That is too good a title not to get a response, so here goes.
I will get some 450-gr Hammer bullets to replace my old 450-gr GSC HV,
should be great in the 1:20" twist CIP .500 Jeffery that I have been working on for the last 21 years.
Meantime I had .510-caliber rifles with 1:9", 1:10", 1:12", 1:15", and 1:24" with which to play.
For true varmint loads maybe sabots for .308/.50-cal ? I am on that too.
However, the 1:20" twist is probably ideal for the CEB 350-gr and Hammer 450-gr combo for varmints to big game.
