David Tubb Contour?

Re: David Tubb Contour?

I had a Rock barrel in a Tubb contour... It was a modified Med Palma I believe.

It was 1.200" at the chamber, tapered down to .940", and mine finished out at .855" to square up with a Bennie Cooley brake.

Hope this helps, I would get you better pics, but I sold the rifle...
 
Re: David Tubb Contour?

I just measured the bbl that came on my Tubb SpecTacLr. In the mid chamber area it is 1.220 tapering down to .820 then it's turned down to a sharp shoulder of .750 for the level or iron sights.

For what its worth, someone at Krieger told me their Tubb Contour was 1.2" from breach to 3.250", then tapering to .975" at 4.88", then tapering to .870" at 24" (basically a medium-heavy palma).

Edit
95LTZ: Any chance you could post more dimensions on your Tubb barrel?
 
Re: David Tubb Contour?

I have a few of these barrels, and I think the dimensions can vary.

A) .308 Win version:

Length = 25" (twenty five inches)

Muzzle Diameter = 0.875" at shoulder before turned section (for irons, at 0.750")

Diameter from breech to just before taper = 1.205" and this section is 2.5" (two and a half inches) in length before taper

Taper is Palma-like.

At 12" forward of breech, diameter = 0.940"


B) 6 XC version:

Length = 28" (twenty eight inches)

Muzzle Diameter = 0.895" at shoulder before turned section(for irons, at 0.750")

Diameter from breech to just before taper = 1.210" and this section is 3.5" (three and a half inches) in length before taper

Taper is Palma-like.

At 12" forward of breech, diameter = 0.955"

B) 6BR version:

Length = 25" (twenty five inches), excluding "bloop" tube glued onto the muzzle to extend sight radius (for irons)

Muzzle Diameter = 0.850" at shoulder before turned section(for irons, at 0.750")

Diameter from breech to just before taper = 1.210" and this section is 2.5" (two and a half inches) in length before taper

Taper is Palma-like.

At 12" forward of breech, diameter = 0.915"


 
Re: David Tubb Contour?

I measured the total length of the bbl which is 26.5".
The chamber area is 1.220 for 3.25"
5" from the chamber end of the bbl is .925
12" from the chamber end .895
 
Re: David Tubb Contour?

The three I mentioned are all Schneider type. I have a couple of others, one of which is Holliger-chambered/fitted if I recall correctly, but I don't recall which barrel maker he uses. (Holliger as in White Oak Precision/Armament...)

Tubb talks about his barrel contour/length selection in his excellent documentation on the T2K. See a portion of the printable manual here: http://www.davidtubb.com/tcom_images/t2k_images/t2k_specifications.html
