Gunsmithing Barrel Set-Back question Sendero/Varmint contour

[GasLight]

Hello all,

I just picked up a custom kreiger take-off barrel chambered in .260. I am thinking hard about re-chambering to 6.5 creedmoor, but am wondering how bad it would look to take enough off the barrel shoulder to do this. The barrel shoulder will need to be pushed forward around .200" to clear a thicker recoil lug and the room to clean up the chamber completely. Has anyone else set back a varmint contour barrel this far? Does it look real bad?

Thanks

Dave

before you trip on your dick here.....mind telling how many rounds down the tube ?

just know it is low round count, am guessing less than 300, but that isn't a fact...

You thinking I should go deeper to clean up the throat area as well?

The difference in chamber is ~.0115" and I could go with a smaller recoil lug to freshen up the throat at .180" which takes 3 threads.

that would drive the reamer into the throat an extra ~.06" or so.

awe man....i would first shoot the barrel and see how it prints....then if you are set on the re-chamber....who the hell cares what it looks like if you got enough shank

I suppose I could leave it .260, but I am not set up to shoot that caliber, so was thinking the creedmoor would be a nice fit, but suppose I could put some money into .260 ammo first and she what she'll do.

Thanks

you must really like the .260 brass, trying to talk me into sticking with it... another guy on the line dropping precious pieces

The bolt is speakin with mighty wisdom. The .260 is really nice. I shoot the 139 scenars. Good luck!

Maybe I'm not understanding what your trying to say but adding a thicker recoil lug won't cause you to have to set the barrel back any more than a thinner one will. All you will have to do is set the barrel back enough to rechamber. You will be adding shank length to barrel with the thicker lug.

Yes, using a thicker recoil lug doesn't require me to trim any more of the bolt recess or threading, but it will require the barrel shoulder to be pushed forward, which is what will cosmetically make it look odd. That is my main concern with this thread, how bad does it look when you push the barrel shoulder of a Varmint contour barrel forward in the range of .200" or so.

Thanks

I have 3 rifles with .300 thick lugs and remington varmint contours and I don't think you will ever notice a difference in the looks.

How do you think your's would look if you took another ".116 off your shoulder? Would it be noticable? Thanks for the help.

No I don't. If you want I will email you some pics as soon as I can get the time. Probably this weekend.

Re: Barrel Set-Back question Sendero/Varmint contour

that would be cool. I guess I just need to see, but I don't want to start cutting 1/5" off the shoulder and end up thinking, WTF did I do that for? LOL

Thanks man

Dave,
I set barrels back between .118 and .125 regularly and it has no effect on how the barrel looks. Since you're using a Krieger, you don't have to worry about timing a roll mark, so take off what is necessary to allow a re-chamber and you'll be fine....
