I have a question about buck shot. I am wondering what is the tightest choke that you can safely shoot it with? It would be unplated lead fifteen pellet 00 buck shot 3". The gun is a Rem 870 Super Mag. I have heard all sorts of answers from folks I know, but none of them have an explaination of their answers. Some say cylinder, some say mod. some say you can shoot it with an extra full. My brother in law bought a cyote choke for his benelli nova. It holds a nice pattern with 00 buck at 80 yards. I want to use mine for the cyotes I see every year out on the pheasant hunt. Thanks in advance for any advice.
