Pyrodex because of it's perchlorate roots is highly corrosive, much more so than real black powder. Perchlorates are also part of the problem with corrosive primers in surplus military centerfire ammo and if it will ruin a centerfire firearm, it will certainly do the same on your muzzleloader. So yes, it is undeniably an issue.
So from this thread I've observed that there is a segment of the muzzleloading community that say they use Pdex cuz they can't get real black anywhere but I'd bet a dollar that they are only looking in lgs or brick n mortar places. For reasons stated earlier, finding real black at a brick n mortar retail place is not going to happen. Real black is easily had online. Pool your order with a local reenactment group, join a NMLRA Charter Club or check into fireworks supply houses. Real black is available if you are serious about using it.
I won't use Pdex. Is it elitism? I don't think so since I've seen quite a few guns with ruined bores from using it and the owners believing the original hype surrounding it and I choose not to go down that path. If a sub must be used, I like T7 far better than Pdex. So make your choice.
