“It Hammers” — Radical Jennings-Stocked F-TR Rig Shoots Great

We recently reported on the new Jennings F-TR stock with integrated bipod. When we first saw this rig we thought, “OK, it looks cool, but how does it shoot?” Well, we had a chance to test a .308 Win F-TR rifle built by Chesebro Rifles using the Jennings stock, Barnard action, and 32″ Bartlein barrel. With the gun on the bench, we first shot a few rounds to confirm zero and test for function.

Then gun-builder Mark Chesebro set the rifle on the shooting mat, opened up a box of Federal 168gr Gold Medal Match (GMM) .308 Win ammo, and got down to business — from the ground. What happened next can only be described as “shock and awe”. Mark nailed three successive groups that left us shaking our heads in amazement. The Jennings stock works. Does it ever. This gun hammers.

All groups were shot from the ground, bipod-supported, with Federal factory GMM ammo.

Mark’s first three-shot group had two shots in one hole, then the third leaked a bit high for a 0.184″ group. Then Mark dialed down 2 MOA elevation, and drilled an astonishing 3-shot .047″ group. (For reference, the black diamond in the orange paster is 1/4″ from point to point.)

I was watching through a Swarovski spotting scope and I saw all three shots track into one hole that just got a little whiter in the middle with each successive round. I yelled out “Stop shooting!” because I wanted to measure the group. It was an easy mid-zero — and honestly it looked like just one bullet hole from a pistol. That is amazing with factory .308 Win ammo, particularly in a barrel throated for 185s, not the 168gr SMKs Federal uses in its Gold Medal Match .308 ammunition.

After measuring Mark’s 3-shot bughole, we walked back to the firing line and Mark shot a full 5-shot group. This would have been a two-flat, but he flinched a bit and his third shot went a little high to open the group to a 0.233″. Still darn impressive with factory ammo…

Editor’s Comment: This Gun is Ultra-Stable and Tracks Straight Back
I had a chance to shoot the gun from the ground. I can tell you this — the stock design really works. With the wide-track bipod, the gun is incredibly stable. As you’re aiming there is virtually zero horizontal movement in the crosshairs. All you need to do is squeeze the ears to set your vertical Point of Aim and pull the trigger. This thing is one of the easiest guns to shoot accurately (from the ground) that I’ve ever tried. You don’t have to struggle for stability at all — the gun wants to stay dead calm.

With the large, cylindrical Delrin feet placed on a mat, the gun tracks straight back. And there is no hop, no bounce, no roll. In fact, the gun tracked so well that I could see my bullets impact on the paper target. That’s surprising for a .308 Win with no muzzle brake. After a shot I could slide the gun forward and the crosshairs were right where they should be — the only thing I had to do is squeeze the ears to re-set my vertical. All I can tell you is the thing is very easy to shoot well.

I don’t know whether it is because of the forward-angle geometry of the legs, or the Delrin feet, or the properties of the carbon fiber tube that supports the front end, but the gun seems to have more damping than other metal-chassis stocks I’ve tried. Some metal-stocked guns seem to “ring” and transmit a sharp pulse to the shooter. This Jennings stock doesn’t do that — it seems to soak up vibration somehow. And the recoil is very mild, I think because the Delrin feet slow the gun down as they slide back smoothly.

Bottom Line: We came away very, very impressed with this rifle and the Jennings stock. I have never experienced a bipod-equipped rifle (in any caliber) that is easier to aim and hold steady, or which is easier to return to precise point of aim after each shot. And, without question, this is one of the most accurate .308 Win rifles we have ever shot from the ground. And that was with factory ammo, not tuned handloads!

Making a Great Design Even Better
Could the rifle be improved? Yes. While there is some rear elevation adjustment (via an eccentric bag-rider that rotates) we would like to see more rear-end elevation adjustment, so the gun could better adapt to uphill and downhill target placements. Also we’d like to see a higher mounting point for the bag-rider so you could use a taller, beefier rear bag. We discussed these points with Mark Chesebro, and he’s agreed to start prototyping some upgrades. This may include a thumbwheel-adjustable bag-rider (sort of like an upside-down adjustable cheekpiece). At our suggestion, the vertically adjustable bag-rider may be offered in two versions — straight and angled. With an angled bag-rider (i.e. with a slight amount of drop front to rear), you could adjust your vertical point of aim by sliding the gun forward or aft in the rear bag.

We will supplement this test report with more photos and video in a few days. We know you want to see how well it tracks. The video tells the story better than words can…

Chesebro Rifles Takes Over as Successor to MT Guns

After more than 60 years as a competitive target shooter and gunsmith, McLane (Mac) Tilton, proprietor of MT GUNS, is passing the baton to his chief gunsmith/machinist, Mark Chesebro. “Mark has acquired the assets of MT GUNS and will be its successor. I’m very pleased that Mark is establishing Chesebro Rifles and that he will continue to provide highest quality competition target rifles in the tradition of MT GUNS,” Tilton announced today.

Mark Chesebro Rifles

Tilton expressed his complete confidence in Mark’s ability to provide a seamless transition for MT GUNS customers: “He attended the well-respected gunsmithing course at Yavapai Community College in Prescott, Arizona, followed by four years with Bill Atkinson at H.S. Precision, where he perfected techniques in chambering and rifle smithing. After eight years of general gunsmithing in Everett, Washington and as an aerospace machinist, tool maker and CNC programmer, Mark relocated to Arizona, where he joined the team at Ruger. He came to MT GUNS in 2004 and we were very impressed with his inventive capabilities.”

“In 2006, Mark and his wife, Lisa, answered a call from their church to fulfill a three-year teaching mission in Ecuador. When he returned in 2009, he rejoined our team at MT GUNS and has continued to develop his innovative ideas and techniques, including the development of a press to insure perfect alignment when rebarreling Anschuetz rifles, as well as a centerfire conversion for BSA Martini rifles. He has also developed an entire system for converting the Anschuetz 54 action from a single shot to a magazine-fed repeater. Also, he’s mastered the critical alignment when bedding Vee-blocks for Barnard and Anschuetz actions.”

Chesebro Rifles will continue to build competitive Palma, F-Class, and Benchrest rifles using the Barnard action, as well as the very successful BSA and Anschuetz Rimfire Bench Rifles. Contact for Mark Chesebro at Chesebro Rifles is: info [at] chesebrorifles.com.

McLane Tilton and Bruce Duncan will still be available at MT GUNS for any customers with unfinished business.
