Powder for the 10MM

I use water dropped cast in all my glock pistols. Never had a problem with leading. I'm adding aluminum gas checks to the bases of the 10 MM PCed bullets because of the powder issues.
.40 S&W and 9MM rounds shoot lights out with WD slugs and Unique powder.

they are not recommended by glock.
hell lead aint recommended by no one since 1930 or thereabouts.

one of the earliest forms of rifling was a polygon barrel used in BP rifles, it was much easier to make than cutting rifling in a barrel and more consistent in both the actual twist rate and diameter so a custom mold didn't have to accompany each and every rifle.
somehow the whole system fell out of the attention of any major army's at the time.

My goto was HS-7, but I am about out of it. So, I have been working with Titegroup and WSF and H110. My loads vary depending upon the gun and what I want to achieve. I really like mid-level 10's in the EAA Witness platform and full house stuff in the 610's and over SAAMI in the MegaStars.

The deal with the Glocks was lead bullets we're supposed to Gunk up the rifling and cause excessive pressures. I use a harder lead, and have never had any kind of a problem with build up.

Undersized bullets, either initially or from seating in the tough 9mm or .40 brass, has caused serious but easily avoidable issues with Glock barrels in particular. More of an ignorance plus lack of proper attention to bore condition thing than a fundamental problem.

I don't own a 10mm, but would think that if Longshot worked well (aside from its almost un parallelled affinity for plastic coatings) True Blue would work even better. IDK if it is flash suppressed or will react with black poly powder, but it is superb stuff for magnum handgun loads. I would think Western would have mentioned True Blue in the email if it was flash suppressed.

Power Pistol will produce a fireball at night that has to be seen to be believed.

I held the .380 to 50 or so per session , once the copper was clear I don't get much more than antimony wash .
