ok butlerford 45, i'll try,,but I aint good with words. k?
I feel haywire heywood would be better served as a new shooter of bp guns using a faux bp of the proper grade than using cartridge grade goex in his gpr. my experiance of trying to save $ useing the inexpensive stuff just to shoot lent too alot of shooting and missing alot of target.
i was confused? I wanted accuracy. Then I discovered,,these bp guns ain't just little cannons' that deserve nothing but (some)powder and (a)projectile too shoot. I began too participate with others shooting bp arms.
cartridge grade is dirty,, patched round ball dosen't (imho) develop the enough pressure for the catridge stuff to burn proper in the bore. that prb is out the muzzle afore the powder is done burning it lend "MUCH" fouling for a gun like the gpr, and all that icky black powder using shooting stuff is a hard thing for a new shooter,,truth.
So, No. don't use cartidge grade powder in your gpr.you will have fouling and cleaning difficulties. some other guy said it works in some of his guns,but it won't work in another,,and he never tried it in a capper.(sheese!)
Now here's a question for ya bf45. Have you ever "seen" a manufacurer of a cap-lock or flint-lock gun recomend "cartridge grade" powder? either in history or current?
I don't want to argue with anyone butler,an there is "so" much info on this site and it's archives,,,,,,just read some.(?) uuhmm, Bill Knight anyone?
