Howdy BCB,
You mentioned yesterday in Post No. 37 that you experienced corrosion in your RCBS powder measure when throwing charges of surplus 860 and 872.
I'm wondering if you or other readers have experienced any other unusual corrosion associated with the use of those two surplus powders?
I ask the question since some time ago I had some mysterious bore corrosion occur for reasons still unknown to me. At the time, I was shooting some compressed loads with WC 872, along with many other loads (uncompressed) with other various powders.
The bores of a couple of my rifles developed a light, "hairy" coating of red-brown rust. The rifles cleaned up fine, so I guess I spotted the trouble before it caused any pitting, but I never really pin-pointed the source of the corrosion.
Might there be some corrosive component in surplus WC 872? Please let me know if you've encountered any similar occurrence of corrosion using surplus propellents.
Thanks, and happy trails,
