I think "high capacity" firearms are the main problem. What purpose is there for a semiautomatic rifle with huge clips, other than shooting lots of people? I think single bullet manual loading rifles are adequate for hunting. If you can't kill on the first shot, you didn't have a clear target or the skill needed. School shootings would be very different if shooters got disarmed and beaten to a pulp after firing a single shot. Or we could limit clips to five rounds, and make it highly illegal to buy more than one clip. That way the Holy 2nd Amendment is unmolested, and we do a lot alleviate the problem.
