I'd like to replace the cheesy plastic OEM Winchester stock on the M70 308 I've had since I was a kid. I'd like to drop the money on a 5-700 dollar stock but I've got other guns and hobbies that require money. The B&C at $260 is about the max of my budget. How are these for an accurate hunting stock? I won't do any competitions with it, just some longer range hunting season practice... Hows the drop in fit? Are they easy enough to swap out or do they require fitting? Thanks!
