Odd primer question

Hi everyone,

I have had 50 rounds of WWII-dated .303 AP rounds come into my possession. The cases are so deteriorated that I've pulled the bullets and removed the cordite. A couple of WWII British reenacting groups have expressed an interest in having a few, but I don't know of any way to render the primers inert short of firing them. Does anyone know of a way to chemically deactivate primers?

Thanks in advance!

A squirt of WD-40 or similar penetrating oil will kill them. Spray it inside the case and let them sit for a couple of days before you clean the oil out of them.

I've heard that but am still not sure. I once did that to a 7.62x39 round and then put the bullet back into the casing. Not only was it oiled, but it was sealed up with the oil. 10 or 12 years later I finally had a chance to fire the primer with an SKS. I pulled the bullet again and chambered it up, only to have it fire with as much snap as a new primer...I would actually fire the primers to make sure they're done.

Just me...but I would.

Thanks, guys. I appreciate the input.
