300 Sherman Shortmag (SS)

RL26 will likely run the 215 the fastest, but again, not temp stable above 80 degrees. RL23 would work too

Thanks!

What are the C.O.A.L lengths looking like on the 300ss?

with the .110 FB chamber, the 215 is about 2.970 to the lands I think

well darn, I was pondering whether or not I could fit it into an AR10 platform

I'm about to start working on a new load with 215 gr Bergers in my 300 SS. I have some Ramshot Grand, which is a slow, probably too slow powder, but I started thinking that I might give it a try, being a ball powder. No load data anywhere that I've been able to find on it. Any thoughts on it?
