25-284 Powder Ideas

WOW. What was your COAL?

I have some loaded that I can measure, but with the ttsx, they just fit into the magazine, so under 3”. I’ll measure some and get back to you.

Eric…here what I was using and the COAL was just over 2.8”. If memory serves the 57.9 grains of H-4831SC was a bit over the book max so I’d start considerably below that and work up.

I know you don’t have R26. It’s the only powder I’ve shot out of my 25-284. It has a 25” Helix6 1-7.25” twist. I get 3150 FPS with the 131 BJ. I agree with others, that if it’s accurate I’d run it.

You guys are awesome!

@Corvalliscory, I have a 22” 1:7” barrel on my .257 WBY and propelling the 163 Chinchaga at 2915 FPS with H1000 during my pressure testing. I have Retumbo loaded for my next range opportunity.

Yes and I went through 3 barrels on my 28 and then 30 inch 30-378. US869. What's your point about barrel burners? I competed in 600 and 1000 yards

I do not have any issues with barrel burners. I am thankful for the experience, whatever round count I end up with.
