advice on a deer rifle for my son

[long450]

223 if legal in your state.

 

[Greyfox]

A 243 with a light bullet, good muzzle brake, pad and hearing protection. most 44 mag rifles I have shot have a miserable recoil with a 240 grainer. If legal, a 223 or 22-250 with a Nosler Partition. 6 might be too young for hunting.
