I have a Remington 870 with a 24" rifled barrel and simmons scope(12gauge). I use this gun solely for deer hunting. I have a leather tie down cheekpiece and Pachmyer rifle recoil pad on it. Gun's been cut down to my length of pull. Currently shooting a "low recoil" slug-Lightfield Hybred Lites 2 3/4". Still getting pounded. Any suggestions on how I can further reduce recoil. I was thinking of perhaps a mercury recoil reducer to put in the magazine tube...Any suggestions?
