How about a RRA in 458 socom, 2100 fps with a 300 gr bullet, max effective hunting range about 150 yds, recoils like a 243 win bolt gun, with 450 marlin terminal energy. also works well for bear and moose within its ranges.
I have a 20 barreled upper and it literally hammers deer.
RR
a 300 grain bullet at 2100 fps that sound about even with my muzzle loader and to say the least it kicks a hell of alot harder then a 243 bolt gun try more like a 300 win mag for comparison.
