Thought I would share my success with you pards. I have an 1887 Chinese replica imported by Century Arms (PW87). I purchased it in 2014 and sent it to Coyote Cap who had it four four years (he got sick and couldn't work). I got it back last year and I enjoy shooting it in matches even though it can be slow (technique is everything).
The success I want to share and some of you may already know, so forgive me for ploddin' on. As ya'll know the 1887 was made to shoot 2 1/2" brass shotshells. The reason people have problems with it running consistently is because the PW87 doesn't care for 2 3/4" shotshells. The crimp tends to catch on the chamber mouth during ejection. I was told the Chinese replica was redesigned somewhat for 2 3/4" shotshells but I don't see it. Dimensional wise it is the same as the original.
A simple solution is to buy a case ($110.00) of RTS, 2 1/2" shotshells.

MEC sells an adapter plate for their loader for 2 1/2" shotshells. I load 1 ounce of 7 1/2 shot over 16.5 -17 grains of Red Dot powder with a Winchester plastic wad. I had to develop that load myself because there is not a lot of load data for 2 1/2' shotshells.
Bottom line is the 2 1/2" shotshells run consistently in the PW87 and you can shoot just as fast as you can drop two in at a time. You still have to drop the lever all the way down, but it seems to eject smartly every time.
