You going to be looking at some long heavy Hammer bullets in that rig?
Maybe. Should shoot everything well and keep 400 grain mono solid penetrating straight as an arrow
Yep, i'd grab some 400gr CEB #13's and the appropriate Hemmer bullet and see what can be done, that's going to be a very hard slapper, my dinky 400 H&H powers 400gr CEB solids and A-Frames to 2400 fps with Varget, you can get a lot more done with your setup.
