K-31 Groups

I seem to recall that good 7.5 loads practically mimic known good 30-06 and 308 loads --in many cases, the same powder, same weight, and same bullet. In the case of 168SMKs, I think I read it was the same 42gr of H4895 I use in 308, conveniently enough :)

This is how 7.5 works its magic of matching 308/06 ballistics but at lower pressure
