Got a shoulder pointer and large hematoma from the steel butt plate of an old rifle this weekend. Half a softball where my collarbone used to be. The interwebs say I should be fine. Ice/sling for 72 hours and no shooting for up to three weeks. I don't shoot magnums anymore due to arthritis/loose AC joint, but this is a full on injury. Anyone else deal with these before? Will it occur more frequently after the first occurrence? I have enough trouble with my right shoulder and routinely shoot left handed as it is, but am not looking to make a permanent move to the wrong side.
