The binding problem in my Paterson is similiar to the same problem I had with an Uberti Remington - actually worse. The cylinder would not rotate more than 3 or 4 shots until I switched to the beeswax-paraffin lube pills made by Wayne (Rifle). Now it's completely fine, but I do wipe down the cylinder pin after each 5 shots - might as well, since I have to pull the barrel off to load the gun.
As far as accuracy - the barrel is 9", the gun is light, it's a five shot .36 caliber, so the powder charges are light. Not much kick at all. I shoot mostly at targets in the snow or dirt, so I can't report on grouping sizes, but I usually hit or almost hit what I'm aiming at with this gun.
It's not an everyday shooter - it's too hard to take apart and clean. Removing the barrel to load can be a pain at first, but I like it now. I like Coors Light or Bud Light beer - a Paterson is more like a dark heavy beer that you have to acquire a taste for.
For cold weather shooting I usually reach for the Ruger Old Army or the Walker, guns with some size to their features to aid cold numb fingers. But the Paterson is a great addition to a BP collection. Just gotta have some patience and some technical know-how (I'm trying to get some of each).
I wish Uberti would have send me that Paterson they traded for a Dragoon.
This is how you load it - remove the barrel, load the powder and ball into the cylinders, put the end of the loading lever tool in the arbor slot and ram.
