Just installed, adjusted and burned about 50 rounds thru it. Ran everything from the Federal 7 1/2 load to Remington Slugger 2 3/4 Rifled Slugs perfectly. It also greatly reduced the recoil of my overgased monster to a decent level. 50 rounds and my shoulder isn't bruised, I couldn't run 10 rounds before and say that. Think I'm in love, thanks for the help and the awesome product!
