Re: Military surplus powder questions.
I was one who could not resist the low cost of pulldown powder, using the recommended start charge on the jug, I managed to ruin the bolt of my M1A with an overpressure situation. Either the jug was mislabeled or the mixed lot of propellant was FUBAR, either way it can be risky business. Yes many may chime in that it works fine, but my advice would be to stick to commercial powder, the savings is relatively small, especially if you and your equipment are subject to unecessary risk.
