Well my new GPR .54 is actually two years old . I bought it a couple of years a go to get back into traditional Black Powder Hunting and things just got in the way. I finally shot it yesterday and used "real" Black Powder for the first time .I was using Graf's FFFG , 90 grains , Remington #11 cap, Hornaday .530 ball, with Thompson Center Pre-Lubed patches. I have no experience with Black powder but this stuff worked very well and was easy to clean up compared to Pyrodex (which is a b###h to clean) . I have some Goex to try but I can get along with Graf's just fine.
I found out after shooting a few rounds it was going to be necessary to swab the bore with some solvent every two rounds or I couldn't push the ball down the barrel.I got one stuck and had to pour in a little solvent in to get it to go down .I am expecting some improvement as the barrel brakes in. I was using CVA Barrel Blaster and it worked great. Also the pre-lubed patches seemed dry so I smeared a little extra Bore Butter on them and they worked much better.
After I cleaned the gun itself up I soaked the nipple in Barrel Blaster. I was very surprised at how much crud flaked off after soaking over night. All I did was wipe it off and run a "nipple" pick through and it looks new.
