No, you don't need them but the 3 1/2" Mags. shoot the best patterns in my gun.Born2Hunt said:Do you really need 3.5 to shoot them close? They only weight 20-25 lbs. alive.
And this has what to do with the choke? That's an issue with the gun, not he choke...stack e'm high said:three of us use them and they are great but if your shooting a auto you might want to make sure if you shoot the hevi-shot that it ejects them and picks up the next one we had some problomes with them so now i went back to shooting winchester surppreum out of it and the pattern is still great
