I'm new on here and just looking for some advice or opinions. I have been shooting the same shotgun for the last five here during every dove, and turkey season. I am 5'2, 103 lbs and I shoot a Remington 1100. I have never had any trouble, injury, or anything other than a slight bruise on opening day of the season. This year I test shot 2 boxes of shells that morning because the gun had started hanging up and not kicking the shells out at the end of the season last year. Of course, it hung up with me and did not open at all the kick the shell out. I'm not sure why but it felt like a mule kicked me and was bruised and sore the following week. I hunted the day it happened and it did not seem like there was a serious problem Today I used the same shotgun (my dad fixed it), and was fine most of the day. I shot several times back to back almost straight up in the air. Within an hour I was in excruciating pain and could not even lift the shotgun or raise my are to drive home. Has anyone ever heard of a person damaging their shoulder with a shotgun? The recoil is not that bad on an 1100 and has never hurt me before. Could it be a positioning issue or a LOP issue? It has not been modified and I know the stock is a little to long.
