Iver Johnson Cylinder

My latest "project gun" is an old Iver Johnson Target Sealed 8. It was out of time and the barrel was unbelievably leaded, but I got that all taken care of. The problem now is with the cylinder. The .22 cartridges will not fully chamber without a bit of effort. I've swabbed, scrubbed, and brushed until I couldn't swab, scrub, or brush any more and still have this problem. Was the cylinder designed to have this "interference" fit? Or do I need a chamber reamer to clean up the holes? Also, how did Iver Johnson plan for shooters to remove the spent brass from the cylinder? :roll: The gun is not equipped with any kind of ejector rod.

Any comments or help with this situation would be greatly appreciated!

Some .22 ammo uses a very heavy wax lube and you might have to push those in slightly to seat them in the cylinder but that is unusual. Are you sure the revolver is chambered in .22 Long Rifle and not a shorter .22 rimfire cartridge?

No, I'm not absolutely sure, but everything I've read about the I-J "Target Sealed 8" says it's long rifle. The cylinders don't appear to have any kind of shoulder.

Sorry I can't be more help. I don't have any experience with Iver Johnson firearms and the only reference I can find is a diagram in Jack First's parts catalog. It just lists the caliber as ".22."

Thanks Dave, I'll check it out with a short or long cartridge next chance I get.

Hi Wheelgunner,
I just finished a restoration on an I.J. Target Sealed 8 and yours sounds like it still has a problem. It is chambered for the .22 LR and should accept them without resistance. Examine the chambers very closely for the possibility that the gun has been shot extensively with .22 Short ammunition. This could cause a ring in the cylinder that may need to be removed before .22 LR ammo can be, safely/properly fired in the revolver.
As for the ejector system on this one... I carry a small screwdriver with a three inch by one eighth inch bit in my shirt pocket... <grin> That's about the best ejector one can find for this type of revolver. No ejector ment less expense for the manufacturer. When the Target Sealed 8 came out that was a major concern for I.J. Some of the more expensive I.J. pistols of the time had a better ejector system... <still grinnin'>

I've been around a Iver Johnson sealed 8 most of my 60 years. It has had the same problem you discribe for most of those years. In fact my Grandfather had a gun accident tapping shells into cylinder when I was a boy. I think you will find the firing pin has "peened" the back of the cylinder when it was out of time thus upsetting the metel in the area around each bore causing distortion of the bore.

This one really came back from the past....

As a follow up I had some old CCI mini-mags and on a whim tried them. They dropped right in the cylinder like they belonged there. I don't think ammunition shrinks, so I'm guessing the Remington and Federal cheap stuff I'd been using was a bit oversize. Works fine in my 22/45 and Marlin 49DL though.
