Its a double whammy for we with the crecent stock 1886's.
The LOP is way too short and the butt too narrow and pointy.
I bought a stock set from the Gunner a few years ago to get my 45-70 to where I could use it. Bought a wood carving kit to inlet for the tang safety. Had to take out a lot of wood.
Still use a slip on leather butt pad just to get a better LOP.
I bet a big Sharps rifle with proper stock length and design would be a dream to shoot compared to an 1886.
