Beautiful SBT!
I shoot 1oz/1180-1200 fps for trap and find them nice and soft on the shoulder. Recently I tried some Rio Evo 24gm training loads. They have a published MV of 1360fps. I shot two boxes through my Perazzi TMS that wears a PFS stock. They barely moved the recoil reducer. I could feel maybe half the normal travel compared to a 1oz 1200fps load. Then I switched guns and ran two boxes through my Model 12 Pigeon Grade Trap and there was ZERO difference in felt recoil between it and my TMS. If you can get them in your area they may be worth trying in your SBT. They were extremely soft shooting and absolutely inkballed targets.
