PMC Brass

Looking at some PMC 308, is the brass good to reload?

I’ve loaded a bunch of PMC 223 with no issues, I would expect anything different from their 308 but thought I would ask.

I have always had good luck with PMC brass. I would take the time to fill one with water and weigh it on a digital scale both full and empty to check the internal volume. If you have a Lake City M-80 brass you can compare it to so much the better. Or the brass used in a reloading manual. That will give you an idea if you are at a similar internal volume. If I remember correctly, I found PMC brass weighed slightly more and had slightly less internal volume, which meant more brass for strength but slightly higher pressures. Don’t depend on my recollection though, check it.

That’s a great idea to measure with the water.

I like PMC brass for reloading - what it was.  5.56 gets reloaded for 55gr 5.56 loads.  The .308 gets reloaded for 150gr .308 range loads.  No issues that way.  I tried using PMC Bronze 5.56 to convert to 300BLK brass, and the bases were bulged on the 3rd load of 300BLK. Stick in the die 8 times out of 10 on the 3rd load, so I threw the rest away that I'd cut and converted.  For BLK, after that, I only converted LC NATO 5.56 brass, or used real once-fired BLK brass. 

For sticking to the same cartridge, the PMC brass is still decent - I don't toss it, I do reload it.
