Went to the range the other day and took my Henry(repro) .45 Colt. Loaded her up, levered the first round into the elevator and the action wouldn't close . On close examination, I discovered I had failed to seat the bullet enough to clear the feed tube port .
If you have a Uberti repro of a Henry, make sure you seat the bullet deep enough to allow the elevator to lift it. The tolerance is very short.

Yer but best use a dummy round to test it out
at home. I suppose that round doesn't have a
cannelure as such? Maybe not even used in
lever actions until recently?
I had the same problem with a M92 win converted
from 25-20 to 218 bee by a gunsmith, wouldn't
even load factory rounds. From about 2000 miles
away I felt like riding the old hoss down and
sticking it up his lath or something.

I have some 45 Colt rounds for my pistol and tried them in my 1860 Henry Uberti and they wouldn't cycle(too long), and they were crimped in the cannelure. I have noticed that rounds for the Henry's do have to be at minimum lengths to cycle.
Jal,
Most bullets for the 45 Colt do have a cannelure on them.

My Henry is the Iron(steel) frame version, and it is a ball to shoot. I hope to get a Whitetail with it some day.
