With those actions and stocks.
I'd be thinking hunting rifles.
Pre 64s should be turned into big game hunting rifles.
A 270 WCF and a 375 H&H type of thing.
For plinking?
I'd pick up a PTG M700 with the bolt that has a small firing pin hole.And run a 6.5 x47, creed, or the straight up 260.
I know im spending your money.
But you asked..

Only accurate rifles are interesting.
