I argued with a person on a blog recently a gun ban on AR-15 would not deter lunatics to use other rifles in a mass shooting if they couldn't get their hands on a AR-15 by chance. I told this person a killer could use a 30-30 or 30-06 and do similar damage that a AR15 would do. I said this on a basis this killer would walk down a crowded hallway or small classroom in a school. The person i was arguing with, said NO WAY a 30-30 or 30-06 could do what a ARE-15 could do. BUT I SAID, a 30-30 or ought 6 could do a lot of damage walking down a rather SHORT HALLWAY and SMALL CLASS ROOM. Would love to get some feed back from this forum that are very familar with using these other rifles i mentioned.
