I am lucky that the one factory tube that I am running has no precevable stress....it does not string when it gets hot.
Now, if you have a tube that walks the shots in a certian AND REPEATABLE direction, you will need to wait....anywhere from 10 to 30 min depending on conditions.
My question...if you (not you spacificly.....you as in anybody with this problem) have a tube that walks it's shots...well...why do you still have that tube??? This is LR hunting, and a tube that walks it's shots has no place here. UNLESS...you NEVER miss that 1st shot at XXXX yards.
Just my .02,
I respectively disagree with you. What you consider long range may not be what us "newer" or "cant afford expensive rifle"shooters consider long range. Personally, I consider anything over 300 yards "long" range for me. SO that being said, a rifle shooting 1.5 MOA or less would work. I look for loads that shoot less than 1MOA. With 1 MOA loads you should be able to shoot to 500 yards or a bit more...that being said...yes these factory barrels can heat up and cause walking which is why someone like me who cannot afford HIGH end custom rifles
would care about how long to wait to cool off the rifle for cold bore shots. By the way...when I say 1MOA group I am looking for a 3 shot group with all 3 shots in less than 2 minutes which means follow up shots would be possible (at least 2 additional shots) with out worry about barrel walk.
