I’ve been duck hunting 8-9 years now. I’ve tried Boss bismuth and yeah they work very well if your are shooting well but if you are missing all I see is dollar bills going down range.
I’ve been using the federal power shok or the Winchester superXs for most my years. Normally in 3” 2s for the whole season. I’ll up it to 3.5” 2s for divers in the late season and 3.5” BB for geese.
I mainly use patternmaster.
I know the Winchester SXP is a great gun and many people love their’s. I hated mine. I never got used to the Speed Pump and would short stroke it every time. I shot it a lot. Finally on opening day I missed on two separate wood ducks easy follow up shots. Due to short stroking I’d rechamber the empty shell. That day I took that shotgun, a pistol and a rifle to the gun shop and traded them off and threw more money in on a Winchester SX4 and never looked back. It was honestly the best thing I’ve done for my duck hunting career thus far.
