Finally got to try my .410 Mossberg Model 500 Turkey. It is a 2018 model with a 26 inch barrel and fixed full choke(.389). Set up HS Strut turkey head targets at 30 yards. With the factory double bead sight it hits right on POA/POI at 30 yards with the front bead just sitting on top of the middle bead. Federal Premium 13/16 oz. #9 TSS. Every target had in excess of 50+ hits in the head and neck. Really impressed compared to lead loads. I think I am ready for opening day. ;D I also tried Winchester XX Turkey 3/4 oz # 7 1/2 CP lead. Those are worthless in my gun. I will not buy any more. Probably end up using them for hunting cottontail rabbits.
I like using the 500 410. I have a mossberg 500 410ga TSS turkey gun. Mine has a Indian Creek. 385 choke. Using apex ninja 9.5 shot. Topped with a reflex red dot. I sure like the pattern it puts out at 40 yards.
