There was bring any firearm shoot sponsored by the Utah Gun Collector’s Association on Friday June 18.  I dug out this 1887 vintage model 1876 in .45-75.  It is a standard rifle with 28 inch octagon barrel and straight stock.  It does have an excellent bore and a set trigger that works.  

At the shoot there were fully auto Thompson sub machine guns, quite a few military surplus rifles, some various handguns, black plastic rifles, muzzle loaders, and black powder cartridge rifles including this 1876. 

I used trimmed and resized .348 Winchester brass.  It works very well in these old rifles.  I can get about 65 grains of Goex 2F powder in and use a large magnum rifle primer.  Bullet is from Ideal/Lyman 457192 which drops a 350 grain bullet identical to the Winchester mold.  In the photo my reload is on the left and an original round is on the right.  Just put in enough powder so the bullet seats on top and gives light compression.  A wee bit of crimp just to keep bullets from backing out while in the magazine under recoil.  

Rifle shot well with no problems.  The loaded rounds chambered correctly and the empties ejected with no issues.  These 1876’s in .45-75 were very powerful black powder rifles for their day.  It’s fun to relive a little history of the old west.

  

Bill – very cool.  It looks like both you and your M1876 had a fun day!
