Sunday GunDay: DIY 6mm Creedmoor with Howa Barreled Action
The 6mm Creedmoor has become one of the most popular cartridges for PRS/NRL competition, and it also works great in the varmint fields. Good Lapua Creedmoor brass is available, and there are many Creedmoor factory rifle options now, such as the Savage Model 110 Elite Precision with MDT chassis and the Ruger Precision Creedmoor with 26″ barrel.

Another smart, cost-effective option for 6mm Creedmoor fans is to build your own rifle, starting with a Howa barreled action. The Howa 1500 is a mag-fed, flat-bottomed bolt action that ships with the excellent HACT 2-stage trigger. Howa 1500 full-size barreled actions have been available with a variety of barrel lengths and contours, starting at $429.99 at Brownells. Howa 1500 Mini barreled actions are available starting at $399.99 at Brownells.
There are quite a few good stocks/chassis systems now offered for Howa 1500 actions, including the excellent KRG Bravo Chassis, which features an ergonomic composite outer shell over a precision-machined inner chassis.
Our friend Gavin Gear of UltimateReloader has built a nice Creedmoor rifle using a Howa 1500 heavy-barreled action and KRG Bravo Chassis. This project has proven very successful. The rifle has shown impressive accuracy and outstanding reliability. Gavin has used this rifle in some practical/tactical competitions, and it did well.
In this video, Gavin fits KRG’s enclosed fore-end to the KRG Bravo chassis. This accessory fore-end features a top Picatinny rail and various attachment options on the sides and lower section. Here you can see the enclosed fore-end (upper right) next to the factory forend included with the KRG Bravo (lower left):
Gavin then fits a Mystic Precision MPod from EGW. This stable, wide-base bipod uses a T-Slot rail for rifle attachment, and has legs that adjust independently for height. The video shows the rifle coming together step-by-step. This is something the average guy can do with simple tools — no gunsmithing is required, because the Howa barreled action is pre-chambered for the 6mm Creedmoor cartridge.
In the video above Gavin unboxes his Howa 1500 barreled action from Brownells. He then mounts the barreled action to the KRG Bravo stock, checking the torque levels. Next Gavin borescopes the hammer-forged barrel (5:55) noting: “What I saw I liked — there are practically no tooling marks. The finish on the lands and grooves looks really good”. Lastly, Gavin tested the trigger with his TriggerScan TS-11 (6:24), confirming a two-stage pull weight of about 2.25 pounds out of the box.
