I shot my Remington 870 12 gauge for the first time ever with 2 3/4 1 ounce slugs out of a 18 inch barrel I shot 10 slugs.That was all I had but 50 would be my limit the recoil was like getting punched in the shoulder by a big goon even though I held it right and leaned into the shot with one foot out I feel sore in the shoulder.But I was accurate with it at 30 feet I put perfect groupings with it.It was a fun gun to shoot though even though the recoil was more than I thought and ever experienced.I handled the recoil well but it kicked hard enough for my shoulder to be sore after only 10 slugs.
