There has been only 1 black powder cartridge rifle that I didn't like shooting. It was a LoneStar roller, in the silhouette configuration, ie: pistol grip stock, double sets, actually a heavy enough barrel, in 45-90. I fired that gun 1 (once, uno, one) time and it hurt. The stock comb was not high enough for me to get on the stock right. I have a couple 45-110's, a couple 45-100's a 45-90 in Sharps and CPA configurations and they are all pleasant rifles to shoot.
There was just something about the geometry of that roller that didn't fit. That is why I suggested the highest comb possible and configured to get the rifle recoiling straight back.
Here is another source of stocks

(or as a hunting gun, but then you configure it different/lighter and you don't shoot it often as that wouldn't be fun).
The 45-110 is really made for 2 things. Sitting on a hillside knocking off bison (which was ruined for us present day folks well over a 100 years ago) OR sitting/firing prone on a firing line shooting at targets 1000 yards away. There is also the matches at Lodi Wisconsin, in which case the rifle and sights can't weigh more than 15 lbs unloaded
