Might just need to port the barrels. Muzzle lift might be the problem. Make sure you drill the holes back far enough so you can upgrade to screwing chokes later. I think putting a adjustable comb on the butt stock might be getting ahead of your self at this time. Morgan adjustable pads also help sometimes but I miss the fine looks of a white line recoil pad. And a wood butt stock with no pad just looks unfinished to my fine eye. wink
