RE: 7mm Rem. Mag. with Partitions
 

Oh ya, I' m also using Federal 215 Gold Match primers. I' ve had better luck with them than the standard Federal 215 M primers.

It should work OK, but I find IMR4831 to be just a " tad" on the fast side for heavy bullets in the 7 Mag. I prefer H4831, 7828, MRP, or RE22 in this large case. The 175-grain is certainlty NOT REQUIRED if you are using a tough bullet, the 160 is about as good, so use which ever one shoots best for you.:D

Thanks. I still have some RL-22 and some IMR 4850 left so I can try some loads with those powders as well to see if there is any difference.

Been WAY too hot around here this summer. Not much shooting time. I shoot 3 shots and my barrel gets super-heated and won' t cool down! Going to have to go late at night or real early in the morning I think.

i get 1 inch groups or better with 162 grain hornady spbt and i use the same rl-22 but i prefer to use cci primers and neck size also. i also set my bullet .002-.003 off the lands. good luck. that is the first load i ever tried and it did what i wanted it to so i stick with it.
