My 10 year old son just had a successful first deer hunt. Using my coyote rifle 22-250, loaded with BSB 64 gr. I'm glad you guys make a bullet on the heavy side for 1 in 14 twist. The load produced groups well inside an inch. He could easily hit soda cans at 100, even shooting from ground off his knee. After a hard 5 days of hunt he got a 100 yard shot at a nice 3 x 3 mule deer bedded down. He never got up.
