Detailed Description

Ruger American 300 HAM’R® Match Barrel Conversion kit

To satisfy the demand for a 300 HAM’R® bolt action rifle we developed this easy caliber conversion kit for owners of the Ruger American rifle chambered in .223/300 BLK.

These match-grade stainless steel barrels are precision button-rifled, fully pre-chambered, and finished in matte black Armor-Tuff.

The 300 HAM’R®

The 300 HAM’R® was developed with one thing in mind, OPTIMAL TERMINAL PERFORMANCE. It offers near .308 Winchester effectiveness on game animals with amazing accuracy and low recoil in the lightweight and compact WC15 platform.

Terminal performance testing on over 2000 Texas feral hogs and various game animals as large as 800 pounds has proven it to kill much more effectively than the 6.5 Grendel, 6.8 SPC, 7.62×39, or 300 Blackout. Due to the optimization of bullet weight to barrel twist, accuracy has proven to be outstanding. Sub one-inch groups are the norm with multiple bullet choices for varying applications such as hunting, target shooting, and tactical use.

Undoubtedly the 300 HAM’R® will be compared to the popular 300 BLACKOUT or 7.62×39 and as the comparison charts below indicate, the ballistics of the 300 HAM’R far exceeds the 300 BLACKOUT and 7.62×39 in both velocity and energy when utilizing 95-150gr bullets.

300 HAM'R Comparison Charts

Kit includes

  • 16” 300 HAM’R® Barrel, 1-15 twist, Black Armor-Tuff
  • Barrel Nut, Black Armor-Tuff
  • Barrel Nut Wrench attachment for 1/2" torque wrench
  • Go-Gauge

*Installation should be performed by a gunsmith who is adept at removing Ruger rifle barrels. A barrel vise will be required to remove the original factory barrel/nut.

*Wilson Combat 300 HAM'R Conversion Kits will fit Ruger American models manufactured since 2018. Models manufactured prior to 2018 are not compatable with this kit.

Installation Instructions

With the original factory barrel/nut removed, thread the new barrel in place until there is a slight drag fit against the supplied Go-Gauge when closing the bolt handle. Once you have a light drag fit on the Go-Gauge, proper headspace will be set. A bolt that is hard to close on the Go-Gauge will indicate too-tight headspace.  A bolt that closes very easily indicates excessive headspace.

Once proper headspace is set, install the supplied barrel nut on a lightly greased barrel shank using the supplied barrel nut attachment tool on a torque wrench. Tighten barrel nut to 50 ft-lbs of torque.

3/4 inch groups at 100 yards is no problem. Hitting 3" steel plate at 200 yards is just as easy. Great product.
Super Performance
Starting with Bill's load data, I quickly found accurate loads for this rifle. A great benefit to this rig is that it is producing 100 fps higher velocities than expected. It'll put five 135-grain Sierra Hollow-points under a half inch at 100 yards. Several other load combinations produce sub-MOA groups, too. AWESOME!
fucking Awesome
You guys always seem to be several steps ahead of the rest of us !!!!! Great work Fly
Exactly what I was hoping for
Delivered quickly. Not packed the best, everything was rattling around in the box, no damage to anything though. Everything looks as shown in the photo. Quick, easy install. Dropped right into a Ruger American Ranch with no issues. Shoots amazing groups just like my 300 Ham’r AR.
Everything you need in kit.
We converted two Ranch 300 Blackouts with these barrels. There were no problems. Accuracy with 130 load for AR was about 1”@100. Didn’t need to develop further for my hunting purposes. PA whitetail and TX hogs. Highly recommended.
