IMHO,Hands Down the best buy for the buck would be a Savage ML10II, use any of the subs with it including The original Substitute for Black powder. It is available with a thumb hole stock. Check Natches once again for some of the best prices.
I was just about to bring that up. If you like the Savage but don't care to shoot smokeless powder in it, don't. Just shoot BP or BP subs. It can shoot both.
