Yeah, how about no. There are currently no good options (other than steel, which you want to ban below) that are cheap and decent for ammunition. Anything you go for currently will have a MUCH MUCH higher cost to it. The EPA would *love* to ban lead ammo, because it'd be a way to kill gun ownership. Do you want to make it harder for people to practice at a range?
Already restricted, actually. Except with M2AP, which currently cannot be regulated. It's such a non-issue though. No uses it to go out and kill people - not citizens anyway. Why restrict it when it's not the problem?
Two problems here. The first is that you must therefor kill hand loading and effectively make it harder to shoot as well - hand loading rounds is a way to get accurate rounds for much, much cheaper than match grade ammo costs.
Additionally, if you kill +P loadings that are sold, you kill the lethality. Hollow points can be stopped by layers of denim. +P loads are a way to deal with that as well as other issues - namely, handgun rounds aren't really that powerful. People survive 38 special wounds...and so people go with .357 magnum. Also, "+P" is just a naming. Who the hell is going to define what normal pressure is? The military defines it for things like 7.62 NATO and 5.56. But for things like 8mm Mauser or even things like 300 Winchester Magnum, it's a round the military doesn't use. Same for things like 41 magnum and 44 magnum. Who defines normal pressure? Right now, the SAAMI spec is just a list of loadings that are considered safe.
I plink with regular FMJ boxed 45ACP ammo. I test fire +P 45ACP hollow points when I want to be sure my aim is OK and I know how to handle it. I carry +P ammo when I have a gun on me. I'll keep my +P ammo, thank you very much.
Yeah, except people also flip over handgun open carry. Personally, I prefer concealed carry...and if you want to ban open carry, you need to FORCE all states to become SHALL ISSUE concealed pistol license states. Then I'm fine with banning open carry.
