Mysterious Cause - Barrel Misalignment in Stock

[Phil3]

I am normally so fastidious and a perfectionist, I don't know why I "dismissed" the subtle gap. I am trying to learn machining, now equipped with a lathe and mill in my shop, and TWO mentors told me the same thing. "It doesn't need to be perfect, just within specified tolerances". My ex-boss told me, "Do not let the pursuit of perfection interfere with satisfactory progress". This is difficult for me, and I'd be the guy that would lose money as a gunsmith because I'd probably take a whole day to chamber a barrel! Despite that, I somehow blew right past an obvious problem. Not again!

Thanks for the kind words on the new grand kid.

Phil, if you're doing it for fun dont stop at "within spec". This is especially good advice building target rifles. Need to know when a guy says "good enough" if he is talking about target or hunting rifles.

Do you think this barrel fixture needed to be this thick? Il sure its beyond "good enough".

Its sure beyond good enough but extends the barrels you can chamber by at least 6”! But you can sure bend a barrel right where you want it with that!

Good guess but wrong. It is big in diameter but as short as possible. The set screw is just past the end of the spindle. Being able to chamber a shorter barrel is the reason I needed to make a new one.

I know how to bend a barrel and how not to.

I am the OP, and said I would reply after my daughter had her baby. Well, that happened yesterday

... and the rest is small cheese. Congratulations, grandpa.

I know this thread is old, but am the OP, and thought I would say what happened when I got the stock back from H-S Precision and their conclusions about it. They said it passed all their tests, and even included photos of the stock with their test set up showing it perfectly aligned. I put my barreled action back in the stock, and it actually seemed a bit better, but the barrel is still slightly off to one side. I think the improvement is due to the previously mentioned piece of tape no longer trapped between the recoil lug and action (or nut...I can't recall which now). But, the barrel is still off to the same side as it was before. I have an idea why, and will ask about this in a broader sense on another post in the "Main Message Forum" that I will write after posting this.

My guess is the threads on the Tenon are not correct.

Been watching this thread for a while and had similar problem. Had an action rebarreled to a little bigger sized barrel and after doing some very light channel sanding the barrel kept wanting to go to one side of the channel. Never really could find the problem or totally fix it. I think L. Sherm nailed it. Only thing that makes sense to me on this misalignment problem.
