I just got these nipples and when installed on my 1860 Uberti, the CCI # 11 caps rub against the frame and jam the cylinder. Seems that the nipples are too long.
# 10 caps are not available in Honolulu.
Maybe you've got the wedge pressed in too tight?
Wedge depth is a variable that is meant to adjust cylinder gap,,
That little clip in the wedge is supposed to keep the wedge from falling out when pulled, it's not meant to be pushed all the way to the far side as a clip or keeper.
Just throwin out ideas
The nipples are longer then the stock nipples. I don't want to do any work on them. :surrender: Think I'll just return them to Bad Man Bullets.
BTW, Track of the Wolf has a 90 day wait for 1860 Colt nipples
Slix-Shot nipples are made to work with #10 remington caps. I have tried CCI#11 and RWS 1075 caps
and they work so-so if you don't mind a few cap jams.
My guns are equipped with cap rakes so the jams are at the water table not the hammer channel.
I have no solution to your problems sorry.
