was at a gunshow last week( although it was more military collectibles then guns) and there was dealer with all sorts of military ammo for sale. mostly .303, .308 and 7X57.he had .303 AP and tracer for $3.00 each so i bought a few of each.he also had something labeled ".303 observation" i was leery about buying some and decided not to because this is where our goofy laws hit a gray area. AP ammo is illegal in a handgun but legal in a rifle. API is banned. the law book listed WP and marking rounds as also being banned. the example it gave was the .303 Dewilde which is a white phospourus marking round. it also is called an observation cartridge.is this the same thing as what i saw?
i also learned another lesson. from the same guy i bought what i thought was a bag of 50 UMC rounds. turns out they where handloads that i couldn't hit a damn thing with, and least 5 of them wouldn't chamber. measured them when i got home and they are way over the max. OAL for a .303. never do that again.
