Hi Tobius:
I understand your point. The straigth pull rifles (Lee, Ross) were a failure with exception of a swiss model, but the separate magazine feeding of the Lee was quite modern in 1878. May I supose that your 1895 rifle will be a short lived one (specially if it cannot be modernized)? Cheers.
I do not change history that radically. Just as the Mauser (Springfield 1903 is a [Spanish] Mauser, [despite the window dressing nits] replaces the Krag.), so the Model 1895 will be replaced.
I think an AU Mannlicher style magazine feed bolt action rifle might be in the works.
I don't think the semi-rotating bolt and rocker ramp action straight pulls are conceptually lousy. One has to have some kind of lug locking at the breech to make bolt engagement work. Both tilt ramp and rotating bolt engagement designs work. And both can be either gas piston or barrel recoil driven. The trick is not to design a Ross-style action.
I've toyed with either operating concept, as the next art render. (See below, why this is historically difficult to justify prior to WW I.)
Historically, as I understand it mechanically, the Lee had some parts in the bolt carrier that were complex to make and small and easily lost. Also, over time, the hot gasses used in the Lee's ammunition burned and pitted the barrel lands, pitting and bubbling the same. The locking lugs could chip or wear down through the ramping action and that was a safety and [s]wear issue. The rifle just had too many design defects to be modified over time.
In the case of the Ross, (a semi-rotating cam action), the bolt came apart into (three?) pieces and could be reassembled incorrectly so that it could be reinserted into the carrier, so that it appeared to reseat properly. However the bolt could seat in travel and be too short in travel to engage the lugs by cam action. The recruit, Private Fumbles, would operate the cycle and the bolt could travel back in recoil and rip his cheek or break his jaw. Exploding Ross rifles are a myth, I believe. But being punched in the face by your rifle because it is smarter than you are, is not a recommended battle rifle solution.
A successful straight pull rifle (with a semi-rotating bolt cam action built into the bolt), might seem to be the straight line engineering path to a self loading rifle. Obviously it is not, because Mosin Nagant, Mauser, and Springfield users successfully arrived first, with Federov, Garand and Holek designs.
I still think Browning beat them all with a recoil operated split bolt carrier, rotating bolt design ~ 1900, that FN sold as the Model 1900. Why did the US not pick it up? Private Fumbles would somehow disassemble the complex expensive to make bolt, lose the two springs and not keep the action clean. Comparatively speaking, the design is virtually idiot-proof to assemble, unlike the Ross, but it is not idiot-proof in maintenance. And it will absolutely not take a bayonet. One, also, has to know (the simple) safety and cleaning protocols and follow those religiously or the rifle will fail to function.
WW I trench warfare candidate, it is not. Good for hunting Clyde Barrows though.
