Mr. Glenn has just completed bbl'ing my Wesson 44-77 this way. From experience, I won't have to use anything in the threads to keep it tight ! He has turned the GM #4 weight bbl to partial round and is mounting a Lyman 6X long scope that originally came with a Ruger #1 commerative rifle --- necessary for these tired ol eyes & it looks way cool.   Ken

Good morning, Board;

This thread seemed to get off to a slow start, but it's gotten good!  I appreciate the comments.

A couple of comments here have caught my attention, but first let me sketch a little background.

I compete with a Browning BPCR in .45-70.  Several months ago, I began to have to use more and more left windage to get a neutral sight setting.  So I set the rifle in a vise with the front bubble level and placed a machinists level on the action at the top of the "high walls".  The barrel had rotated to the left from the shooter's point of view.  It was clear to the eye even without the level.  I put a shim under the right side of the sight to lean it to the left and shot it that way for a while.

When i pulled the barrel, it was very tight and had about 0.006 of draw (a little over 1/2 of a flat).  In view of the recent comments in this thread about how little draw is needed to keep the barrel in place, what happened?

Y'all be good.

Mr. Horsefly:

I cannot even make a bad guess why your barrel turned. For that matter I cannot imagine it could turn that much with it having extractor issues. A barrel does not have to be much out of align to cause extractor problems.

A barrel with as much draw as you describe is something you cannot casually turn.  That is barrel vise and action wrench tight. And even if it were just hand tight it ain't a gonna move without some input. The only rotational force on a barrel is the torque reaction to the bullet spin, Howsomever, the Browning has a right hand twist barrel so if the barrel is inclined to move it is going to tighten. 

I can only assume that it is caused by the communists.

Good morning, Glenn;

My thoughts are just about the same as yours and I'm still scratching my bald spot about it.  I forgot to mention that I looked at the front sight and it had not moved.  The extractor did work just fine.  The rotation was enough that I could feel it in the way the stock fit my shoulder.

It may just be a communist plot..... or someone I shoot with.  Darned if I can see why though.  They usually beat me anyway.

If you do not use locktite, how much should a barrel pull up?

Y'all be good.

Maybe they used the rifle in question for that purpose, which could of course be the main cause??  Repeated, hard impacts on hard objects do tend to loosen up things...  Grin

Good morning, Mr. Belgian;

I think that's the only way I haven't been beaten recently.  Please don't give folks any ideas!  Some of them read this site, too.

Y'all be good.

Then again, this could have caused a loss of memory of the incident. As well as the aforementioned bald spot.

What does hot bluing do to the loctite?  Should the barrel and receiver be blued before final assembly?

Hot bluing (285-290 degrees) will loosen ANY locktite, Blue separate, them assemble.
