I have a Monson 357 which is having cylinder binding issues.  I have ruled out the barrel gap issue and cylinder face issues.  The cylinder starts to bind after about 60 rounds.  I can take apart the cylinder, clean the crane and ejector rod, and the revolver will work great until around 60 rounds.   

I thought maybe the cleaners were gumming up, but used carberator cleaner to complete degrease.  Still having a problem.

The loads I am using are 38 Special cast 148 Lee Tumble Lube wadcutters which there is no signs of abnormal leading.  Charge is 3 grains of Bullseye. 

Has anyone had a similar problem?

Greetings

Have a 15-2 that I bought used that was that way.  Tried everything I could think of and all the remidies other DW shooters could conjure up.  My problem ended up being a bent crane.  Sent it to DW (back about 1984) and they repaired it free.  Mike in Peru    proud-to-be-an-american

What is your barrel/cylinder gap set to?

If the gap is too tight, the heat can expand everything just enough to bind the cylinder. By the time you've taken it apart & cleaned it, everything's cooled down enough to not bind.

It will bind even when cooled down. After cleaning problem goes away until shot around 60 rounds.

I will keep my eyes open for a crane.  Numrich is out of stock, but for $17 it is worth trying.  Thanks!

I switched to 3.5 grains of Titegroup with a 150 grain Lee SWC which seems to have helped.  The Titegroup is burning cleaner than the Bullseye.
