I haven't seen that Colts are more prone to jamming than Remingtons. I have a Colt Signature Series 1861 .36 that spits out spent caps like a semi-auto. The Remingtons I've had tend to jam more due to fouling on the ungrooved cylinder pin (I use the spray PAM and it works wonders on those guns).
The Ruger Old Army is a great cold weather gun due to the larger ball and chamber size (easier for cold fingers to load), and the fact that they (well, mine) just do not jam.
