My 7 x300wsm in a Rem 700 mountain rifle is a real shooter. Why don't you go to a lighter bullet? I shoot a barnes 140 TSX with great success. It will be crono'd on the 7 of Feb. It doesn't kick you into the middle of next week! 20 -30 rounds a day is not difficult. My longest kill has been 675 yds using the 120 XBT. Velocity is around 3150 est. in need of verification.
