It is critical that the 351 cartridge is reloaded to factory specifications.  The blow-back action will not function properly with loads that are too light, and if too heavy, they will damage the action (buffers).

Bert,  do you know whether the 351 was intended to headspace on the case mouth or the vestigial rim? 
  

While I do not positively know, I highly suspect that it head spaces off of the rim.

I agree with Bert.

Speaking of modified Model 1895's, I am interested in Lot 3053 in the upcoming Rock Island auction.  It is Serial No 1949, a Flatside musket listed with a Stevens-Pope replacement barrel.  Can anyone tell me anything about Stevens-Pope replacement barrels and why this rifle may have been re barreled in this manner?
  

Pope was the premier target barrel maker in the late 1890's and early 1900's.  He worked for Stevens from about 1901 to 1906.  Target rifles usually have longer barrels. 

I can't argue with you on that one!

I see a few salvageable parts!

Nice Model 1873 Sporting Rifle! 

My bet would be that the script letters on the carrier block were added by one of the previous owners after the fact.

Looks like a nice honest and clean M-1873, (third model), Antique rifle in the .38 wcf caliber. Not sure what the three engraved, yet nice looking, "M.S.W.", stands for, if I got it correct. It's also nice to have the letter with it. No mention of the 3 engraved letter on the brass elevator, on the letter, as you mentioned.

Nice find!

Thanks for sharing.

There are some very well done scrolling initials inscribed.  Nothing on the letter. There is a possible story, but I’d like to hear the experts opinion……

I've since had a closer look at the chamber on mine and there's no "bullet seat",  just a tapered leade, so there's nothing for a case mouth to headspace against. 

The "semi-rim" concept was devised to [A] allow cartridges without a shoulder to stack and feed reliably from a straight-line box magazine but [B] still headspace on a vestigial rim. It does not provide best accuracy, which is better achieved by a rimless case that headspaces on its case mouth against a 90 degree "hard stop" milled into the chamber. 

A classic example of the difference is Colt's Super .38 Automatic pistol cartridge, which is semi-rimmed and was ( and still is) chambered in a commercial variant of the Colt Government Model pistol and in the steel-framed Commander.  The barrels of these pistols were chambered to require the cartridge to headspace on its tiny rim, resulting in variable cartridge positioning. For Decades Super 38 pistols were  notoriously inaccurate compared to the ,45 ACP guns, although sufficiently accurate for close range combat. The Super .38 is powerful enough to give the .357 Magnum a close run.  Lawmen and gangsters bought it for that reason during Prohibition and later. Particularly in Dallas. 

Eventually, several gunsmiths - notably John Rollins and Richard Shockey, discovered that Super 38 barrels cut to headpace on the case mouth like the .45 ACP were capable of being tuned to match grade accuracy. Irv Stone commercialized the idea and his Bar-Sto Super 38 barrels were all the rage in the Seventies and Eighties. 

Once Colt's came under management that cared about what it was doing, Super 38 automatics coming out of Hartford had factory barrels cut to headspace on the case mouth. They give good accuracy out of the box, at least equivalent to the .45 versions of the same gun. What a talented pistolsmith can do with either caliber is astounding (to me.)
