LC Match Brass

[Hinnerk]

I picked up some M72 match ammo cans at the flea market this weekend. One can was completely full of pulled down cartridge cases and there were a few in another. All primers were unfired. Very carefully, I deprimed all the cases and started to clean them up (none went off during depriming. Yay!). Attached are a couple pictures of a few pieces. Evidently these are NEVER fired brass.

Interestingly, there were quite a few of these cases with the flash hole noticeably off center. I found this surprising for 'match' ammo.

All the cases still have black 'asphaltum' in the necks where the projectiles were sealed. Any thoughts on removing that?

That's military brass for you. Not the greatest and will never compare to "match" brass like Lapua, Norma, etc.

Not a bad score though.

I've used GooGone to take the black crap off pull down 175gr bullets. After, I used alcohol to clean it off. I would suspect it would work on brass.

You can tumble it off.

unless your shooting for any kind of precision,I wouldn't worry about tar sealant residue.

This brass has been cleaned. By you? Also, are you the one who removed the Military crimp? Most likely this is fired brass. How many times? Who Knows?

Tar sealant that old can be removed with a Q tip soaked in acetone or any solvent you have available. Rule of thumb as to whether to remove the sealant is how old, thick or crusty is it. Being from 68 I'd most likely just remove it.

Check the length of the brass and also use a case gage to check to see if you need to resize the brass. You may have to only neck size this brass and should do so prior to using a case gage.

I've used never fired Primed LC Brass almost exclusively in my M1a Scout squad rifle and the brass never looked polished like in your photo. Also, why did you remove the primers? If this brass were never fired, the primers would be sealed in.

The brass was not stored well. There was some rust in the ammo cans, the brass was dark and had white 'corrosion' spots. Possibly none of the primers were still functional. I have nothing that uses 30-06 ammo so I'll either be reforming it into something that I do shoot or just storing it until I do (or find something else to do with it).

It is my understanding that LC Match cases had no crimp. Most primers pressed out quite easily. I had only one case that required more force than I was willing to apply. It is just my assumption that this brass was never fired. I figure that the tar sealant would be gone if the cases had been used repeatedly.

Yes, I gave the brass a citric acid wash and then tumbled with corncob/walnut mixed media.

That brass does not come crimped.

Easy way to get all the crud off the cases is to stainless tumble it. They will look like new after a couple hours.

Acetone for the sealant. Use an old bore swab/brush or Q-tip.
