Rifle barrel life – How fast will your barrel reach retirement age?

In this age of increasing retirement age, it seems we’re expecting our rifle barrels to follow suit! In the world of high-performance rifle cartridges, barrel life maybe a short season. This month we look into rifle barrel life with 3 top gunsmiths on both sides of the Atlantic to get a shot at this highly energized topic amongst competitors, hunters and ELR shooters alike.

We spoke to three top gunsmiths in the game to find out how it effects competition shooters, ELR shooters and hunters, all after the ultimate performance for their intended game.

Advanced Carbon Fiber

ACCURACY, DURABILITY, LONGEVITY.

Check out the barrels here.

The aerospace-grade carbon fiber we use has a specific strength up to 30 times that of stainless steel and a specific stiffness up to 7 times greater than steel. But strength and stiffness are only part of the equation. Heat conductivity and thermal expansion are also of paramount importance when developing a match-grade carbon fiber barrel. Our helical wrapping pattern favors the longitudinal thermal diffusivity of the carbon fibers (along the length of the barrel) allowing them to more efficiently dissipate heat emanating from the barrel, rather than insulating it.

Because our barrels are engineered for thermal performance, they also move heat very effectively through the wall (thickness) of the barrel, greatly increasing heat transport and resulting in barrels that cool faster, live longer, and maintain accuracy over longer sessions of fire.
