You should still be able to punch them out with a good de-capper pin. They make a pocket swaging pin to take the crimp out and swage it back into diameter. You can avoid reaming the pocket.
Yes, absolutely doable. People just have to know, or they end up crushing the new primers going in.
But 115,000 rounds is too much for me to deprime. I am simply going to clean it up and sell it with the primers in it. I'm considering renting a cement mixer to polish them.
The brass is extremely dark, but not pitted with corrosion. I've found that a quick vinegar bath brightens them up, but I haven't found walnut shells too effective on taking off the rest. Does anyone have any suggestions for a better media? I've considered using fine sand in a cement mixer, but am worried that it will be too abrasive.
In any event, I would like to get them clean and packaged up in 1000 rd bags, so that I can start selling them for ~$50 per 1000.
