Cayugad there are a couple problems here: (1) This stuff doesn't perform well in traditional rifles. The coarse grains and high ignition temp make it less than ideal. I used to shoot 3f APP through my hawken for awhile before switching back to Pyrodex recently for more positive ignition and power(it was worth the mess). It takes too long for the APP to get fired and going to deliver much power and accuracyin a sidelock. Although, it does perform quite well with hot 209 primers in inline rifles. (2) Your grain is 3f. The answer for me with APP has been 2f in not only my 2 inlines but one my friends inlines also when we were experimenting. I'm just passing the tips that I've already hassled through myself My omega/kodiak prefer a 120gr charge and a 250gr shockwave; this groups under 2" consistently. Also, don't swab; I only swab once every 3 shot group, and shoot on a dry barrel the first after that.
