Winchester Mirouku 73
« on: April 10, 2016, 08:44:24 AM »
I recently purchased a 73 Winchester made by Mirouku ( some call it a Japchester) After having a gunsmith install a short stroke kit from Pioneer gun works, this rifle is the smoothest, fastest rifle I've ever had. It's a 20" short rifle and has a round barrel which makes it lighter than my Uberti 73 with an octagon barrel. Just wondered if anyone else has one and how you like it??

I have two of them. 357 and 44/40 calibers. They both are factory original and feel really smooth to me.
The 44/40 really likes the Meister .430 bullet and 8 grains of unique. 3 inch or so groups at 100 yards.
The 357 shoots anything. The 38 specials have to be at least 1.450 inches long.
I think the fit and finish is outstanding.

     Have the 24.25" oct barrel .45 Colt in Grade "Plain Jane" I; fit/ finish is flawless, action extremely smooth - fun gun to shoot - it is certainly a keeper - glad you like yours.

I just got on of the short rifle models, but it's so new I'm still collecting components to work up a hand load for it. Just looking it over and handling it (working the action) it seems to be very well made and reminds me of the 1889 original I used to own. (smile)

After having finally handled a new Winchester '73 I figger I now need one. Color case, 20" in 44-40 of course. I loved the balance, fit and finish. Not quite as purdy as the Uberti '73, but was solid and just felt like it might be built better. Now, to find one...

I have the 73 and the 92 in 45LC.  I just got the 73 and went to find CAS parts.  PGW had a short stroke kit for me and I had to send the carriers back because they had the wrong part in the right package (357 in Large pkg)  So in a few weeks I hope I get the right parts as ordered and then I'll try it out.

I have one in 44-40. Been casting .429 bullets from a Lyman mould from 16-1 and filling the cases with either 12 gr of bludot, or 35 gr OE 2f. The bugger sure shoots good. Much smoother right out of the box than the Uberti 32-20.
 I did replace that uber tall front bead with an ivory blade, and that left me plenty of adjustment on the rear sight to shoot beyond 100 yds.

Please explain why the 38 specials must be at least 1.450 inches long.  I am very new to the 1873.  I just received my new Miroku Winchester 1873 Sporter 24" barrel and it has a problem cycling the 38 special through the brass lifter.

Real simple.  Measure the length of the carrier.  It is 1.600 inches long.  The gun was designed for ammo that is 1.590.  Once you get below a certain length the rounds are shorter than the bevel cut on the front of the carrier and they will jam.  The general rule of thumb is keep your ammo 1.5" or longer and you will have no feeding problems.  Remember this is a repeating mechanism and the ammo is an essential part of the feeding cycle.  73s have no cartridge stop.  What stops the next round coming out of the magazine tube is the round sitting in the carrier.  If it is to short to much of the next round is sticking out of the magazine tube and you will get a jam.  73s do not have problems cycling ".38s."  Most people shoot .38s out of them.  They have problems cycling .38s that are loaded to short for the design of the mechanism.

The shorter your ammo the more the next cartridge in the magazine will come back into the lifter area. When cycling the ramp area of the lifter has to push the cartridge back into the magazine as the lifter raises. Max length ammo always cycles smoother.
