RE: Rifle for kids
No I meant what caliber are you thinking of,technically speaking a 7mm-08 is 7mm caliber,a 308 & 30-06 ect is 30 caliber,I know its splitting hairs but i' ve been pulled up a couple of times on this forum for getting it wrong.
As to your choice of ammo,Federal premium 140 grain partition in 7mm-08 would be excellent for deer,dont overlook remington express with 140 grain core-lokt bullets,also excellent for deer.
Good to hear your son is comming around.
