1866 tight action

[nativeshootist]

I recently changed the barrel out on my 66 carbine due to circumstances. And now the action is tight when the bolt closes onto a round. I can't seem to find something similar. Any suggestions

Does it do this with ammo only or also when empty?  It sounds like you don't have enough (any) headspace.  And I think that means that the barrel needs to have material removed from the rear face and then re-chambered.  Some of the makers of short-stroke toggle links have sets that are longer to correct rifles that have too much headspace.  I don't know if they also make sets that are shorter for the opposite reason.  I haven't heard of those, but maybe? 

Maybe one of the 'smiths on this site who actually knows these things will chime in

Headspace is bad.  Optimum headspace is .004 on a chambered cartridge.  Material needs removed from the breach end of the barrel or the face of the Breach Block.
