make sure to check resizing of Top Brass reprocessed brass

[leadbury]

Bought a bag of 1x fired .308 mostly LC from top brass company.Was trimmed,polished,crimp reamed and resized. Checked sizing with rcbs case mic,it is .008 over"0".My M1a chamber is about .007 over "0'. This will not go in a Remington bolt gun chamber without further resizing so watch what your doing. Otherwise nice brass. This was probably fron an M60 machine gun that blows it out to .012-.014 from what I've seen. Tried to mention this to their tech rep,not available at time.

This holds true for any "processed" brass, no matter where it's purchased from. Sizing dies are different, and as you mentioned, a lot of .308/7.62x51 brass is fired through full auto firearms, where the headspace is adjustable.

I even size new virgin brass, as I've found some that wouldn't hold a bullet in .45 Colt, so I just make it a practice to check and size all brass I haven't processed myself.

Hope this helps.

Always resize as mentioned above. Starline even puts a card in their new brass saying exactly that.

Had a similar problem with LC 308 cases from Texas Brassworks. That stuff would chamber fine, but would not extract after firing. Took couple of batches of 50 rounds to figure out what was going on. After FL sizing, all was good again.

Still don't really understand what caused the cases to stick, but it's solved now.
