It is very hydroscopic (sucks water out of the air) it has alot of good qualities but consistant accuracy and velocity isn't in the mix. Big difference in POA if its been sitting in the barrel all day, I finally gave up on it.
actually the (sucks water out of the air) is very untrue. Ive had rifles loaded for a week and 2 weeks and both shot their original POI. Now if the powder does get wet, it basically will turn into a hard "Pellet" I had it happen while testing a rusted barrel, the nipple threads were letting condensation get to the powder in the bolster and it was a solid block. Fired off perfectly. Some teflon tape on the threads sealed it off from moisture after seeing that, i do it on all of my sidelocks. Consistent seating pressure is the most important thing to do while shooting the powder. You have to seat the bullet until you feel the powder compress, then its ready. It likes hard seating.
I tried the sticks. It seemed to me that there was a bit of waste putting the square stick in the round hole.. It was easier to clean though. If you were not dilegent about the breech area it did build up a ring of crud... I wasn't impressed with it. I'll stick with my good old pyrodex ..The old Ford vs. Chevy thing
I have shot APP and found in some rifles it shot real well. In other rifles no so well. Just like any other powder I have tested. I did like how well it cleaned up. And like said, really seat that bullet. Right now I am shooting JSG 3f and seeing what it will do.
