I think the .33-47 I've mentioned here was probably the HiWall I had. Originally a .32-40, re-bored by Pope, set up for breech/muzzle loading, complete with a Pope mould, re/decapper, instructions, and receipt with notes and test target. On the receipt, Pope called it a .33-47, so I deferred to him. When I traded into it, I was given several pounds of old powders so was able to use Pope's recommended load, a duplex of King's Semi Smokeless and some high-grade Dupont BP. Great rifle; the bum who owns it now swore he'd keep shooting it but decided to retire it as a "priceless historical artifact".
I thought the cartridge was a (slightly) better choice than .32-40 for our Nebraska winds. (I really prefer a good .38-55, but even in a 13# rifle the recoil gets to you a 100-shot match.) A friend had a shot-out Winchester 94 .32-40 re-bored to .33-47, but in that role (smokeless powder and jacketed bullets on game) it wasn't any better than a .32-40--and it didn't have the Pope magic.
Years ago, I was at a gun show bemoaning having missed a Krag at a local gun store. That was my Krag luck in those days, a day late or a dollar short. A friend at the show said he had one he'd sell me for $250 IIRC--sporterized, but a Krag. Since I wanted a shooter, I didn't care, and the deal was done.
I took it to the Lincoln Ike the next day, shot well over my head, and was very pleased with the rifle (even if it did have a pine pistol grip scabbed on to the cut-down stock). Took it home, stripped it down, and saw that the BOTTOM of the barrel was marked H M Pope. I contacted the seller, told him what happened and what I found, and asked if he'd made a mistake selling me the rifle so cheap. He told me he knew about the barrel, and that he figured I was the only person he knew who would enjoy having the rifle as much as he had. My intro to Pope's magic.
After some research I figured that someone had acquired an orphan barrel and put it on the Krag. Pope would have used better sights!
