I'm looking at buying some of UMC's metal-cased ammo in .308. Do these folks use a good quality brass that can handle mutiple reloads? I don't reload, and don't know a thing about it, but I have an uncle who reloads and I intend to learn from him. I just want to make sure the first ammo I buy for my new .308 is decent for reloading. Thanks for any and all advice.

UMC is simply Remington's "bargain' priced ammo. The brass is made on the standard Remington tooling and is fine. WTS, Remington brass has a reputation for being soft. They tend to get dinged up by extractors and ejectors.

This ammo is not for CETME/HK delayed blowback guns. You will get separated cases stuck in the chamber.

As Robo says, UMC, "Union Metalic Cartridge", is a division of Remington as Western is for Winchester. Any of them as good as the other. The difference in factory ammo, small as it is, is largely in the bullets.

Fact is, Remington brass tends to be a tiny bit softer and thicker than Winchester-Western. Neither is "better", they are just a little different and it depends on what we want from it. Softer, thicker cases tend to last for more reloads while harder, thinner cases allow for more powder and tends to allow for a little more velocity. Most reloaders will never seem much difference.

How we size our cases and, to some extent, the tools we use for it, make more of a difference in how long our cases will last than the brand.
