IDMilton,

I have reloaded more than a few 7MM Rem Mag rounds. I use IMR 4350 almost exclusively. I've had excellent luck with it. Using my Sako Classic, I can easily get 3100+ FPS using 160 Partitions out of a 24" barrel. I can easily get better than 3200 FPS with 150 Ballistic Tips using the same powder. Neither of these loads showed signs of excessive pressure. Both are extremely accurate.

I have tried R22 with 160 Speer Hot Core bullets. I did manage to get better than 3200 FPS, but this load was nowhere as accurate as the Partition load. And it was a little too hot for my liking.

I reload primarily for accuracy. I am convinced game does not know a couple hundred FPS one way or the other.

I had a friend who used 63.5 grains of H4831 with 154 grain Hornady spire point bullets. It was a light 7MM Mag load. It did drop mule deer in their tracks.


Best of Luck,

R
