Yes, shoot '63 Remingtons in .36 cal. using both the cap 'n' ball cylinder and conversion cylinder.
I have two, one an early Uberti with the more correct small Navy frame, and one built on the same size frame used for the .44 Army. Nipples changed out to SlickShot. The nipple housing on the large frame cylinder I opened up to give more room for a capper. (Cash inline) The small Navy cylinder has a bit more space to get capper in.
The fit of the Navy grips is perfect in my hand, the Army feel a bit "fat" when held in hand. Still shootable.
Uberti pins have a flat milled on one side so no need for relief cuts.
One of the nice features of Remington, they sight better than that teeny post and hammer notch on a Colt. The continuous "V" trough atop the cylinder strap and front blade are much easier to acquire for my aging eyes.
I shoot both Colt and Remingtons and do feel the Colt has a tad bit better natural pointability for me, but practice and muscle memory makes shooting both no issue.
I do not have cap jams with the Remingtons, nor in truth very few with either now that nipples have been changed out to properly fit caps. One advantage of Remingtons is much easier to remove cylinder for cleaning, or if changing out to another loaded cylinder. I will often start with loaded and capped cylinder and switch to conversion if called for by stage instructions when a reload.
