Hi!
I have a 7445 Stainless .445 DW.
Today I switched out the barrel for the first time. I used a .002 feeler gauge. With that gauge, the cylinder did not clear the forcing cone very well. That is, as I dry fired, snapping through chamber after chamber, the cylinder would first rub against the forcing cone and then clear it and then rub again.
Has anyone ever heard of that before?

to the 
. You have a great gun there; do you have any 
. We love ..............
. On the gap issue, I believe a .006 gap is factory setting, but I usually set it as close as will allow cylinder clearance so it does not bind the cylinder rotation. That's what it sounds like you are experiencing. You should set the clearance to the tightest chamber. Not all cylinder faces are true, and if you set the gap on a chamber that is further back than another the cylinder will hit the forcing cone on the close ones. I usually set the gap and spin the cylinder with the hammer held slightly back to see if it hits anywhere, looking for just a bit of daylight in the gap. Not very scientific but I usually can't get the .006 gage in.
Anyway, I hope you enjoy the forum and there will certainly be other members chiming in to give their three cents on the subject. Give us a little history on your Dan and if you're the original owner or have date of manufacture info we could always use this info for our s/n database.

aboard, glad you're here.
As Jaggman said, it's not uncommon for the cylinder face to not be completely true and square. Especially if it's a Monson or Palmer gun...the Norwich guns were made with more modern tools & usually have much improved tolerances.
Just find the tightest hole & set your gap from there.
By the way...got any ???

Actually, the correct gap (according to the factory) for a 445 is .002 (sorry to disagree with you Ed 
); I set all of my Dan's to .002 at the tightest cylinder position and have no issues with any of them. However as others have said, you need to set that at the tightest cylinder rotational position if you have a Monson or Palmer gun.
Your description sounds to me like you may be experiencing front to back cylinder play if, as you seem to be saying, the cylinder first binds and then clears at each position. I may be misunderstanding.
and to the .

Thanks, everyone for your very insightful answers. I was a little concerned that I would not be able to get across what I was trying to say. But you knew just what I meant.
This is my very first revolver. I am amazed to find out that many cylinders are not dead-on true, especially for DWs. But if it's as common as it seems to be having read these posts, then I guess I won't worry about it.
Unfortunately I don't own a digital camera, so I've got no pictures. My revolver loks exactly like the one on this page with the blonde grips, except that mine has dark colored wood and no autograph.

I think that once you find your tight cylinder & set the gap from there, you'll be off & running. DW's function remarkably well with the gap set at that "tight spot", you'll see.
BTW, is that Jesus or "Hey Soos" (as pronounced (and credited) in the early 60's the Rawhide TV series)...?? hehe

Mike is correct...SuperMags used a .002 gap, the others used .006. Welcome to the forum!

Mike,
Now I thought the only one was the Model 40 for the .002 gap. Thanks for the correction. My 7445 came with a .006 gage.
