How was the recoil with RL7 70gr & 350gr TSX?

I'm trying to set up a load similar to what you're trying to achieve in 450 Rigby & get 2500 fps or so with the 350gr TSX. Hendershots loads it to 2700 fps so 2500 fps should be easily attainable with the right powder.

I've had good luck with 108gr H-4350 & 500gr Swift A-Frames but the recoil is ferocious even with a brake.

I'm wanting to set up this load for a Brown Bear hunt (still researching outfitters). It may be worth giving Barnes or Hendershots a call or extrapolating data from 460 Wby in Barnes manual. I don't have Quickloads software but I'm betting it would be useful. Anyway, if I discover anything meaningful I'll pass it along.
