If one had a tube done with the recoil lug machined integral with barrel, What would be the minimum functional dimensions required for that lug?

For the sake of discussion, I would say that depended on the chambering.

However, even on a hefty kicker I bet it could be quite a bit thinner provided it was properly bedded. As long as the bedding goes up to the shoulder the lug will have to shear off, I would suspect the stock would get quite hammered before that happens.

Is there a reason you are asking about this? I'm curious..

The factory lug is .187. you could make it .375. This would allow you plenty of room for any possible screw ups without endangering the lug. You could always machine the integral lug off and fit a separate replacement anytime you needed. I would make it thicker than stock.

If the recoil lug was an intergral part of the barrel how would the barrel be screwed into the receiver? The lug would have to be set exactly right in relation to the the threads. Also sounds like an expensive proposition.

He would just screw the action on as usual without having to mess with a separate lug. That would aleviate that problem if it were one. the problem would be or could be of missing the alignment and having to spin it around again. at .016 per turn it wouldn't take too many accidents before you ran out of 'lug'. And like b said that would be pretty expensive to produce such a barrel and you would waste a lot of material.

I think your math is a little bit wrong. .016" per revolution is a VEEERRRRY fine thread. The correct number for a 16 TPI thread is .062" per turn.

It ain't that big a deal to get the lug timed correctly; only takes a bit more time.

.016 would be 64 TPI. I was actually thinking .062 and 1/16 and erroneously combined the two. thanks for waking me up.

No it wouldnt be a big deal but if the person doing the job screws up its another .062 off the lug.

If one can index a barrel for m70 extractor claw cut without too much trouble, it can be done for a rem700 integral barrel recoil lug.
Probably with shallower depth,but thicker(.250").
Logic would tell me you fit&chamber the barrel, then finish machine the lug to final dimensions.
I cannot see where the stuffUp would come, unless one chose a riflesmith that didnt really know what they were doing to begin with.

Cost?.. well a number of folk fit Jewell triggers($200+)upgrade stock easily $600+ fitted,special coatings $250,.. which some may also consider mostly unnecessary for hunting.
My form off seemingly unecessariness is an integral recoil lug on top of the price of the new barrel one would buy anyway.

Yes, although rem700 is an economy manufactured unit,I believe it still desrves more than a cheap recoil plate,especially if building something like an up spec Ti rig.

I think Pacnor can supply a larger dia. blank (1.50"++) for the job, other wise, any quality recommendations?

Hey Woodjack, It seems to me than unless you have that Integral Recoil Lug "completely around the barrel" that you would experience a strange "Warp" of the Chamber as it warmed up.

Just speculation!

You would think.

You could do it that way, but I would prefit everything first and save the chamber for last.

It doesn't take much of a distraction to screw up a fit. Those who say they haven't experienced that at one time or another are only fooling themselves. Good luck!

Westpac, imsure there are people out there who plan to stuffup... and are 100% successful at it!

Hotcore,

The top end barrel makers often do integral features that dont go 360deg. around the barrel.http://www.martiniandhagngunmakers.com/actions.htm
If doing a smaller low recoil round;250sav,260rem, 270win?, one could make the lug not much more proud than the mount block you see in the last image.
