Remington Low Recoil Slugs shoot low right out of my 26" Versamax, removed the clamp and zero improved at 50 yards. The 7/8 oz low recoil Fiocchi's do very well. Has anyone noticed any issues running shotguns w/o a clamp for 3 gun? The guns take alot of abuse and the clamp provides extra support but seems to be at the cost of POI.
