The only 30 M1 carbine ammo that is corrosive that I have has a pinkish sealant for the primer. Only a handful of rounds that have been put up in a plastic freezer bag with a note inside as to it's contents. The French is so bad you can hear the barrel rusting and corroding. Not that bad but why shoot it when you don't have two. Which begs the question. With all of the M1 Carbines being re-imported from Ethiopia just what did they shoot in them?. Supposedly many were in good condition. The loose rounds were range pickups at the range so no box. Headstamps were just LC 52. Frank

Precisely.

I still have 350 rounds of the French stuff sitting around, and about 250 rounds of the Chinese-made LC52.

My solution to shooting this stuff has been to harvest the components and load the bullets and powder into Boxer-primed cases.

I then package up the corrosive-primed brass, mark it clearly as having corrosive primers, and leave it in the 'brass box' on my next trip to the local range. Perhaps there is SOMEONE out there who might not mind using the corrosive primed brass, but my shooter carbine is too nice. I don't want to anymore..

Exactly. I measure the charge every 5-10 cases and save the powder. I found they are consistently 9.7 gr of some weird looking spherical powder. I will just use the same powder, test it at 9.7 and see how they come out. Adjust as needed. I have probably 500+ rds of the stuff.....

Precisely.

My routine is to pull the bullet using a collet puller, and dump the powder directly into a primed case in my loading block.

The two types of brass involved when I reload these weigh pretty close to each other, so I am not all that concerned with case volume/pressure issues.

Every ten rounds or so, I rotate the turret on my press and seat the bullets.

It is probably just a bit slower than doing the powder measure thing, but for my purposes, it works just fine and there is no 'leftover' powder to worry about at the end of the day.

Just a reminder. The sealant on the bullets needs to be 'broken' before the bullets can be pulled from these cases, meaning that the bullets need to be seated just enough deeper into the case so you can feel the sealant 'crack'. If you seat too deep, the collet will not be able to get enough purchase on the bullet and you will need to use an inertia puller.

When the Chinese copy something, they copy everything, down to the markings! I remember a Chinese vendor displaying counterfeit automotive parts at the SEMA show. They copied the parts all the way down to the GM serial and casting numbers, which is what got them busted.

You have to be selective about this stuff.

Back when Rolls-Royce decided to put automatic transmissions in their cars, they received permission to copy what they felt was the best transmission on the market at the time, the GM Powerglide.

There were a couple internal surfaces inside the Powerglide transmission that were pretty rough-machined and did not 'meet RR's standards', so they took it upon themselves to machine those surfaces to a higher degree of 'smoothness' (RMS finish).

The resulting transmissions would not work properly. They went back to the original spec, and THOSE tramsmissions worked perfectly.

True Story.

OOPS!
