Hi, I just picked up a nice original second year of production winchester model 1887 today and it’s in pretty nice shape

 

I’m looking to shoot it and I was told to shoot either low brass shells or birdshot

 

I know that some people also shoot reduced smokeless loads

 

Does anyone here have any know on shooting these old winchester shotguns?

 

I bought some winchester AA super sport sporting clays 12 gauge ammo today, the ammo is 2 3/4in which it chembers, it has a velocity of 1,300fps and it has 1 1/8 ounces of 8 shot. Would this ammo be safe in this gun?

 

Thanks

Do NOT shoot 2-3/4″ shells in your Model 1887!!!  The Model 1887 was chambered for a maximum 2-5/8″ length black powder loaded shell.  Shooting modern 2-3/4″ shells in that old gun can cause catastrophic failure.  A 2-3’4″ shell is not full length until opens up on firing.

Smokeless powder shells can be shot in a Model 1887, but they must be loaded to low-pressure (<9K).

RST manufactures 2-1/2″ 12-gauge shells that are safe to shoot in a Model 1887 that is in good mechanical condition.

2 3/4″ shells may fit BUT when fired the end of the shell opens into the forcing cone and results in a constriction which combined with the modern powder charge raises the pressure to unsafe levels. Please don’t try it. I think 2 5/8 shells are available if you’re willing to look.

RST lists them, but they’ve been OOS for a loooooooong time now. I wish they’d run some, I’ve been waiting a while….I wish I knew a reloader Laugh

Jeremy et al, Check out Buffalo Arms.  They have in stock 2 and 1/2 inch 12 ga, in black powder and 7 and 1/2 shot.  Price is steep at $56 for a box, but it is in stock.  Other than that, I would contact Ballistics Products and buy hulls, wads and a drill driven roll crimper.  Hand operated it works but can look ugly. In a drill press it looks way nicer.  Either one will feed if you ensure the ends are tapered.  Were you living in my area, I could have you over and guide you to loading your own, but loading for another is fraught with liabilities.  Tim

I know this is about a 12 ga. but I’d double check the chamber on yours.  Years ago I bought an 1887 shotgun in 10 ga.  I was told to use 2-7/8″ brass.  When the new unprimed brass arrived they would not fit.  I returned them for 2 5/8″ which worked.  Maybe some were 2 7/8″ but not mine. 

Do as the others have stated, don’t use the longer shells.  

Tim, I’ll have to see if they have some of the shorter 20 ga.  I might need some for the 1885.

Chuck,

Your Single Shot (M1885) 20-ga high-wall shotgun has a factory 3″ chamber… short shells are not needed.

Per the 1914 and 1916 Winchester catalogs…

I suppose they would be too high pressure, but what about these mini or shot 12 ga. shotshells that are out there.  Two inches long?

I just realized the OP was talking 12 gauge but in my mind I was stuck on my own 10 gaugers….anyways, buffalo arms does seem to have them in stock….here’s the ten gauge version: https://www.buffaloarms.com/10-gauge-2-5-8-3-3-4-drams-of-amobp10ga2.html

I’m sure you have told me this before but if I don’t scratch it into the back of my hand, I will forget. I updated my file to show 3″ shells.   I do have several cases of 20 ga.  Probably 1 of target and 1 for hunting.  Maybe I’ll take a 3rd gun to the range tomorrow.   Thanks.
