i used only 70 grains due to my upper shoulder being boney and my rifle buttplate slopes a little to much and hits bone. Now that 385 grain grea plains bullet i used this muzzleloading season in my inline, i shot a doe at roughtly 90 yards, hit high, dropped her and i shot her again this time at 25 yards with 90 grains pyrodex rs and that 385 grain bullet, it went throught the first shoulder " dead center" and hardly made a scratch on the other shoulder. i figured that huge bullet at close range would have blasted all the way through. I've gone back to powerbelts due to them letting me shoot flatter and longer ranges. Plus ive always had great luck with them putting the deer down.
