Home Forums Reloading Big Game Rifles 150 grn long range accubond in a 7 mag.

Ok so far after shooting across chronograph IMR 4831 is giving the best speed out of h4831 ,7828,imr4831. I have a few rounds loaded with H1000 to try next. 4831 is giving me 3150 fps from a 26" barrel. Trying to get fps first then I will shot groups.
