My 11 year old wants to use his kimber Adirondack 300 black out on his cow hunt next month. I loaded some 120g tac tx bullets to 2250 and told him if he practices enough ill let him try it on a closer one.

My friend kilked a huge 7x8 bull with a 300 bo ar pistol and subsonic Hornady 190g sub xs. I was giving him crap about it he said it worked and then gave me crap about all the game I killed with arrows.

There's too many variables in the field to make blanket statements on what works and what doesn't you just have to know your equipments abilities and your own limitations in a given situation. Always helps to have a reliable bullet that will expand and penetrate a decent amount at the range you're firing it.
