I have just moved to NJ and I want to get into shotgun hunting but I need help. I purchased a mossberg 535 combo gun from dicks sporting goods because it seemed like a good gun for the money. The gun came with a 22inch barrel that has a choke that comes out of the end of the barrel that says "turkey lead only" and then it has a 28 inch barrel that came with 3 chokes (improved, full, and modified). what type of shot do i use with each barrel. i know that full choke is a tighter pattern that improved. i have 2 boxes of remington 3 1/2 #5 shot that my neighbor gave me. but which barrel and choke setup would i use to shoot slugs for say deer out of and are those good shells for turkey hunting
