Today I finally got to shoot my "new" 45-70 1895 Cowboy at more than 20yds!
Still only 110yds but useful for setting a woodland hunting zero. I've fitted a 1-4 Vortex PST scope on a Williams Ace-in-the-hole combo-rail.
I was pleasantly surprised by the accuracy with 405gr SP loads:
The calipers aren't pictured quite right but it's easily a sub 1 inch, 3 shot group at 110yds. This was shot with forend supported on a block, rear unsupported.
The butt cover from this thread worked well with respect to increased length of pull and comb height. Recoil was ok, probably helped by the 1inch of padding inside my butt cover.
Lovely gun to shoot.
