I've shot just about every slug out there with a bunch of differant guns and barrels. The one thing I've learned is about every gun likes a differant slug. If you want to get the best patterns, buy a variety of slugs and shoot them, one will shine!

A couple things I've learned, typically 2 3/4" slugs tend to pattern better than 3" and several times the cheapest slugs pattern the best, why I don't know!

Good Luck!
