The 338 Federal is a good round in the AR10 with better performance than the 308 and larger bullet up to 225 gr. I got my white tail yesterday with mine and what a hole it makes with the AE 170 GR soft point. It hit some brush first and a 2 inch entry hole and 6 inch exit hole while removing ribs, half the heart and liver while sucking half the stomach out the exit hole. The only damage to the stomach was from a rib puncture. No meat damage other than ribs.
