Exclusive Interview: Frank Green Of Bartlein Barrels

If you have ever thought of getting involved in precision shooting, or are already immersed in the Precision Rifle Series competition, Bartlein Barrels is an industry name to know. Frank Green, Tracy Bartlein and Andy Kihn, who all previously worked for Kreiger Barrels, founded Bartlein Barrels and built it into what many are familiar with today – and for good reason. Green sat down and gave us the ins and outs (pun intended) of their process and concepts of what makes them one of the best in the industry.

Here's an excerpt of the questions that were asked: ASJ What types of barrels do you offer?

FG We offer chrome-moly steel (CM 4140) and stainless steel (SS 416R).

ASJ Which steel do you think is better?

FG Neither, from what we can see. If we had to pick one, we would lean towards the chrome-moly, possibly because it lasts longer, but how long a barrel lasts is subject to many variables: type of powder being used; how it is being shot and cleaned; types of bullets being shot, etc.

ASJ People often ask what “T-style” rifling is. Can you explain that?

FG We call it transitional rifling, but some refer to it as either gain twist, progressive twist or incremental twist. We can cut virtually any twist into a barrel, subject to tooling, of course, and we can start the twist at 1 in 14 and end up at 1 in 7, and have it uniformly increase from the breech to muzzle. We can also increase it very slowly, say, from 1 in 7.5 at the breech to a 1 in 7 at the muzzle. Read the rest of the Precision Shooting interview here.
