Re: 300 Win mag load advice

When the .300 Win. Mag. was popular in long range high power matches, IMR4350 gave the best accuracy with 190 through 220 grain Sierra HPMK's. While some other powders will shoot 'em out faster, I don't think the track record IMR4350 has can be beat for shooting 'em into the smallest cluster.

What's more important; smallest groups or largest muzzle velocity numbers?

Re: 300 Win mag load advice

I switched to BR2 Primer from fed mag and saw an increase in MV and decrease in SD I load 208GR Amax kissing the lands. Doing a ladder test this sat. 79 GR of h1000 showed great accuracy and at 81 gr I just started to flatten primers but didn't lose any accuracy.

After Saturday when I finish the ladder test I'll know which powder charger and bullet seating is optimal.

And catch from breast to breast the noble fire!
On valour's side the odds of combat lie,
The brave live glorious, or lamented die;" - Iliad, Book V
