Mossyed across an older Lyman GP percussion today in 54 caliber. After all the T/C 50's I've owned over the years thought this might be a fun diversion. Other than the fact that a former owner pinged in a new flip up rear sight, an aftermarket front sight with a white bead, it is in really good condition. I may see if replacing those with original factory sights is an option, or screw in an aperture rear sight in the hole tapped in the tang for that reason. The current sights don't line up naturally when I throw the rifle to my shoulder, but they aren't actually made for this barrel, either.
Online sources show anything from a 1/32 to a 1/in 66" twist. Using a tight patch on a long ramrod marked at a measured 32" did not turn a full revaluation. That was pleasing as I aim to shoot RB's in it. Then, with two pieces of tape 24" apart shows half a turn in 24"+/-. I'm taking this that this rifling is basically 1 turn in 48". Does this twist seem right with these Great Plain Rifles? I need to get up to speed to see how best to feed this long gun.
Also, with two cans of ffg on hand, what do you find as a good starting load for a PRB? I hunt and so will this rifle, so slow target loads are not what I am interested in.
Thanks in advance for the replies,
