You are watching: What does umc mean in ammo


I have a TRS on order from CJ (who is great by the way). This is my first LB and first 1911. I am beginning to stock up on ammo for the break in and see good prices on Remington UMC mega packs (250 rounds) that .45 230gr Metal Case ammo. Does anyone have any experience with this ammo? Would it be fine to use during break in?Thanks.
Don"t know if it would be fine or not, but metal case is much harder than brass and more likely to cause damage. I do not use metal case ammo in any of my guns.
1 brass is metal, umc is brass cased, some are nickel plated.UMC is a reputable brand and perfectly adequate for range use.

duh, I read metal and interpreted steel case ammo:biglaugh:. IF it is brass, then there should be no problem. just becarefull about storing aluminum cased ammo in the east coast.
UMC is Brass cased, the MC (metal case) refers to the Bullet as in Full Metal Jacket.They just mark it MC instead of FMJ.Yes it is fine to use this for breakin and other purposes. I use it in my Baers with no issues.
There is some new Remington ammo that is steel cased with nickel plating. I have not shot any yet, but have heard that is good stuff.

Why will this rumor not die?Steel can be alloyed to be a whole lot softer than an extractor and a chamber. That"s what they do to steel used for cartridge cases. It will not damage your gun.
