Mainehunt,

If you have a 243 why are you purchasing a 308? Unless you have a larger cal gun like 30-06, 300, 7mm, why buy a mid cart gun?

JMO-
if you start with a 243, I would jump to a 7mm or 300win. I shoot a 7mm with 139gr hornady SPs and it doesn' t kick much more than a my bros 308 but I can bump it up to 175gr for elk and knock em down at 300yards.

Just wondering.
