Found out a long time ago that the A-frame is the superior JHP with the discontinued Partition a close second... Been on board that "boat" since I first recovered one from a good size boar... Have Swift bullets in 357-41-44-45 and 50 calibers...I know a good thing when I can see the results at my feet and finding an expanded bullet does`ent hurt....just verifies
;\)

PS- what better way to prove to someone from Missouri that a particular JHP bullet works besides the dead animal it came from

Don`t know much about this but I do know jackets vary in how the copper is made... Swift and Speer bullets run slower then XTP from same gun with same handload... Whether the thickness also causes them to run slower I don`t know.... This sounds like something JWP may be able to answer...



Usually it is the friction increase of the jacket material that causes the same bullets to run slower than another bullet of the same weight. This can also because by bearing surface length.

A guided metal jacket generally creates Les friction than a pure copper.

John, like I told you man, you are a wealth of Relevant information in my book. We don't have to shoot the same guns and bullets to respect each other. I agree with you, it's the small details that make a big difference 👍
