Hi to all, in re-visiting the pictures it appears as if the 06/29 Swiss & the 70's Parabellum are designed and machined to follow the ramp almost immediately upon recoil and look to have a near symmetrical shape when compared to the toggle knob dia. ... As these were both later designs / copies / etc. maybe by time they were made, and in the case of the 70's Mauser, re-introduced, they had learned something that either reduced recoil, or improved function?... I'm pretty sure the "bear strong" magazine follower springs were an attempt to overcome some unforeseen or newly discovered deficiency, maybe the ramps were a corrective measure as well ?? I can remember on snowmobile racing clutches, the counterweights had curved ramps milled on the face to run against corresponding rollers. The curve, weight, length and contact point, (and other factors) had a tremendous impact on performance?... I would suspect the same on a Luger, as far as finding a sweet spot goes....
... When all was said and done, it could very well be a compromise for both calibers?... As in we've messed with this long enough, lets go!...
.. Best to all, til...lat'r....GT
BTW, if you were going to compare all of the ramps... The constant starting point would be the toggle knob diameter, (actually, bisected circumference?) all the ramp profiles could be graphed off of this one constant.... as it would track travel distance, curve/rate, and location, (high/low)?????? Maybe...
