200 gr accubound retumbo 300 rum

[stxhunter]

finally got to load some rounds for my 300 ultra i started at 90 gr and work up to 95 in 1/2 gr increments shooting 5 shoot groups at 100yds 55 rounds total shoulders a little sore. Best group was at 94gr and 95gr with 95 giving me the best at a little under 3/4moa i'm sure someone with better from would close it up more. I'm pretty sure this is close to max if not allready there primers starting to flow a little and extracter marks can someone run this on quick load and see what the velocity might be . I'm shooting a 700p 26 inch barrel rem brass fed gm 215 primmers and retumbo at 94 gr and 95 gr temp was 84 today and i'm about 10ft above sealevel if that info is helpfull thanks in advsnce stxhunter

I would say your velocity is around 3150 to 3200fps.

Using 95 Grs. with the Fed 215 at 700 ft above sea level and 50 degrees in a 26 inch barrel I averaged 3225 with a 8 ES. Hope this helps.

what is your COAL? I can run quickload for you. The 300 rum with 200 gr 'should" max out around 3150 under sane pressures.

it was 3.72 this is the longest that would fit the mag
