What makes ammo "junk" - Page 2

I've never had any problems with UMC ammo...that goes for .223, 9mm, .38 spl., 38 spl. +P, .357 mag. and .45 ACP.

As for junk ammo? I've tried Wolf, PMC, CCI, Magtech, Hornady, Federal, Winchester, Remington, Fiocchi...and I'm sure a few others that escape me at the moment. I have yet to fire any that I would call "JUNK". My only problem with certain ammo is excessive muzzle flash.

I've found Remington UMC ammo to be on a par with the other "economy" brands, like Winchester WB, Mag-Tech, PMC, etc. I've never had any issues with UMC, but others have, I've heard.

I can tell you there is one brand of factory remanufactured ammo, brand name Ultramax, that is junk. It goes bang, but where the bullet strikes is anybody's guess.

I have 500 rounds of UMC ,223 that I'm afraid to shoot. I recently saw a thread on AR15.com regarding concerns about this ammo damaging guns by overpressure caused by bullet setback. Just to see, I pulled one box (of 25) and inspected all the rounds. 4 of 20 had bullets that were loose enough to move back & forth in the crimp groove. One bullet is so loose that I can hold the case and turn the bullet with my fingers. Basically 20% failed my cursory inspection on one box. I haven't had the time to inspect the other 24 boxes. I have emailed the Mfgr with the lot number and am deciding whether to inspect all 500 rounds and return the defective ones, run all 500 through a crimp die, or dismantle them and reload them properly. I've used 9mm UMC and never had an issue.
