Part of the success story of the CheyTac weapons system is the fact that the heart and soul (the completed barreled action assembly) of the various models is manufactured at and by Lawton Machine, LLC of Dillon Montana. Barney Lawton designed the Model 210 action, and his barrels are top quality. Bench rest rifle building processes and techniques are used to thread, chamber, crown and install the barrel into the CheyTac 210 receiver.
Barney Lawton is a perfectionist and his actions and barrels are testament to that fact. I have built a large, and fast growing number of, barreled action assemblies using his barrels and actions. They have either been for our rifles, or we just build the barreled action assembly and the rifle is completed elsewhere, which is the bulk of our production.
Having said all of that, I'd like to add that they are the most consistently accurate barreled action assemblies that I have ever shot, period.
The CheyTac cartridges (408, 375, 338) are all fun for someone like me to shoot because they are so effective at extreme ranges. I believe that the longest one shot elk kill made by the shop personel is 1,528 yards with a 375 CheyTac cartridge. A green hand long range shooter (who shall remain nameless to hide his shame) made an attempt at over 1,600 yards last year to only watch the vapor trail of the projectile sail like a cloud over the back of the animal. No matter what, you never rush a long range shot. It is either there for the taking, or not.
