[ARCHIVED THREAD] - Machinegun Brass ?

Any concerns with reloading LC brass that was fired from a SAW?, I noticed brass for sale but it is a mix of M4 and SAW brass. I realize some of the SAW brass will be to damaged to use (bent in necks) but the ones that make it out in good shape are they ok?

Use a good lube and check sized cases in a case gauge.

My idea of good lube. Imperial is also good stuff. Clean off lube before trying in case gauge.

GTG, end of case below end of gauge, end of case above .002 cut.

If i remember right the problem was with the old M60s. I dont think there is a prob sizing m249 and m16 brass. At least ive never had a prob. with it being hard to size.

Last batch I got had real bad extraction marks and was very hard to size the first time around .

This is very much correct. In the 1980s and early 90s, most M60s Stateside had worn out barrels with (for reloading purposes) excessive headspace. The M249 has NEVER been a problem for "blown out" brass, though you do need to pay attention to case rims because extraction can be "robust" in the SAW. Like a lot of "facts" the old "machine gun brass sucks" rule was useful at one time, but not anymore.

Thankyou for all the replies

, I did resize some of the brass last nite, and some of the brass resized very easy and some a lot harder.

DRYFLASH3, thanks for those pics, I am going to invest in a case cage

You can also use a case gauge to "swage" the rim if it's a little deformed and keeping the case from gauging.

Will look like this.

Insert case backwards in gauge, wiggle it a little, then try again in the gauge.
