HB 21 is currently in committee(latest of several), I can't say if it's likely to pass or not, but it's not in committee hell(since it's making headway) so it has a chance. SB 28 is currently plowing through and is very likely to pass in the 2010 session.
Both make exceptions for Fully Automatic arms, exploding ammunition, smokeless cartridge arms with bores over 1.5" and non-man portable arms. So sadly, I still can't have full auto
However, it DOES cover:
Short barreled rifles
Short barreled shotguns
Silencers
Smokeless(gun powder)* cartridge guns(firearms)** with bores under 1.5"
Black Powder cartridge guns** of any bore diameter
Open bolt semi-automatic firearms
Firearms kits built with "Made In Florida" receivers on imported parts
In addition, it protects currently legal things which may be banned on the federal level in the future such as:
Flash hiders
Large capacity magazines
Any and all currently legal firearms accessories such as lights, lasers, optics, bayonets, etc.
All firearms, including so-called "assault weapons"
Kit builds
* - Smokeless powder is common gun powder. Also called nitrocellulose or double base nitrocellulose. The name "smokeless" comes from it's early history, as it produces considerably less smoke than black powder(which is an entirely different chemical compound). In the case of this bill, it means that firearms using smokeless powder are limited in caliber to 1.5"(1.50 caliber, 37.5mm), while black powder arms are UNLIMITED in bore diameter.
** - The bill only covers guns that use "single piece ammunition", that is the bullet, primer and powder contained in a cartridge. Two part or non-cartridge arms such as muzzle loaders, muskets, cap and ball revolvers, etc. are not considered firearms under Federal law and are EXEMPT from all federal firearms laws anyway.
