Check out that 0.188″ group. Can you believe that was shot with factory .308 Win ammo? A couple seasons ago our friends at Criterion Barrels tested some .308 ammo from Creedmoor Sports. This was loaded with Lapua’s 175gr Scenar HPBT bullet. The results speak for themselves. Any time factory ammo can shoot inside quarter-MOA, that’s impressive. This ammo was used in a “Rem/Age” project rifle. That term refers to a Remington action rifle that has been re-barreled with a pre-fit Criterion barrel. The new barrel is secured with a Savage-style barrel nut. Hence the term “Rem/Age” or “Rem-Age”.

Criterion posted: “I think we may have a new favorite factory match load for the nitrided Rem/Age build.” Another reader added: “[Creedmoor’s] 175 Scenar .308 ammunition is top notch.” FYI, this group was shot on our load development target, which you can download for free from our Targets Page.

Why do Criterion barrels shoot so well? One reason is that Criterion’s barrel steel is carefully stress-relieved. In the photo below, Criterion Rack 1A (aka the “Coffin”) has been loaded with barrel blanks — made ready for the stress-relieving process.

Working with Pre-Fit Barrels
While they may require the purchase of some additional tools and a bit of a learning curve to install, using Rem/Age pre-fit barrels offer advantages over gunsmith chambering and barrel-fitting. In this video, 8541 Tactical explains how to install a Criterion 6.5 Creedmoor “pre-fit” barrel. You save money and time — you don’t have to wait for a gunsmith to chamber the barrel. While Criterion recommends that a competent gunsmith oversee the pre-fit installation, if you understand the use of go/no-go gauges and you have a barrel vise and action wrench set up to remove the original barrel, putting on a pre-fit barrel CAN be a DIY project. You don’t have to pack up your rifle to ship it off to a smith.
