1. 50 cals (eventually all "sniper rifles" - anything .30 cal or over, then anything over .22, then any centerfire - you get the picture)
2. More restrictions on "assault weapons" (less and less mag cap, eventually all semi-auto rifles).
3. "pocket rockets" as defined by the moron legislator staffers (eventually all semi-auto handguns, then all centerfire handguns)
4. "junk guns" as defined by legislators(inexpensive guns).
5. One type of legislation which keeps rearing its ugly head, but probably is not in danger of passing, is banning all those evil handguns calibers that cause so much death and mayhem (bills that ban all handguns in .22, .32, .380, and 9MM (!!) calibers, naming the cartridges by name - ridiculous).
