Get thee a Mosin 91/30 and feel the pain.....:lol:
As the saying goes it holds five but shoot an even number to reset your shoulder...:thumbs:
It has a kick...and a steel buttplate. But the ammo is even cheaper than a shotgun, the rifle is also cheaper.
You don't even have to put a bullet in it to stop a home invasion, the bayonet is 18 inches long and the whole thing can be used as a club.
Seriously. You should look into one. But as to the shotgun, keep it tight to shoulder, and squeeze. Don't worry about the bruising after a lot of rounds. Even the Mosin bruising goes away. :lol:
Set your feet lean a little into the shot but stay balanced and loose, use your upper body to take up the recoil. Stay squared to your target just act a little springy.
