I have a 3rd hand Shenandoah flinter that started out as .36 and is now .46. I like it a lot but think it's gonna get scraped down and refinished.
PS,
This Shenandoah was a real adventure as the person selling it didn't tell me the barrel had been ringed and that he had messed up the lock. I fixed the lock and wanting to keep the rifle, had it rebored to .46. If buying one 2nd hand, feeling out the bore with a tight patch is now my SOP.
PPS,
When Hoyt rebored the .36 he also improved the ignition performance and cleaning characteristics with a little rework on the breech plug. The man is a national treasure.
Wrestled with whether to go .40 or larger on the Shenandoah but settled on .46 for greater utility. Ended up with the weight and feel of the rifle being just peachy.
