Dear Ganderite:
I am told you know quite a bit about these CBC surplus rounds. Tom told me I HAVE TO ASK YOU. Not to do anything till I contact Ganderite!
I just "won" (or was suckered) to buy two batches on the Switzers auction yesterday. One lot is 77 stamped, the other is from 1980.
I understand there was a mix up at CBC with pistol powder put in some rounds. Is it only specific to the 75 dated lots are should I treat all CBC surplus 7.62 as suspect.
Unfortunately I can only see posts from 3 years back on CGN, so don't have access to the older thread on this.
My plan was to dump the powder, use some some surplus powder (pulled from 8x63 Swedish ammo) that I have used in the past and is safe, and fire them off that way.
Is that what I should do, or is there a way to test to see if the LOTs themselves are safe and can be fired on their own.

Dear Dave;
You were wise to ask. Some CBA ammo surplus was loaded with pistol powder, and the bad rounds destroy rifles. Unfortunately the bad lot got re-mixed and re-packaged, so cannot be easily identified.
You will find that some CBC has nice neck crimps. And some has been obviously re-crimped. This is because some lots were improperly annealed, and the necks were too soft to take a good crimp. They took all this bad neck ammo and re-crimped and then repackaged. This is how the lot numbers got scrambled.
Back in the day I bought 1 or 2 hundred thousand rounds of this ammo and reloaded it all into very good ammo. I pulled the military bullets and substituted a Sierra match bullet, neck sized the necks without an expander and re-threw a powder charge. The ammo was excellent.
So far as I know, only the ’75 headstamp was a potential problem.
If you have 75 ammo, pull the bullets and save the powder. You need 2 powder buckets. Some rounds are extruded. Some are ball powder. The ball powder is the problem batch.
You can re-use the stick powder for any application where 4895 would work. Use 3031 data.
For the ball powder, save it all, give it a shake, and re-use it. That’s what I did for about 200,000 rounds. I mixed the powder in garbage cans. Re-load with H335 data.
