.44-77 and paper patch?

[Caprock]

Jim the paper is sethcole 55y
The accuracy difference between it and 55w is significant
The use of jobs oil on the exposed patch of both papers is also pretty significant Fromm 600- 1000
The barrel is a gem heavy sharps profile mounted on my Shiloh rough rider and chambered in 44 90 Remington straight.
Cases are jab 45-90 sized down rp 91/2 primer 84 grains OE 1 1/2 thin napa rubber cork wad on top the powder muzzleloader original dry line felt was under the bullet which is seated about 1/4 in into the case

Wow! There's just not that much diff in 55w and 55y thickness wise. Who'd a thunk!
