Custom 6-6.5×47 Varmint rifle with BAT Action and Krieger Barrel

6mm Creedmoor 6-6.5x47 Lapua Varmint Rifle BAT action Krieger Barrel

With all the noise lately about the 6.5 Creedmoor, it’s easy to forget that before we had the Creedmoor, we had another accurate, efficient mid-sized cartridge, the 6.5×47 Lapua. Just as the 6.5 Creedmoor inspired the 6mm Creedmoor, the 6.5×47 Lapua has been successfully necked-down to 6mm (.243) for a 6-6.5×47 variant. This has worked great in a number of roles — benchrest, varminting, and tactical/PRS. This article, from a few seasons back, shows how the 6-6.5×47 Lapua can be successfully packaged as an accurate, potent 6mm varminter.

After selling my 6mm Remington Ackley Improved a couple of years ago and wishing I had not, I thought about a new customer rifle for work on Prairie Dog towns and New York wood chucks at 600+ yards. I have a .223 AR and 22-250 for medium ranges but I missed my 6mm AI for long-range work. The 22-250 is a fine chambering, but it is hard on barrels, and I think the 6mms may have an accuracy edge out past 400 yards. Also, shooters today enjoy a vast collection of really great 6mm bullets. Barrel life and bullet ooptions were two main reasons I decided to build a 6mm rather that another .224-caliber gun. But the question remained — what 6mm chambering to choose? Although I missed my 6mm AI, I did not miss fire-forming the brass, so when I learned about the 6-6.5×47 Lapua, a wildcat case easily formed by necking down the parent 6.5×47 case, I thought this might be the answer.

I started doing serious research on the 6-6.5×47 Lapua. I received a lot of good advice from AccurateShooter.com and other websites on the pros and cons of the new cartridge. Most reports were positive. I also talked to gunsmiths — quite a few recommended the new cartridge as well. Some of the cartridge attributes I liked were the small rifle primer, enough case capacity to efficiently reach 3700 fps with a 70gr bullet and 3400 fps with an 85-grain, without being terribly over-bore.

Most important was the 6-6.5×47’s reputation for inherent accuracy without being finicky like my 6mm AI (my experience). So, having chosen my cartridge, I started asking for gunsmith recommendations. Again the folks on the AccurateShooter Forum were very helpful. After many conversations I settled on Dave Bruno in Dayton, Pennsylvania. He was a good choice. After working with Dave on this project, I could not be happier. He was very helpful considering this was my first complete custom gun.

Putting Together the New Rig with Premium Components
From the get-go, I knew I wanted a BAT action and Krieger barrel. BAT Machine and Krieger Barrels enjoy a great reputation in the shooting industry. BATs are beautifully machined, smooth, and strong. Krieger cut-rifled barrels are known for dependable accuracy and long barrel life. While many 6-6.5×47 shooters choose a 8-twist barrel to shoot the 100-108gr bullets, I would be using smaller, varmint-weight bullets, so I selected a 1:10″-twist Krieger. This would allow me to shoot bullets from 60 grains up to 90 grains. Dave chambered the barrel with an 0.269″ neck and fluted the barrel to save weight. I also had Dave install a Vais muzzle brake. The Vais brake is more expensive than some others, but it is a proven product. Dave fitted the BAT with a 2 oz. Jewell trigger, mounted with a +20 MOA scope rail, then pillar-bedded the BAT into a McMillan Hunter-Class-style fiberglass stock. The scope is a 12-42x56mm Nightforce NSX, mounted in a set of Nightforce rings I hand-lapped for better contact.

I had selected a few powders and bullets recommended by other 6-6.5×47 shooters and started by seating all the bullets .005″ off the lands. The powders I selected were Varget, Vihtavuori N550, and Reloder 15.

I was very pleased with the 88gr Bergers. In initial testing, they grouped well and I was able to drive them to 3400 fps easily. As I wanted a gun for long-range varmint work, I was hoping the 10-twist barrel would provide enough stability for the heavier weight bullets. It did — the 10-twist worked great! I was able to shoot the lighter weight bullets very well and the 88s were superb. With a BC of 0.391, leaving the barrel at 3400 fps, these bullets were still traveling at 2600 fps at 600 yards!

I did wonder how well the 88s would work on varmints given their small meplats (and limited expansion). A call to Berger reassured me the 88s should work fine on small varmints. The test came last summer when I made a trip to NY and got to visit my old Chuck hunting farms with my new rifle and old hunting buddy. The longest shot we had was only 300 yards, but the Berger 88s did great. None of the eight critters we nailed so much as wiggled after they were hit.

I did a lot of testing, recording group sizes for a variety of different bullets and powders. With all the data collected in a spreadsheet, I was able to “crunch the numbers”, and that helped me choose my preferred loads. By looking at the average group size for the individual bullets and powders, the data drew a clear picture of what the rifle shot best. Below is a chart showing comparative group sizes, arranged by both bullet type and powder brand.

IBS Report: 30th Anniversary 2016 Boop Memorial Tournament

IBS Boop Memorial Group Benchrest Shoot Match Pennsylvania

Nate Boop Memorial Match 2016, By Hal Drake, IBS Group Committee Chair
This year marked the 30th anniversary of the Nate Boop Memorial Tournament. 60 shooters from the USA and Canada traveled to Weikert, Pennsylvania, to attend the first IBS benchrest-for-group match of the year. This range is set in some of the most beautiful countryside in the East. All the amenities you could want are within easy walking distance: 30 amp electric hookups, nice covered loading area, restaurant/bar, and even a trout stream! With all this and much more, it’s tough to imagine a more welcoming range than Weikert. It’s not advertised much, but this is a money match (like the Super Shoot), which pays a nice bounty to the top finishers in the Grand Aggs.

Most shooters showed up on Thursday or Friday, and were greeted by heavy rains that made for somewhat uncomfortable practice sessions. As I walked down the line on Friday morning, I couldn’t help notice the number of rifles that wear stocks by Roy Hunter. Roy started making stocks just a few short years ago, after a long career as a custom furniture maker. Top gunsmiths like Sid Goodling, Jim Borden, and Dave Bruno feel that Hunter stocks are at the top of the game. Dave told me that he’s extremely impressed with how “dead” the stock is compared to some of the other top end stock makers. Roy’s design has changed quite a bit since he first started, with the latest creations featuring a thicker area behind the tang, and a very robust forend. I have just recently put a new gun together with the latest Hunter stock, and a Rimrock BR action, and can’t say enough about how this new rig handles. His long range versions have a good following as well.

Potential New Records Set by Allen Arnett and Howie Levy
It stayed cool throughout the weekend, with Saturday being the best day for shooting small Aggs. On Saturday morning, Allen Arnette threw down a potential new Light Varmint 100-yard Aggregate Record of .1478″ (and there were five other LV 100 teen Aggs shot that morning). Amongst Allen’s targets was a potential single-group record of .040″. Boat Tail bullets have been all the rage in the short-range group game for some years, but Allen continues to prove that his flat base bullets are as good as any out there. In the afternoon, Howie Levy compiled a .1386″ Heavy Varmint Agg, a potential new Heavy Varmint 100-Yard Aggregate record (there were six HV teen Aggs). Howie is a Boat Tail guy for the most part, and he left a mark with his new Dave Bruno-chambered Brux barrel, and his own pills.

When the shooting was finished on Saturday, we were treated to a pig roast with enough fixins to make Roy Rogers proud. Dale brought in a caterer who delivered a great meal. He showed up on Friday evening, set up his smoker, and got the pig going in the early morning hours. After getting the flags moved for the next day’s 200, we all gathered in the loading area and enjoyed a pretty special feast.

The crew at Union County Benchrest always puts on a great match, and this year’s 30-year Anniversary made for an even more special event. As usual, the Trutt and Boop Families deserve a big “Thank You” for putting so much time and effort into running seamless matches at one of the premier Benchrest facilities in the country. Hats off to the target crew as well, whom I would put up against any target crew in the country.

Sunday morning brought heavy winds that would only get worse as the day progressed. Dave Bruno had the right stuff in the morning to bring home the win with a .2485″ HV 200-yard Agg. As the afternoon started, damaging winds were ripping up wind flags and trailer awnings. Russ Boop showed us how to get it done though, with a .3046″ Aggregate in the trying conditions. When all the dust cleared, the Grand Aggs were split by Howie Levy and Dave Bruno, with Howie narrowly sneaking by Dave for the Two-Gun win. Kevin Donalds Senior put on a strong showing to take third.
