The muzzleloader would be fun to try, altough your range will be limited. But if you are use to bowhunting, then that is not an issue. I use 3 1/2" 4 shot win's in my mossberg 835. Try your 870 out with some 4, 5, and 6 and see how it shoots. I like win's, buddy likes fed, also been wanting to try some kent.
