I,m just curious as to how many rifles have the barrels crooked in the action. I have had 2 and as luck would have it, they were both rugers
the 77/44 mag. the first one was a few years back from the first batch of bolt action 44 mag and it was barndoor accurate. the last one a month ago and I,m still waiting for the replacement. these pics tell the story. a straight cleaning will work and also lay the rifle flat on a table
to check for up-down crooked. I,m curious to see the ratio of crooked barrels in Canada versus the US. are the manufacturs shipping there
rejects out of the country??????"?

I don't know how many barrels might be crooked but I totally reject your "method" for determining such an occurrence.

Unless that rod is tight to the barrel ... and I mean TIGHT then it will be able to droop when placed in the barrel. As it interfaces with the rifling it could well be pushed off to one side slightly.

I can tell you that the bore rarely is 100% straight and that the bore rarely is 100% concentric with the exterior of the barrel and yet most rifles shoot fairly well. In the end none of that matters as long as the rifle shoots.
 
Very telling pictures. A "crooked" barrel is likely a bad chambering job. A chamber not square to the barrel. The barrel could also not be square to the action though you'd never see it. Crooked implies bent or twisted out of shape. Can you actually see that the barrel is bent? Is that piece of bar stock perfectly straight? No run out at all? I've never tried what you have pictured. Interesting, and unfortunate. Definitely answers the question as to why your rifle is barn door accurate if your method is not flawed. Enjoy your new barrel(s)...or perhaps have a gunsmith re-chamber your factory barrel and square the threads if you're convinced you have a problem.
 
Op, I'm not familiar with your rifle.
In the second pic, left side of steel rod, couple inches inside the action, there's a protruding block (bolt release, extractor??).
Is it pushing the steel rod to the right?
 
You'll not get a production rifle that's perfectly true. I make aircraft engine parts with +/- .002 on run out for most. That could translate to 1/4 to 1/2 an inch or more that your rod would be offset once you get 6 inches from the face/diameter that you're checking.
 
A crooked action face or a crooked bbl shoulder (crooked to the axis of the external dimension) is what makes a bbl screw on off kilter. Unless the action has been trued up and the bbl threaded and shoulder cut to be square with the external profile it will be off.

Even A really good re bbl job may not have the end of the bbl exactly straight as bbls are all bent at least a little. It's the first inch of the bore, chamber, threads and bbl shoulder being square to the action is what is important.
 
yeap..........looks flawed........the method your using to check that is.........

I have yet to see a bore run perfectly true to the outside profile of a barrel, some are very close but none are dead on, compound that with a receiver face that is a half degree off of being square to the receiver itself and you have yourself a perfectly fine production rifle, these rifles are of a fine quality, unlike most of the people who try to find faults with them because they can't shoot worth beans........the shooter that is....
 
Suspect you're seeing an optical illusion, but bar stock isn't straight or round anyway. If you think Ruger or any manufacturer is dumping "seconds" or substandard stuff in Canada, you're very confused.

this was the first run of 44 mag bolt actions some years ago and after sending it back to the factory, they told me they could not fix it and to pick
any rifle on there web site and they shipped me a new one. I guess they saw the optical illusion too. I guess they saw the same optical illusion in this last one
too as there shipping me a new one too. OBTW, I used 1 inch turned and ground shafting in the scope rings and at the end of the barrel I was 1 inch out.
 
Tell us the REST OF THE STORY! jbunny. You and I both know about the first rifle. Ruger was more than co-operative when they agreed to you picking out the rifle and model you wanted, which was a Ruger#1. You then promptly sold that rifle for a lot more than you paid for the rifle you said was defective. So I'm wondering WHY would you buy the same make and model rifle again and do the same checks again??????
 
Rugers in general are not noted for precision nor accuracy to start with but your method of determining what a 'crooked barrel' is - is flawed.

POST #4 nailed it - "Unless that rod is tight to the barrel ... and I mean TIGHT then it will be able to droop when placed in the barrel. As it interfaces with the rifling it could well be pushed off to one side slightly."
 
if the muzzle was a full inch off as mentioned in post #12, how was it able to sit in the barrel channel? I would love a pic of that, especially the walnut model.

Could be the rings off centre, or the slots where the rings sit...
 
LOL...I think the rod being off to the right side of the action is due to the coriolis effect in the northern hemisphere....if he was to take the same picture Down Under it would be off to the left side....:)

I share that view and do not own any Rugers even though I think the #1's are very elegant. Notwithstanding - I have seen Ruger .22 pistols that outshot MUCH MORE expensive target pistols and had a lot fewer alibi's than the highly regarded Walther GSP .... I have also seen a box stock Ruger 77 in heavy barrel .243W win an F class event in Ontario against some big shooters. So they do have their redeeming qualities!!
