Preferred Powder

[George Foster]

I was wondering what powder everyone likes for the 75HP bullets in the Win 243 and Rem 6mm.

I use H380 for pretty much every bullet weight in the .243, and for lightweight (55-75 grain) bullets in the 6mm.

I use H4350 for 100 grain bullets in both cartridges.

I have started using Superformance in a 6mm Remington. It has has been very fast and accurate. I have not used it yet in the 243 but would expect the same results.

Back 30 years ago in my 6mm Rem and Hornadys 75gr HP I used IMR 4064. It is also the load I made my longest shot on a running coyote of just under 400 yards DRT like it was struck by lighting.
It would shoot three shot groups under .75 inch at 100 yds.
