer that offers a 150 grain bullet for the 6.5 bore.  This bullet will be best suited for cartridges with more case capacity, the 6.5-06 or the 6.5-284 will probably utilize it best.

MatchKing 6.5mm 150 grain HPBT (#1755).  Has a sleek 27 caliber elongated ogive and a final meplat reducing operation (pointing) to provide an increased ballistic coefficient (claiming over .700) for optimal wind resistance and velocity retention.  To ensure precise bullet to bore alignment, a unique bearing surface to ogive junction uses the same 1.5 degree angle commonly found in many match rifle chamber throats.  There is an interesting subject for a test; does matching the shape of the throat and bullet change the accuracy of any given bullet?

MatchKing® and Tipped MatchKing® bullets are not recommended for most hunting applications. Especially when we are talking about game animals of any size.  Match bullets are designed for accuracy and bucking wind over long range, but they are not designed to reliably expand.  Sierra makes GameKing® bullets for Hunters.

According to Sierra this bullet requires a barrel twist rate of 1 turn in 7.5” or faster.
