Perhap you could send him go to some courses on hunting/stalking rather then long range sniper style. When using skills to gain closer access to what ever critter your attempting to kill you could buy him a 30-30 . the 30-30 utilizes a 30 caliber bullet and has a greatly reduced recoil. Believe...
Many believe the 270 will bounce off elk in the west. I think within 300 yards 270 would be somewhat acceptable if the wind is at your back while taking your shot. LoL
