So for now I'll start with 42.2 and 42.4 of H-4350 and see how that works. And if I run short of H-4350 I'll go with the IMR-4451
Thanks for the advice!
Start at 42.0 gr and go all the way up to 43.0 gr of H-4350. I had a particular lot, in a particular rifle that shot great at 42.8.
This goes back to just because someone's load works in their rifle, that doesn't mean it will in yours.
