I assume the powder is fully cured. The powder was tumble coated in a cool whip tub and cooked at 400 deg. for twenty minutes in a preheated, stand alone, three rack, small convection oven purchased at a garage sale.
I used an oven thermometer to set the heat setting on the dial.
The PC is hard as a rock and does not smear or show any signs of distress or marks when resized in a Lee push thru sizer after coating.
I haven't shot this powder yet. I bought it because it has a flash suppressed coating and I'm looking for something to use in the .40 S&W and 10MM with PC boolits and less flash signature than Blue Dot. Blue Dot gives good velocity, but is a real flame thrower in the .40 and 10MM! Basketball size fireball. People at the range ALWAYS comment on that.
Looking at Alliant's reloading data for this powder, it should give great performance in the 9MM, .40 and pretty good performance in the 10MM with less powder charges and flash signature than Blue Dot.
I bought some Longshot for top velocities in the 10MM, but it seems to react with the PC also, although not quite as bad as BE-86 seems to.
I'm pretty confident in the PC curing, because I've got a lot of other powders covering boolits from this same batch that are not reacting at all with the HF Red or Smoke's Black PC. (Older Unique, Older Blue Dot, Older Universal, Older Red Dot & AA1680). Not a single flake of these powders have stuck to Smoke's Black, and these boolits have been soaking for six months or longer.
I don't know why there is a reaction with some of these powders. the layers of stuck BE-86 really shocked me.
The High Road has a good thread on BE-86. A poster claiming to be an Alliant rep. posted comments on the properties of the powder. Claims the powder has been around for 30 years and they have produced millions of pounds of it for use in LE rounds. Just introducing it to the public in the last few years (the thread started in 2014). Specifically, see post #2 and #153. It sounds like it is not a new powder. Maybe the flash suppressant is causing the problems.

Sorry for any typos, I can spell, I just can't type.
