A "high firepower weapons ban"

[OneTenthofOnePercent]

115. Caliber category is a little wierd.

I think the caliber condition is a little convoluted. I didn't even know 10 gauge shotguns were a problem. Aren't the only 10 gauge shotguns like single shot or double barrel break action? Many handgun caliber hunting weapons (single shot thompson contender pistols and large game revolvers) are commonly chambered in calibers much larger than .44mag, sometimes even rifle calibers. I think the best way to deal with establishing a maximum caliber (in the interest of public safety, of course) is just a single size like .510 inches in diameter for rifled projectiles, 10 gauge for shotguns. It would be easy to understand and easy to enforce.

If you limit to 2 out of three - the intermediate caliber AKs and AR15 would never hit all three catgories. They are, in reality, intermediate in power (typically on the low side of power for atypical rifle cartridge). Some states don't even allow those calibers use for hunting due to low power possibly being inhumane.

Mechanically, there is no simple way to limit semi-automatic fire. A typical person can squeeze a trigger 2-5 times per second. Considering the simple 100+ year old .45acp 1911 with 7 round magazine, a very average 3.5 shots per second and a mediocre reload time of 3 seconds... you're looking at a maximum rate of fire of about 90 rounds per minute. Under the same conditions, a common 10 round pistol can about 110 rounds per minute. Basically, ANY mag-fed semiauto can EASILY surpass any reasonable limit on shots per minute assuming average shooting skills.
