There is no way they would allow nor would it be possible to provide a powder that ate the barrel out of a weapon.
A little over the top.
We're not discussing that extreme, but whether this gunpowder causes throat erosion, alligatoring, or other damage. As for their frustration with internet experts, the Hodgon rep can get his panties unwadded, we're asking questions about plausible problems, not predicting problems, making claims, or spreading unfounded rumors.
I've talked to exactly one representative from a gunpowder company selling to reloaders that wasn't an asshole, and that is Pete Forras when he worked for Great Western at least a decade past.
Gunpowder companies, especially those that are resellers, do not have a lock on propellant and explosive expertise. Since I've started working on weapons, I've worked with 4 companies and three or four government offices that can all design propellants and explosives or modify existing products to produce custom profiles, do it quickly, and get it right. That doesn't make me an expert, and I don't claim anything of the sort, besides I have my hands full with my own expertise, but I know a few places to look for answers.
