I have two reproduction 1876’s chambered for 50/95 WCF.
One is a Chaparral carbine and the other is a Uberti Presidio carbine and both are an extreme pleasure to shoot.
Both the Uberti and Chaparral group extremely well with my handloads which launch a 350 flat point bullet at 1450 FPS using a stiff charge of H4198 and standard rifle primers.
This is an 75 yard group with the Presidio using the above mentioned load.
And here’s a hundred yard group with the Chaparral (again using H4198 and a 350 grain flat point boolit).
I have experimented with boolits up to 450 grains in the Chaparral and they too shoot very good groups albeit about 12” lower than the 350 grain projectiles.
This is a 100 yard group from the Chaparral fired using some .515 450 grain boolits meant for the 50/70 govt using H4831 as well.
The POI was so low I had to hold well above the steel cross bar on my target frame to hit the steel.
As you can see, these reproductions chambered in 50/95 wcf can be made to shoot extremely well.
With regards to hunting and the 50/95’s performance on game, I’ve had neither of mine in the field so I can’t speak specifically to that concern.
That said, having taken game with cartridges having similar performance I would have complete confidence using the 50/95 cartridge on any North American game within the limits of my shooting skill.
