Have a 1lb of Pyrodex RS that’s been on my shelf for years. I read is some old posts it rusts guns fast. I was thinking of just using it up for SxS shot shells at a local match where I can get home and clean within a few hours of being done. Does the corrosive crap get into a SXS SKB’s action? So let it sit on the shelf or use it up.
Thanks, JB
