(2,621 posts)But a .300 AAC isn't.

Even though it is just a necked down .223. They use the same lower, same BCG, same magazine, just a different barrel (maybe a different gas block, I haven't built a .300 upper). The 7.62 X 39 (AK, SKS, AR) would be taxed, but not the 7.62 X 35mm (300 Blackout)
9 mm (the lung blower) should be taxed, but not 10 mm. Both of which are easily found in AR platforms, so could be covered under the "put the tax on ar-15 ammo too" umbrella. Although, the AR's in 9mm are not typically called -15's, but the ones in .22 lr are called 15-22's.
For the record, my all caliber was in response to an answer of " Bullets. n/t". Which I believe was confirmed by the reply of " Can a bullet in any chamber kill someone? Then, yes.". It wasn't "gaslighting", it was a RFI to a specific post.
As for no legitimate purpose for a .50 BMG, I don't know. I live in Florida (see the name), where deer (males) here weigh am average of 115lb. But I know that other game, in other states tend to be much larger, and have larger open spaces to hunt in. If I was going to research it, I certainly wouldn't think of using DU as a source.
