Remington 100 gr. Corelock factory load. Example, my grandson shot his first deer last year. A dandy 8pt buck at about 80 yards with .243 Rem. Corelock. Deer was broadside at a slight angle. I recovered the bullet on the far side just under the skin. It weighed 67 grains. Buck went maybe 20 yards. One very happy lad.
In my 6MM I use handloaded Nosler 100 gr Partitions, always get an exit.
