Derek Rodgers Sets Pending 1000-Yard F-TR Record

Derek Rodgers F-TR 1000 yard record McMillan stock berger bullets lapua brass

Derek Rodgers, the only shooter to win both the F-Open and F-TR National Championships, has done it again. While shooting the Santa Fe Trail LR Regional match in Raton, New Mexico, it looks like Derek set a new 1000-yard record. Derek nailed his 1000-yard target, recording a 200-14X score — that’s twenty (20) shots for record, all tens with 14 in the X-Ring. Derek told us: “Yesterday at Raton New Mexico’s Whittington Center, I shot a 200-14X, which should be a new pending F-TR National Record at 1000 yards.” Derek took special pride in this accomplishment, as he held the F-TR record before: “I’m happy to have the record back. I have had three of the last four records”. Well done Derek!

Derek Rodgers .308 Win F-TR Rifle Equipment List:
McMillan Xit stock, Kelbly Panda LBLP action, Bartlein .308 Win barrel (32″, 1:11.25″ twist), Nightforce NXS 8-32x56mm scope. Note that Derek shoots right-handed, but with a LEFT BOLT. This allows him to stay in position better while cycling the bolt with his LEFT hand.

This impressive performance by Derek shows that the best F-TR rifles can rival the big F-Open rigs for pure accuracy, even though the favored F-Open chamberings, such as .284 Win and .300 WSM, are still ballistically superior to the venerable .308 Winchester used by nearly all F-TR competitors. For his record-breaking load, Derek used Berger 200gr Hybrid Target bullets in Lapua .308 Win (small primer pocket) brass, pushed by Hodgdon Varget powder.

The Color Purple — A Father’s Gift to His Daughter

Erik Cortina 6.5x47 Lapua F-Class Rifle Daughter

“My daughter’s favorite color is purple, so I built her a purple rifle….”

Here’s a feel-good story about a family that shoots together, and a dad who did something very special for his daughter. All fathers create things for their children, but it’s unusual to find a Dad who has the skills (and motivation) to build a top-level competition rifle for his child. Our friend, Erik Cortina, did just that. Here is the story of the lovely purple maple F-Class rig Erik built for his girl Amberleeana.

My daughter would always tell me when I would go to a match, “Remember Dad, only Xs matter, the other stuff on the target is just there for decoration!” — Erik Cortina

A Father’s Gift: An F-Classer for Amberleeana

by Erik Cortina
My daughter Amberleeana has been wanting to shoot F-Class for a long time because I have been dragging her to matches since she was a little girl. She would come into my reloading room and watch me reload while she asked a million questions, all which I tried to answer to the best of my abilities. At age 9, she started hunting with a semi-custom rifle her grandfather gave her, a 6×47 Lapua built on a Remington 700 action with a Bartlein barrel. She has been very successful as a hunter so she decided to move to the next step and start shooting F-Class.

She shot my backup rifle before and she really enjoyed it. Here’s a YouTube video from a while back. This shows Amberleeana, at age 11, shooting at 500 yards for the very first time. You can see she does very well.

After hearing about the U.S. F-Class Under 25 (U25) Rifle Team selection trials in Raton this upcoming summer, Amberleeana wanted to try out for the U25 Team. I told her that was OK, but we had to modify the rifle she was currently using so that it could fit her better. After some consideration, I decided instead to sell that rifle and build her a brand new one.

Her favorite color is purple, so I built her a purple rifle with adjustable cheek piece and butt pad. Shurley Brothers (Austin, TX) crafted the stock from maple, and then applied a purple gloss finish. We think it turned out great. Amberleeana is eager to take the rifle to Raton this summer: “I would like to make the Under 25 U.S. Rifle Team and compete at the F-Class World Championship in Canada in 2017. My main focus now is on the upcoming team try-outs in Raton, New Mexico.”

I hope that my daughter enjoys F-Class as much as I have, which will allow us to spend more time together on the range and in the reloading room.

6.5×47 Lapua Load Development
The purple rifle is chambered for the 6.5×47 Lapua cartridge. Our preliminary load work up shows great promise using Vihtavuori N140 powder, 136gr Lapua Scenar bullets, and CCI 450 primers. We tried a variety of charge weights, starting at 35.7 grains of N140 and ending up at 38.2 grains. The photo below shows an initial series of 3-shot test groups at 120 yards. What do you think is the best node? What charge weight would YOU select among these? [Editor: That final load of 38.2 grains looks very good, but we would want to check for pressure signs and repeat with 10-round strings checking for ES and SD. Also, if you go by the vertical only, the 36.0 and 36.3 loads are worth further testing.]

Chuck’s Dazzling Dasher Duo — A Pair of Beauties

Forum Member Chuck L. (aka “Ridgeway”) has created a handsome duo of 6mm Dashers for competitive benchrest and varmint matches in Pennsylvania. Both guns are built on Kelbly Panda RBLP actions, with Bartlein 8-twist barrels, and Shehane Laminated Tracker Stocks. However, the two rifles are not exact twins, as you can see. One, which we’ll call the Big Dasher, is built on a Shehane ST1000 Tracker stock. The other gun, the Small Dasher, sports Shehane’s “Baby Tracker” stock — a design used with great success by Richard Schatz. The Big Dasher, optimized for 1000-yard competition, also has a slightly longer freebore — 0.136″ vs. 0.104″ for the Small Dasher.

Chuck tells us: “I don’t get out shooting competition as much as I want due to time and family, but when I do compete, I shoot a Groundhog match at Southfork Rifle Club in Beaverdale, PA. Info on Southfork Club events can be found at Southforkrifleclub.com. The Southfork match is basically a 100-, 300- and 500-yard match with one sighter the entire match and 5 shots at each yardage for score. The Small Dasher, with the shorter ‘Baby Tracker’ stock, was set up for the Southfork Rifle Club’s ‘Light Unlimited’ class which has a 13.5-lb max weight.” (Editor: ‘unlimited’ is a misnomer for a weight-limited category.)

Chuck adds: “The Big Dasher with the heavy ST-1000 stock is set up for 1000-yard benchrest matches in Light Gun class. I hope to shoot a couple 1K matches with it at Reade Range in southwest Pennsylvania. I am still in load development for this rifle since it was just finished in January. One ironic thing is, it shoots the same load I’m shooting out of the lighter gun rather well. The only difference between the two chambers is the freebore is roughly thirty thousandths longer on the 1K gun (Large Dasher). I will also shoot this at Southfork in the ‘Heavy Unlimited’ class.”

6mm Dasher Shehane duo

Specifications for the Dasher Duo:

Small Dasher (13.5-pounder): Chambered for 6mm Dasher with approximately .104 freebore and a .264 NK. (No way of knowing exactly since it freebore was done in a separate operation by Kelbly.) Components are: Shehane Baby Tracker stock, Kelbly Panda RPLB action, Bartlein 1:8″ LV barrel at 26 ¾”, Kelbly Rings, Weaver T36, Jewell trigger. The barrel was chambered by Kelblys and the stock was bedded, glued and balanced by a shooting buddy (Forum Member johara1). I clear-coated the stock with auto urethane. Total weight is 13 lbs., 4 ounces.

Big Dasher (1K Light Gun, 17-pounder): Chambered for 6mm Dasher with a .136 freebore and .264 neck (PTG Reamer). Components are: Shehane ST-1000 stock, Kelbly Panda RPLB action, Bartlein 1:8″ HV 5R barrel at 28″, Shehane +20-MOA rings, Nightforce NXS 12-42x56mm, Jewell trigger. The barrel work, pillar installation, and bedding was done by Dave Bruno. The stock was clear-coated by Chuck with auto urethane. Chuck also made the rear butt plate and balanced the rifle. Total weight: 16 lbs., 13 ounces.

Dasher Case-Forming: Neck-Turn then Fire-form with Bullets Hard in Lands
To fireform, I turn my cases down to fit the chamber and stop where the false shoulder makes snug contact with the chamber. Fire-forming rounds are loaded up with a 29-grain charge of H4895 or Varget and a 108gr Berger bullet seated hard into the lands about 0.020″ past initial contact with the rifling. It takes about three firings to make a nice clean Dasher case with a sharp shoulder. I anneal about every 3-4 firings. I have many cases that have about 10+ firings on them and they are still shooting well. The primer pockets are a little looser, but still hold a primer.

Both Dashers Group in the Ones at 100 Yards
My main bullet for both rifles is the 107gr Sierra MK, loaded with Reloder 15 powder, Lapua cases and CCI 450 primers. My main load for the Small Dasher is 33.0 grains of Reloder 15. This load shoots in the ones at 100 yards. For the Big Dasher, I’m still working on a load, although the same 33.0 grain load shoots in the ones in the heavier gun as well. I’m still looking for more velocity and my ‘max’ node. So far, I’ve gone well above 33.0 grains of RL 15 without pressure signs, but that load produces vertical at 100 yards, so I’m going to tinker with the load until I see pressure or it starts to shoot.
