"...will need an M-1 Garand to start with..." It'd take major reworking to convert an M1 receiver to mag feeding. And a sizeable chunk of money.
"into a rifle very capable of taking every game animal on the North American continent." Any .30-06 will do that.
I have already worked out how to do it.
I am aiming for range. If I just want something that will drop any land animal, I'd just get a regular old M-14.
You would destroy an American Icon to make some silly sniper rifle.
If this was a mosin thread everyone would be screaming destroyer of history.
I would just get a m1a reciever because, as stated above, garands are not m-14s
I guess I am not winning your favor by saying this, but icons mean nothing to me. You are talking to someone who traded a Mauser Broombhandle for a CZ-52 and is still happy with the deal.
