Available Calibers – blued Chrome-Moly or Stainless

Calibers noted above as "G2 only" are only available for use in the modern G2 actions, not the classic Contender and will be marked accordingly. This is for your safety due to potential pressure levels in these cartridges. Call us if you have any questions.

* Custom barrels chambered in 30-221/300 Blackout are designed and built to minimum chamber specs. These are handload-only chambers and will NOT accept once-fired and/or remanufactured brass.

** Custom barrels chambered in 7.62 x 39 will be built on a true .308" groove barrel. This does not allow for use of ANY re-manufactured or factory-built ammunition regardless of bullet diameter used. These products are commonly made for traditional military chambers with larger bore sizes or have been fired in oversized chambers and may cause damage to your firearm when used in our barrels. Our 7.62 x 39 barrels are intended to be handload-only.


*** Custom barrels chambered in 32 H&R Mag. and 327 Federal will be build on a true .308" groove barrel and not a 32 caliber pistol bore (.312" groove). This does not allow for use of ANY factory-built ammunition. Barrels in these calibers are intended to be handload-only.

‡ The 45-70 US Government when used in the classic Contender or G2 actions should be limited in pressures by utilizing original Marlin Model 1895 loading data.

How Do I Place My Custom Order?


First and foremost, we want to talk with you. While we prefer a phone call to go over the variety of details and options involved with every custom order, we are happy to work by email as well.

You should know that most orders do not require any deposit. Non-refundable deposits are required for all special order barrels, in the value of the corresponding "premium". Deposits are also requested for special order add-ons like G2 frames and scopes.

If you have any additional questions about our ordering and production system, please check out our page on The Custom Order Process.

Standard Barrel Profiles

Bullberry Contender/G2 barrels are most often made in a straight Bull profile. The Bull profile is considered optimum for both balance and accuracy in the already lightweight Contender; these also match the modern G2 barrels from T/C. If you prefer a lighter weight barrel for any reason just specify the details when ordering. Please note, however, that standard Bullberry tapers start 5 inches ahead of the breech to allow ample room for scope mounting using any manufacturer's hardware. The original Contender carbine barrel's muzzle diameter can be matched on your new custom barrel upon request. Other common tapers will feature muzzle diameters of .750" to .500" (in .050" increments), though this is dependent upon the barrel's bore dimension.

Optional Barrel Add-ons and Accessories

Muzzlebrakes, muzzle threading, sights and scope mounts are the most common additions to our custom barrels. Please visit our Accessories page for full options and pricing breakdowns on a variety of extras.


If you are new to the T/C break-actions, you may want to start with the Encore® or ProHunter™ if you are interested in larger calibers (higher chamber pressures) than listed above. The classic Contender® frames have not been produced since the 1990s, though you may find used Contenders on the market (many customers have found success on The more modern G2® is readily available again from our suppliers, after not being produced and sold new for more than 5 years. As always, we offer these frames for purchase as a courtesy to barrel customers, as availability allows. We do not purchase frames for inventory purposes.

Frame purchases include only the frame as a result of our wide variety of custom woodwork, laminates and synthetic options, and the inclusion of our hanger system on all our barrels.
