I have three 7 RM rifles that I built and all shoot .5 or better with the 140 Sierra Pro Hunter and 66gr of IMR 4350. The rifles are a 700 action, a M70 classic switch barrel and a #3 *** converted to a #13, a 3 with #1 pieces and parts, floated barrel, etc. They all are running just over 3,100 FPS. I built an Argentine 98 Mauser with a Shaw barrel for a friend that helped clear my yard, 36 trees, after hurricane Ivan in 04, he would not take any money but had told me a year before he always wanted a belted mag, so I carefully built him the 7RM, with a custom exhibition glass beded wood stock from my personal blank collection turned on my duplicator and mounted a $1k scope on it. When I finished it I gave him 100 of the 140 loads in an MTM box. In front of 8 witnesses he shot a .198 inch 5 shot group at 100 with that rifle. He and that Shaw barrel could shoot. He died 7 months later of small cell lung cancer.

RT. You shouldn't really need a second shot, but if you do, load some shorter bullets that will feed. I usually use Barnes bullets for my follow up shots, in case of bears. I like the 168 gr. Bergers so much, I've used them for javelina, deer, Barbary sheep, and elk. They do the same thing to all of them: DRT.
