Some of them off-brand guns need special ammo to work well. Especially when you get into those self-loaders, heh. Make sure it don't wrap around your head as you fire it.
And on the Arizona ammo front: bud who travels into Snowflake for his weekly stimulation and cash depletion, said he saw today a pickup parked in front of a beauty shop. Tailgate down, various cases of ammo visible from the road, and a father figure selling boxes out of cases. The seller's kids were waving "AMMO" signs. Real fine thing there all around: seller gets some cash, and his kids likely learned much also about how a father deals with people (good or bad, I dunno.)
