Follow up on the blank chargers. I got the wood out without too much difficulty. Took about 10 minutes each. Started prying it out in little sections with a very small screwdriver. Once about half was out, the remaining piece usually came on in one big chunk. There was some slight tearing of the paper on the inside, like one layer of 20 separated but it doesn't appear to have weakened them. I may paint them with some glue just in case.

I would not take a chance to save a couple of bucks however. I won't do that again but as I now have at least five chargers and I hardly ever shoot, I should be fine for when the world as we know it comes to an end.
