To Begin

  Tapers: Standard "Factory Taper" matches original TC factory Contender carbine and pistol barrel contours. Muzzle diameter depends on length. A 21" barrel will have .625" diameter muzzle. The "Non-Tapered" matches current G2 bull barrel contours (and forends) which is a straight .810" diameter bull barrel contour. This "Bull Barrel" contour is also the same as the original "Super 14" barrel contour.  Bull or tapered forends Click Here!
  Lengths: We make Contender pistol barrels from 9-15" long and rifle barrels from 17-26" long. Nothing in between.
  Forend Screw Positions - By popular demand barrels over 17" will have the factory standard 2-Screw carbine forend set-up. 9-15" barrels will have the factory standard 2-Screw pistol forend set up.
  Single screw or any other set up must be specially ordered at extra charge.
  Twist Rates: Standard EABCO rifling twist rate unless otherwise specified. Available twist rates are listed below.
  Estimated Delivery: Approximately 6-12 Months. "Custom" can have unpredictable delays... This is a best estimate.

Why We Offer Custom Contender "Accuracy" Barrels...

  There are three reasons why customers come to us for a custom Contender barrel: The first two are either to get a different chambering or a different barrel length than standard factory barrels.  
  But the THIRD REASON is to achieve a better potential for accuracy than mass production factory barrels... And, this is why we make our own EABCO "Accuracy" Barrels. Its not magic... just extra attention to the details that result in superior accuracy...
  Precision Barrel Blanks - An EABCO barrel blank is precision gun drilled from the best Chromoly and Stainless steel alloys. Bore dimensions are reamed consistent to airgauge within .0002" (2/10,000ths) of proper bore dimension. These are then Two-Pass button rifled in the various twist rates we offer to suit particular accuracy requirements.
  One at Time Barrel Making - True, center-to-center barrel turning at a rate that minimizes stress while keeping the bore in the middle. True, center-to-center chamber reaming insures centering and linear alignment of the chamber with the bore. Each chamber's headspace is checked and confirmed with gauges. True, center-to-center 11 target crown, applied after finishing, insures that bullets exit the barrel with perfectly even gas pressure.
  Chambers with Accuracy Potential - Cartridges that work well within the TC Contender's capability to handle pressure, bolt thrust, and extraction. It stands to reason that cartridges which operate on the outer edge of a gun's capability will have less accuracy potential than cartridges that operate closer to the gun's sweet spot. The TC Contender (and Contender G2) has superb potential for accuracy with the cartridges we chamber.
  PPC EABCO - Standard chamber that works best with handloads on Lapua brand brass.
Prices - Lengths Up to 26", Approximately 6 Month Delivery Time

Other Chambers and Non-Eabco Barrel Blanks
 If you want a chamber that's not listed here, keep in mind that for the accuracy reasons explained above, we don't do any heavy magnum chambers. Regarding blanks, we get the accuracy we desire from our EABCO barrel blanks. So, we do not substitute others.

Accuracy Proof Testing Service
  The prices above include the barrel and the precision workmanship described. These prices do NOT include the cost of trips to the shooting range, hand loading, and benchrest group shooting to provide an accuracy proof tested target, proven ammo, or handload data. That's the fun part for shooters but its time consuming and expensive for employee(s). If you would like to have this done for you, order our Accuracy Proof Testing service. It's performed at our shop rate of $65 per hour. Your barrel will be bench rest fired for accuracy at 100 yards and will be shipped with load data and proof target. This can get pretty expensive and slow down delivery... Call for info.

Choosing Your Twist Rate - See More at our Twist Rates Tech Report
  We have standards we recommend for various chamberings so you don't have to figure this out yourself. But if you'd like to know some guidelines and reasons, here they are: 17 Caliber: Use 1:9 for the rimfire and centerfires. 22 CF (Centerfire): 1:7 is only for the heaviest bullets. 1:12 shoots 40-50gr bullets accurate in 223 and up to 55gr, accurate in 22-250. 1:14 is only for the lightest bullets. 6mm/.243: Use 1:8 for 90-100gr bullets. 1:10 for 75-85gr. Use 1:12 for lightest bullets (ie. 58gr in 6PPC). On 30 calibers, a 1:10 twist is the best all-around. We DO build a few 30's in 1:8 twists for folks who shoot the heaviest bullets. The rule of thumb with twist rates is this: It is better to err on the side of too fast of a twist than too slow.

What to Consider When Choosing an Accurate Cartridge

 With so many choices, folks will often ask what we recommend as the "Best Cartridge". Unfortunately what's best for one situation is not best for another. For example, 6mm PPC has won more Benchrest Shooting Competitions than any other cartridge (I think)... so it should be considered as among the most accurate cartridges in the world. But it's a little light for deer hunting. As a contrast, our 308 Winchester chambering is what the US Rifle team used at the Bisley matches in England... very accurate and powerful enough for deer sized game and larger. BUT, it recoils significantly harder than the 6mm PPC... Making it a more difficult cartridge to shoot well. When recoil gets stiffer, accurate shooting depends more and more heavily on the shooter's marksmanship skill. So, the key to choosing the Best Cartridge for YOU is this: Decide what you're going to use it most for, then choose based on accuracy potential and shootability.
  Decide What You Are Going to Use it For - If you're primarily wanting to shoot the tightest groups at paper targets, choose 17 Ackley Hornet, 22 Hornet, 222 Remington, 223 Remington, 22 PPC, 219 Donaldson Wasp, 6mm PPC, 6mm Donaldson Wasp, 6mm BR. If you want to use it for Varmint Hunting, any of the above would be fine plus everything else we offer from .17 caliber thru 6mm. For Big Game Hunting, you need a medium to large case capacity with a heavier bullet in calibers from 6mm on up. Be careful here to optimize your choice for what you plan to hunt most often... not for the heaviest game you'll ever hunt. Most good deer cartridges will work just fine for elk hunting when loaded with heavy, bonded core bullets. But, the biggest magnums suitable for elk hunting are usually way too much for deer and a lot harder to shoot well because of recoil.
  Accuracy Potential - Cartridge Efficiency is something to consider in accuracy choices. If a cartridge is so large that it can't burn all of its powder charge by the time the bullet leaves the barrel, you'll get a lot of muzzle blast for not much increase in velocity and perhaps an accuracy disruption just as the bullet exits the crown of the muzzle. 7mm Ultimate Silhouette (7 US) is more efficient than 7-30 Waters when shooting 120-140 gr bullets. But 7-30 Waters will give a faster velocity when shooting heavier 160-175 gr bullets. Ackley Improved (AI) and Bench Rest Magnum cartridges will generally give a boost in both velocity AND accuracy potential due to the bolt thrust reducing body taper. 
  Shootability - Accurate shot placement is more important than velocity, energy, momentum or any other measure of lethality when hunting game. More importantly, it is a measure of your marksmanship that the pure accuracy of your barrel cannot overcome. So, it's important to choose a cartridge you'll feel comfortable enough with that you'll enjoy shooting it... for practice or just plinking for fun. Recoil and muzzle blast are the biggest destroyers of shootability because they cause a shooter to develop bad habits... flinching, jerking the trigger, holding the gun apprehensively, etc. As a direct recommendation on cartridges for deer hunting that have moderate recoil and excellent shootability, consider: 6mm BRM, 25-35 AI, 6.5mm BRM, 7-30 Waters, 7mm BRM, 30-30 Win, 30-30 AI, 300 BRM, and 375 Win.
  Killing Power for Sport Hunting - There's an excellent article in the P.O. Ackley Handbook Vol I that addresses this from all of the popular viewpoints (energy, momentum, velocity, knock-out, etc.) No one formula predicts perfectly for every cartridge but, what becomes most conclusive toward the end of the article is that being able to hit what you're aiming at is the first priority, followed by the quality of the bullet with respect to penetration and expansion.
