Gentelmen (Using the term loosely)
Allow me to impose. As a long term user of APP, I have NEWS. Well, information, not necessarily new.
Yes, APP is a SUB. The flame and "authentic smell" are not necessarily all they are cracked up to be (that should start a fight). APP may be used with ANY bullet, coated bullets, lubed bullets, BP Lubed bullets, BARE bullets. No matter. APP makes it's own "lube" and APP residue is NOT cumulative. Each round fired takes the residue from the previous round with it. Makes it super easy to clean up.
As a case in point, I don't have any "bare" bullets. I just order bullets from whomever has the bullet I want in stock ready to ship. Any lube is just fine. Most of my current stock are of the "Crayon" lube variety for smokeless (gag) but APP doesn't care. They shoot just fine.
Considering the ease of cleanup, no requirement for lube (ANY LUBE) I probably won't be bothered to return to BP. Just Sooooooo much easier. And yes ... I am Lazy. Old Guys get to be lazy.
