Are you in N or NE IL? I may be in Rochelle, IL tomorrow. I don't want to sell off my supply, but could part with 100.
Another idea, Cabelas is showing Federal 209A primers in stock, $39.99 for 1k. They seem to work great, hot like CCIM primers. Maybe just buy them and sell any excess to local shooters?
Me, i just purchase what ever shotgun primer the store carries. Federal, CCI, Remington, Winchester, magnum, or standard, they all work. They all work.
