Do you know if there are still ads in SGN for the 1891s?
I have purchased several 1891 and 1909s Cav Carbs thru mail order and they were all
very poor condition. Started looking several decades ago.
I would like to find a decent, VG or better 1891 Cav Carb. I have an engineers carbine which I love. Only now I only shoot it occasionally because I can't see the tiny sights. My first centerfire rifle was an unfired 1909 which I purchased at a hardware store about 1969. I still have it. Still my favorite.
My dad bought one too and I latter went back and got another. All unfired condition.
I later sporterized one because I wanted to see what it could do with a scope. I had no trouble out shooting model 70s ( un altered) with out the scope and got under 1" moa with the 6X Weaver and 50 Gr H4831 and Sierra 180 .311 bullets. Which I eventually loaded to an overall length that kept the bullet just short of the rifling. I also use IMR 4320 for a faster load in the 1909s using the Sierra accuracy load. I had to learn how to reload right away because at that time it was near impossible to find loaded ammo. So I wrote to Norma and they sent me fantastic reloading books no charge. IMO Argentine rifles are the nicest Mausers made. Perhaps the Persian models are great too but I have not seen one first hand.
1891 Mauser Rifle Magazine Feed Mechanism
Over the 2012 Christmas holiday I had my first opportunity to test fire a 1891 ('Argentine') Mauser rifle which I'd acquired several months ago.
I would like to post my analysis of the rifle's magazine feed action in the hope that more knowledgable people will critique my comments so that I can learn.
-----------------
The 1891 ('Argentine') Mauser has a relatively primitive magazine feed design as compared to the later Mauser rifles.
The follower is a simple flat piece of steel that pushes 'up' on any loaded cartridges and the only thing that keeps them from popping out of the magazine is that the left and right sides of the topmost part of the magazine (effectively 'lips' although they are merely bevelled sides) are slightly too close together for the width of one cartridge to get through.
The left and right sides of the magazine (the entire magazine and not just the top portion) are made of thin, springy, steel. It is quite easy to squeeze the sides slightly and impart a minute bow to the sides such that the opening at the top of the magazine can be adjusted to be slightly too narrow for a cartridge to readily pop up-and-out.
When the bolt is pushed forward its lower portion catches the upper edge of the topmost cartridge and causes it to begin to slide forwards towards the barrel's breech (at this point the entire cartridge is still held in the magazine by the narrow sides). As the tip of the bullet begins to ride up the feed ramp assembly this causes the forward portion of the cartridge to begin to pull through the narrow opening at the top of the magazine (the flexible sides of the magazine allow the too narrow opening at the top of the magazine to expand out slightly as the forward portion of the cartridge is pulled through the opening); during this time the rear of the cartridge is still held within the magazine by the narrow sides.
As the bullet continues to ride up the feed ramp the rest of the cartridge follows (being pushed by the bolt) and as this action continues the rear of the cartridge is finally pulled free of the magazine's narrow sides (basically pulled up-and-out of the magazine by the action of riding up the feed ramp).
Adjusting the width of the opening at the top of the magazine, and of the upward force imparted by the follower (caused by the two springs in the lower portion of the magazine), appears to be critical in insuring a successful cartridge feed action.
Too wide an opening of the top of the magazine, or too much upward force being imparted by the follower, and either will cause the cartridges (in some cases all of them) to be ejected out of the magazine. Too narrow an opening of the top of the magazine and the cartridge trying to feed into the breech will tend to jam as the tip of the bullet begins to ride up the feed ramp. (Too little push from the follower and the cartridges loaded in the magazine would lie in the bottom and not be pushed up against the narrow opening at the top of the magazine but this condition would be immediately obvious.)
The critical magazine adjustments appear to be having just enough upward 'push' by the follower to cause a fully loaded magazine (I could only get 4 cartridges in my rifle's magazine) to reliably hold all the cartridges such that they are up against the slightly too narrow opening at the top of the magazine and for the narrowness of the top of the magazine to be only as narrow as needed to keep the cartridges from popping out on their own. With these conditions met the topmost cartridge should not quite be able to pop out of the magazine until the tip of the bullet begins to ride up the feed ramp (and then the tail end of the cartridge finally pulls up-and-out of the magazine as the bolt pushes the cartridge further into the breech.).
