I screwed up and got this 314-140 mold thinking 1300 fps would be stretching it, so went with the plain base. Now I am working with Mihec to get it in a gas check version. I had to go with PB checks which are more of a pain, and tend to flatten the nose some with the more pressure to seat them in HP version.
Just no way to get these numbers with the shorter cylinders in the single sevens and SP's or with shorter barrels, and the only reason I got this caliber was small game with the reduced loads in the 32 long brass, and step'n it up to reach out for vermin! I am very happy I went with the GP;s longer barrel and full lug heft.
