When I got my first BP gun, I bought the pre-lubed patches. It was a .54.
Ask around at the gun club and started with 65 grains of FFg. Went to
85 grains all with the same results. Best was about 5" group at 50 yards.
Not to long afterwards bought an Allentown Flinter from a builder in New York.
It' s .45 with a Colerain barrel. He said he would send me some patches that he
used and to lube them with Hoppe's #9. They were .018 cotton from Joannes
Fabrics, used with a .440 RB. Take it to the range for it's first shots. At 50
yards, 4 shots, could cover them with a silver dollar.
So I thought maybe I'd try that in the .54. Same patch material, .530 rb,
70 grains FFg, lubed with Hoppe's #9. The groups shrunk to under 2"
Went to Joannes Fabrics and bought 2 yards of it for $8.25.
That was a long time ago and have never used a pre-lubed patch since.
As a sidenote, I've precut patches and cut at the muzzle, no change in
accuracy. I just happen to like the convenience of the precut.
