Winchester 1886 - rebounding hammers issues - yea or nay

[snowwolfe]

How many of you who actually own a Winchester 1886 in 45-70 that was built by Mikuro have experienced any issues with the rebounding hammer?

If you had any issues was it easy to correct? If you had any issues, did it affect the accuracy?

Thank you

[NSB]

I have one and it was no problem at all. However, I wanted Turnbull to case color it so while it was there getting that done I had them retrofit the safety and hammer. It now has no rebounding hammer and where the safety was it's all filled in and looks great. It doesn't shoot any different now. You will find that the gun has no throat at all.NONE. They ran a reamer in there and added around 20/1000 lead. I couldn't close the lever before without having to press fit the bullet into the lands and that was with 405g Rem JSP bullets.....not long bullets. My Miroku High Wall was the same and I did that gun also. I get pretty consistent groups of around 1.7" for five shots at 100yds. Real groups, not keyboard groups.

I have the extralight 1886, no problems with the rebounding hammer.

I had some misfires using hard primers. It was an easy fix, check out sticky:

I have a Marlin 39AS that has this feature and it drives me nuts. Everytime you fire the gun(if it goes off) the thing goes 'Boing!'

I mean an audible boinging noise that is not what you would expect to hear from a quality .22 like a Marlin 39A. It misfires 30% of the time simply because the way the hammer strut is made it starts pushing back on the hammer well before the hammer has struck the firing pin.

I will be retrofitting a earlier hammer to this gun eliminating that feature.

Randy,

It's not a Model 1886, but I do have a Winchester (Miroku) Model 1895 with a rebounding hammer. I've had it for a little over fourteen years, with no issues.

I have one of the new 1886 Short Rifles with the rebounding hammer. It has never given me any trouble.

Wow, not what I expected to hear (in a good way). We have an 1886 Extra Light High Grade coming in and I was convinced the first thing I needed to do was to either repair the "hammer" or send it off to be fixed before I even shot it. Makes me even more convinced we picked a good rifle.

[NSB]

No sense fixing it if it isn't broke.

[W.R.Buchanan]

Jon K: I have no idea. I have been told Numrich but haven't tried them yet. They have a habit of not updating their website and as a result you place an order only to find out they haven't got the part. You've got to call them everytime.

I may just modify my existing hammer so that the half cock notch actually captures the sear. As it sits the half cock notch does not and if you pull the trigger when the gun is on half cock it will go off. Not exactly the safety I am looking for.

Greetings
Have a Win jap 1886 Light weight in caliber 45-70. So far never a problem and it fires every time I want to touch it off. This rifle is one of my favorite walk around all day rifles. 3 rounds in the mag and one in the tube. Added a receiver sight to this one.
Also have a Octagon model with the 26 inch barrel. That is a nice cross sticks rifle. Carried it for 4 hours once... Definately not doing that again. But this one also has never failed that I remember. I did remove the safety and put a tang sight over that crevise.

I own a Miroku Winchester 1886 45-70. Never had any issues with the hammer, but I will reiterate what NSB said above;

"You will find that the gun has no throat at all.NONE."

The only molds (to date) that fit my (unaltered factory) gun have been my RCBS molds:
45-300-FN, 45-325-FN-U, 45-405-FN and a Saeco #017, 350gr FPGC.

I have a real nice NOE 350gr FPGC & an Accurate Molds #46-350B (350gr GC) mold but I can't close the lever before without having to press fit the bullets into the lands. These two particular molds however work beautifully in my Marlin 1895 Guide Gun.

The 300, 350 and 405 grain SAECO Moulds all work extremely well.

I have that very same accurate mold ... I also have trouble with every rifle I load it in with the exception of my Italian sharps. BUT my 460400B is just the medicine and it does not have that fat drive band ahead of the crimp groove ... which enables it to chamber in everything I have ... great boolit and does 1 1/2 inch at 100 in my Winchester [japchester] 1885 Hiwall rifle.

on the original question ... I obtained a winchester [nother japchester] 92 in 45 colt chamber with the rebounding hammer and wrist safety ... I concluded that I needed to "FIX" it before I even got it in my hand sooo ... when it got here I just took it out and shot the nards outta it to see what was going to happen ... worked like an old Timex watch ... no malfunctions and fed and fired every time.

If you have a smith open up the throat how long of a round can you run through the action of a new model 1886?

[Clay M]

I have three 95's and two 86's with the rebounding hammers ,and no misfires yet. Good to know how to fix it if the problem occurs.

[NSB]

Everything will go through. The action's plenty long, it's just the throat that's short. It's made to the original spec. No big deal to open it up. A very shot job if you have the reamer (once you get the gun apart).

[Gunlaker]

Pretty long. I don't remember the numbers, but quite a bit longer than in a Marlin 1895. For instance mine will feed a Speer 350 with an oal of well over 2.6". I can measure one if you like.

Chris.

[snowwolfe]

I would appreciate that.
Thank you

[NSB]

2.774 on mine after reaming using a Rem 405g JSP ogive.

[snowwolfe]

Good info, thanks:) After the rifle comes in need to find someone to open the throat.

I have these same molds and they work fine with the rifle.They shoot accurately, so I am ok leaving the gun unaltered.

I just measured my dummy round. The Speer 350gr is a pretty long bullet but has a slender nose. It'll feed and chamber in mine at 2.690" oal. It does have problems with a number of other bullets when loaded to standard length though.

I have a japchester light weight and had issues with light hammer strikes . Problem got fixed years ago by replacement with a browning hammer

[The Nyack Kid]

If one digs far enough back in the forums you can find discussions on the matter

[muskeg13]

I had misfires/light strikes with both an ELW 1886 and a 1895 bought in 2003. The problem was fairly regular with the 1886. The "Rifle" article came out about this time, recommending shortening the hammer strut. After following the recommendation, the problem was fixed. Fortunately, I haven't had much issue with the nonexistent throat with cast boolits (325-330 Gould and the 405 RCBS, which drops them at 415-420). I did have to seat 400 gr Speer SPs pretty deep, but I don't shoot them anymore.

You should be able to look up the hammer strut shortening procedure elsewhere on this website if you encounter problems with light primer strikes. Maybe Miroku solved the problem in rifles of more recent manufacture?

Kid - Where ya been? Welcome back.

[Just Duke]

I have a japchester light weight and had issues with light hammer strikes . Problem got fixed years ago by replacement with a browning hammer

Yea welcome back and thanks again fr the bullets you sent me 6 years ago.

[snowwolfe]

Cycled some dummy rounds through mine today, and yep, basically no throat. Rounds were only 2.5 inches long and you could see where several had the bullet seated even deeper after cycling.
I need to find a good smith to recut the throat, any suggestions? Would like to find someone local if I could around the Colorado Springs area.
