Purchased a canister of APP to try in my .50 caliber Encore. Was shooting 100 grains by volume and using Winchester 209 primers as the ignition source. Fired off about 20 rounds.Upon getting home and beginning the leaning process noticed that the inside cup section of my breechplug was pretty much loaded up with a sugary type residue? Now I am aware that APP issugar based (ascorbic acid?) but is a build up natural? Would a different primer, maybe less hot than the Winchester be a better choice for this powder? Your thoughts.....
The statment that APP is sugar based is a little misleading. One way of making ascorbic acid (which is vitamine C) is to use sugar as a source of the acid. The result does not have any characteristics of what we would recognize as sugar. I have seen others refer to the APP fouling that sometimes occurs. I have not shot a lot of APP so I cannot comment. I have shot Black Mag'3 which is similar in form and the only thing I find in the barrel is some gray powder. I use the .25ACP conversion in my Omega with Winchester small rifle primers.
