Overview

A cut-rifled .30 caliber match blank in the contour and twist your build needs

The Bartlein .30 caliber stainless barrel blank is a single-point cut rifled 5R match blank for a gunsmith to chamber, thread and crown for your bolt action. It is offered in nine contours, 1:9 or 1:10 twist, and 26" or 30" lengths by contour. Any cartridge on the .30 bore can be chambered in it, from .308 Win and .30-06 to .300 WSM, .300 Win Mag, .300 PRC and .300 RUM.

Single-point cut rifled and hand lapped

Bartlein uses single-point cut rifling only, never a button, and hand laps every blank when it is finished. The .300" bore and .308" groove are Bartlein's standard .30 caliber dimensions.

5R rifling, five lands

Five lands means no land sits directly opposite another, and the land sides are angled instead of the 90 degree corner of conventional rifling. Bartlein says the jacket distorts less on the jump into the rifling, and rates 5R at up to 5% less BC loss from jacket deformation.

Nine contours, 3.60 lb to 6.9 lb

From the #2B Medium Sporter at 0.630" muzzle and 3.60 lb, through the #3, #3B, #4, #13 Varmint, #14 M24/M40 and #11 and #12 Palmas, to the #7 MTU at 0.930" muzzle and 6.9 lb. Weights are Bartlein's at chart length.

Two twists: 1:9 and 1:10

Every contour and length on this page is offered in 1:10, and every one except the #2B Medium Sporter is also offered in 1:9. Pick the twist for the bullets you plan to run.

Ships 1" longer than the length you order

Bartlein makes every blank 1" over the chart length so the gunsmith can cut the bell mouth off the muzzle and crown it. Lengths on this page are 26" or 30" finished.

Suppressor muzzle diameter

Bartlein recommends a 0.700" muzzle minimum under a suppressor and prefers a Medium Palma or heavier. Every contour here meets the minimum except the #2B (0.630") and #3 (0.670").

Fitment

Will it work with your build?

Works with

  • Every .30 caliber cartridge: .308 Win, .30-06, .300 WSM, .300 Win Mag, .300 PRC, .300 RUM
  • Bolt action rifles, once a gunsmith has chambered, threaded, crowned and fitted it
  • Suppressors on the #3B and heavier contours (0.700" muzzle or larger)
  • Muzzle threads of 1/2x28, 5/8x24 or 3/4x24, cut by your gunsmith

Will not work with

  • Any rifle as shipped: this is a blank, not a pre-fit or drop-in barrel
  • Pre-fit or gas gun installs: Bartlein makes no pre-fit or gas gun barrels

Gunsmith fitting and a flat shipping charge. This blank must be chambered, threaded, crowned and installed by a certified gunsmith. Rifle barrels and barreled actions ship for a flat $14.95 per order regardless of quantity and do not qualify for free shipping.

Detail

Fitting it and the fine print

Which contour and length do I order?

Match the contour to the barrel channel of your stock or chassis and to the weight you want to carry. Breech diameter is 1.200" on the #2B, #3, #3B, #4 and #14, and 1.250" on the #7, #11, #12 and #13; your gunsmith turns the shank to fit the action. Bartlein's view is that a heavier barrel resists moving as it heats, but that is mostly a button-rifled problem, because cut rifling puts no stress into the blank, so a lighter Bartlein contour gives up less than you would expect. For a suppressor, Bartlein recommends a muzzle of 0.700" or more, which is the #3B and up, and prefers a Medium Palma or heavier.

The length you pick is the finished length. Bartlein's chart length is 24" for the #2B, 30" for the Palmas and 26" for the rest; the 26" #2B and the 26" Palmas here are Bartlein modifications of those contours. Other contours are available to order.

What does 5R rifling mean, and does it matter for .30 caliber?

Bartlein offers three rifling styles: 4-groove, 5R and Conventional-5, all single-point cut. This blank is 5R. In 5R the bore has five lands, so no land sits directly opposite another, and each land meets the groove on an angle instead of the 90 degree corner of conventional rifling. Bartlein says the bullet jacket distorts less as it enters the rifling, and quotes testing that puts BC loss from jacket deformation up to 5% lower.

Bartlein also says the style or number of grooves has no real bearing on accuracy or barrel life. Their one exception is light-for-caliber, short-jacket bullets in .224 (35 to 60 gr) and 6mm (65 to 68 gr), which they say do not like 5R; that exception does not cover .30 caliber bullets.

Why does the blank arrive an inch longer than I ordered?

Every Bartlein blank is hand lapped after rifling, and lapping can leave a slight bell mouth at both ends. Bartlein builds a minimum 1.0" muzzle cut into the blank profile so the gunsmith can remove it when cutting to length and crowning. At the breech, chambering takes the bell mouth out on a centerfire blank, so nothing extra is needed there.

What voids the Bartlein warranty?

Bartlein lists three things. Fire lapping, including any compound made for it such as Tubb Dust. Any abrasive compound in the bore or on a brush, including Iosso, Witch's Brew, JB Bore Polish (red), Thorroclean, Flitz and CLR. And a brush on a drill run back and forth through the bore.
