Barrel fitting question
« on: September 22, 2007, 05:55:54 AM »
Just got a nice barrel from Digger and am fitting it to my frame. I can get it to lock tight with a popcan shim but it still has some side to side play although I can't see light in the crack or fit a feeler guage in. So now what?

No. Forgot. Smoke the latch and close it? Will report back after I do that.

Okay, smoked the shelf and found that it looks just like the picture in the FAQ of proper latch engagement. I can pull up and down on the muzzle and the barrel seems tight, but it moves a bit if I push or pull laterally left and right.  Bed the underlug?

I suggest you go shoot it first.
 I know it can be annoying, but if it shoots well the end result will be the same. I have a couple that are like what you explain and they shoot just fine.

My used barrel fit really good when I first got it, but it did have that lateral motion ever so slight, but it was there.

I cleaned the lug area where the pin fits and rotates, and applied a slight amount of J B weld to the lug radius.

It doesn't take much, and I used pam to spray the pin, and inside around the pin on the receiver so as not to JB weld my rifle together, and closed the action, letting it sit overnight.

Next morning opened the rifle, took the forearm off, cleaned and greased the pin, and it's tight as a drum with no movement at all.

Looking at the lug after taking it apart I noticed the pin made full contact on one side with the lug, but the left side filled in nicely with the JB weld whch shimmed up the space, thus eliminating the play!
My culled down Handi's are the 45-70, and then I have a few others to keep it company...357 Mag/Max. .45 LC/.454 Casull Carbine, .243 Ultra, and 20 gauge Tracker II.

The slight looseness isn't dangerous, just disconcerting, as CW suggested, shoot it and see how it does, that old adage "if it ain't broke, don't fix it" can apply here. Make sure the stock bolt is tight, I had that happen once, thought the barrel was loose, but the stock bolt was the culprit, I could feel it, but couldn't tell where it was. :-\
