You may need to knock the crimp out of the primer pocket, depending on whose military loaded the ammunition. This can be done with a primer pocket swager (I have an extra one from RCBS, BTW) You knock out the primer crimp and then use a primer pocket deburring tool. There are tools for doing this available from reloading companies. I bought an RCBS case prepping station, I must say, it works very well, a bit pricey (120 bucks) plus accessories, but a real good tool with a lot time saved. I also always recommend checking the brass for overall length.. especially if this is stuff you didn't shoot yourself. There are a lot of rifles out there that will stretch brass to the point where you need to trim it, but you will find that military brass generally tends to be a lot more robust than commercial stuff.
If I couldn't get Lake City M2, I'd rate Remington, Winchester and then Federal in the order of preferrence. Federal seems to be the most accurate (especially the Gold Medal) but oddly enough, the brass isn't that great when it comes to reloading!
Be safe!
