1891 Mauser to .45ACP?
David R. Birch
had an idea to rebore the barrel and rechamber it to .45ACP. Anybody
know of a good gunsmith that rebores barrels?

Argentine Mauser I have and
had an idea to rebore the barrel and rechamber it to .45ACP
~~~~~-
45ACP, I wonder considering the barrel length, would it help or hurt
velocity, and in turn accuracy. You can only squeeze so much juice out
of a turnip, until you destroy the turnip. Than there is the .45 ACP
cases fed and ejected in a throw bolt. I think the barrel reboring and
re-chambering is one of many other steps you’ll have to take, but
stranger things have been successfully accomplished out of ones
inquisitiveness...

barrel blank and put it on a 1903 Turkish Mauser.

That has been a fun project, and everyone at the range likes to shoot
a pistol cartridge in a rifle, with no big noise or recoil.

Can be done, it's been written up. Best bet is to find a .45 ACP
blank, like from Numrich/Gun Parts and carve a new barrel out of
that. If you've got the tooling, go for it. If not, you're looking
at a wallet drainer. Reboring probably wouldn't be any cheaper and
you'd end up with a paper-thin barrel at the muzzle. Basically, you'd
be building a Destroyer carbine in .45. If you've already got a 1911
or Glock, you can get a carbine conversion a lot cheaper than what you
propose to do.
You won't get that much extra out of a stock .45 load by lengthening
the barrel. And souping it up won't make it that much better that
it's worth doing for the extra omph.

There are certainly gunsmiths that can rebore a rifle barrel (Dan
Pederson at Classic Barrel Works www.cutrifle.com comes to mind) but
the average rifle barrel will become quite the thin walled tube
especially out towards the muzzle once you rebore from .311 to .452.
It will be much simpler and less expensive to have it rebarreled as
Clark described. Are you planning also to have the magazine well
adapted to accept a 1911 pistol magazine so that your 1891 will remain
a repeater?

Another possibility is to make a liner from a .452 blank. My 1911 barrel
is .577", the 1891 barrel is .688" at 20", so I have lots of barrel
diameter.

That would be practical, I want to do this for fun.

blank.
For the mag, I might try a spacer at the front of the mag and a
shortened follower at the rear. My Moroccan M98 carbine in 7.62NATO has
this arrangement and it works well. Otherwise a 1911 mag might work if I
don't have to mill out too much clearance from the inside of the 1891
mag walls.

Magnum, for more power, 0.3" longer than .45 ACP, otherwise the same
dimensions, just run an .45 ACP reamer in 0.3 longer, use a dummy
round until the bolt will close on it.
MidwayUSA has .45 Winchester Magnum brass from starline for $22.99 per
100.

Has .45 ACP liners.
Or why not just reload the Argentine Mauser rounds with a 70% density
load of Trail Boss and 135 gr or 140 gr gas checked hard cast .312
bullets from
http://www.beartoothbullets.com/bulletselect/index.htm
You could load up a large amount of these, for the $ cost of any
conversion to .45.
For accuracy, cut the barrel back to 25" and put on a new front sight
of approx the same hetght less 1/2 the cut back tincreasd barrell
muzzle diia.,minus 1/2 the the original dia.of the muzzle

No, thanks, I want it to shoot .45ACP.

Thanks, but what I need is a recommended twist for .45ACP (16?) and a
reference for someone who can rebore, rifle and chamber the existing barrel.

The barrel is already cut to 24" and I'd like to take it down to 20".

Here is a company that does specific Mauser/45acp conversions, but
they use a replacement barrel.

Very cool. up until now, I thought I was the only crazy person that
wanted to do this. Now I need to find another Mauser to convert...

I looked at these a while ago before they had Mauser small ring
conversions. These may work with the 1891 although the 1891 has a longer
barrel shank than the later models. Obviously the magazine parts aren't
compatible.

About what I figured, somewhere between too much and too damn much.
OTOH, Krieger is just a little ways down the road...

The http://troupsystems.com/index.htm website states "Mauser 45kits
are in stock and shipping, both large and small ring kits."
What makes you think that the magazine parts in the small ring kits
won't work?

The 91 Mauser had the drop magazine
http://leadingthenextinquisition.files.wordpress.com/2006/08/mauserbolt-large.jpg
The 93 was the first Mauser with the staggered internal magazine.

Everything I see there is for a '93 or later action, not the earlier '91
single column mag.
