Last month, shooting at the Piedmont Gun Club, Chad Jenkins put together a stunning 1.495″ Aggregate at 600 yards. Once certified, that will be a new IBS 4-target Light Gun record. Chad’s smallest group was a 1.033″. Chad’s 1.495″ Agg breaks the existing 1.6068″ record set by Sam Hall in 2011. Chad was shooting a no-turn-neck 6mmBR featuring a BAT action, Krieger barrel, and Shehane ST-1000 fiberglass stock. We had the chance to talk with Chad and learn more about his record-setting rifle, and the methods he uses to achieve superior accuracy. Chad was kind enough to tell us about his equipment and what he does to build very, very accurate ammo. For starters, Chad wanted to “say thanks to Lewis Winkler, James Coffey, Mike Davis, and Larry Isenhour” all of whom provided invaluable help and support over the years.
The Record-Setting Rig
Chad credits much of his success to an “fantastic Krieger barrel that shot great right out of the gate”. It’s a 1:8″ twist, HV contour, finished at 28″ — nothing unusual there. Mike Davis did the chambering, barrel-fitting, and barrel crowning. One reason the gun shoots so well is that Chad’s friend James Coffey did the stock work and bedding, and also added weight to the Shehane ST-1000. Chad says “James really knows what he’s doing”. For optics, Chad uses a Leupold 45X competition scope, with fine cross-hair (FCH). Chad says he can “aim at the ‘X’ at 600 yards more precisely with the cross-hairs than with a target dot.”
$200 Front Rest Good Enough to Set Record
You may be surprised that Chad set his record with an inexpensive Caldwell Fire Control Joystick rest, that sells for about $203.00 on Amazon.com. The Caldwell isn’t fancy, but it did the job. Chad says: “I have a family and a young boy. I don’t have the money to pour into equipment like some other people. I will continue to use my Caldwell, but I have recently modified the base. The record though was set with an unmodified unit, just as it appears in the photo.”
Chad Shoots a “Classic” 6BR Load, But He Jumps his Berger VLDs
Chad gets great accuracy with a pretty “standard” 6mmBR match load: 30.5 grains Varget, CCI 450 primers, Berger 105gr VLDs, in Lapua “Blue Box” brass. (Editor’s Note: That load can be too hot in some guns in summer conditions). Chad loads his ammo with a Redding bushing full-length sizing die with an 0.266″ bushing. Chad says: “That’s a good size for the ‘Blue Box’ Lapua brass (I tried a 0.268″ and I could pull the bullets out with my fingers). I seat my bullets about 0.020″ OFF the lands with a Redding Comp seater die.” The brass that shot the record Agg had about 10-11 firings on it, and Chad has NOT annealed the cases yet. While Chad is a very exacting reloader, he believes in the KISS principle — he doesn’t ream flash holes or uniform primer pockets. While he weighs every load with an RCBS Chargemaster, he normally does not double-check charges with a second balance. Chad tells us: “I just get the Chargemaster to where where it is going consistently and run with it.”
Knowing that gun-handling and barrel maintenance are key elements of accuracy, we asked Chad about his shooting style, rest set-up, and his cleaning regimen:
Shooting style: “I try not to touch the gun, except with my thumb on the back of the triggerguard, and my index finger on the trigger. I use just a slight amount of pressure as the finger pulls the trigger. I don’t have any pressure on my shoulder. The buttplate is just barely touching my shirt.”
Rest position: “I usually let the gun run out to the stop. But there’s not much overhang. It hangs over an inch and a half. That’s where I always shot it. In the rear the ears are pretty much centered on the underside of the buttstock.”
Cleaning: “I use Montana X-Treme with patches and bronze brushes, and I clean every 35-45 rounds. I don’t brush a lot — I kind of go on feel, anywhere from 4-10 strokes. The gun shoots so incredibly well, I want to baby it, so I try not to over-clean.”

Common Sense Tips for New Shooters
Chad offered some advice for shooters starting out in the 600-Yard Benchrest game:
Reloading — I don’t claim to be an expert. But I will say that consistency is all-important. I learned this first from my friend Lewis Winkler (who passed away), and then James Coffey. Lewis always told me that the main thing is that you must be consistent in everything — when you’re sizing, when you’re weighing, when you’re seating bullets. You can’t be deviating and expect your loads to shoot.
Mental Game — I don’t go to a match to beat anybody, or to compete against anyone in particular. I shoot the best I can shoot and let the chips fall where they may. Even in practice, I basically compete against myself and I try to do the same thing in a match.
Focus (when to have it and when to relax) — I do try to stay focused when I’m shooting. But I also try to get away from the pressure between relays. A lot of the guys spend 15-20 minutes looking at everybody’s targets. I just look at my own targets and go back and sit down and relax. I don’t try to overthink things. When I was a teenager I was a successful competitive golfer. And in those days, I didn’t think about it … I just stepped up to the ball and hit it. I think, with some competitive activities, “thinking too much” can probably mess you up more than it helps.

You don’t hear much about PacNor barrels in long-range competition, but FORUM member Wes J (aka P1ZombieKiller), proved that they can shoot “lights-out” in a rig assembled by a talented gunsmith. Wes tells us: “Since I restocked my 6BR more than a year ago, I have not had a chance to shoot it much since I have been playing the 100-200 game. Well, last week I decided to take it out and do some playing at 500 yards. I have to give some serious props to my buddy (and fellow FORUM member) ‘PREACHER’ who did the chambering and barrel work for me. He can certainly make a gun shoot good. The barrel is a PacNor 1:8″ twist. My load was 105gr Berger VLDs pushed by 29.6 grains of Varget.” The five-round, 500-yard group shot by Wes J with his 6BR, measured just 1.240″, as measured by OnTarget software. Now that’s one accurate rig!
This Editor knows something about the potential of a PacNor barrel. I have a 3-groove stainless PacNor SuperMatch on my trusty Savage-actioned 6BR. This barrel shoots quarter-MOA or better in calm conditions, and it cleans up super-easy. The interior finish is so good, I’ve never had to brush the bore or use abrasives, and after 750 rounds it shoots as well as ever. I attribute the easy cleaning to the fact the lands in a PacNor 3-groove are wide and flat, so they are gentle on bullet jackets. I think accuracy is helped by the fact that PacNors run on the tight side (0.236 land dimension) with a good amount of choke. That works well with the 105gr Lapua Scenars and 103gr Spencers I like to shoot. You can read more about my rifle, nick-named the “Poor Man’s Hammer”, in this Feature Article from our archives. In its last outing the Poor Mans’ Hammer put 3 shots in under 0.200″ (measured center to center) at TWO Hundred yards. If you get a good one, PacNor three-grooves can definitely shoot.
 Target Measurement with OnTarget Software
We used OnTarget software to measure the 5-shot group in the target above. This easy to use software is very repeatable, once you get a feel for plotting the shots. The basic version 1.10 of OnTarget is FREE, while there’s a modest $11.99 registration fee for version 2.10. In addition to group size (in inches), OnTarget plots distance to aiming point, and the software automatically calculates the group’s vertical height, horizontal dispersion, average to center (ATC), and group size in MOA.
You can run a measurement on a scanned target or a photo of a target. You’ll need some known reference to set the scale correctly. The target above had a one-inch grid so it was easy to set the scale. Once you’ve set the scale and selected bullet diameter and target distance, you simply position the small circles over each bullet hole and the OnTarget software calculates everything automatically, displaying the data in a data box superimposed over the target image. To learn more about OnTarget Software, read AccurateShooter.com’s OnTarget Product Review. This article covers all the basics as well as some advanced “power user” tips.

Forum member Darrel Evans from the UK pulled off a remarkable feat recently. He set multiple 600-yard UK benchrest records shooting a true, military-type tactical rifle, an Accuracy International AW chambered in 6.5×47 Lapua. The gun had a custom 24″ fluted Border barrel, and bag-riding accessories, but other than that, Darrel’s gun was very much “as-issued” by the factory. Darrel pulled off this fine display of precision shooting at the December 27th 600-yard benchrest comp at England’s Diggle Ranges. (The Diggle, as you may know, is notorious for difficult conditions.)
Report by Darrel Evans
Just thought that you all might like to know how I have been getting on with my Accuracy International AW chambered in 6.5×47 Lapua. To make a long story short, I broke three UK records: smallest group of the day — 1.8″ at 600; smallest Agg for the day — 2.8″; and smallest Agg for the Light Gun class — 2.8″. All these records can be viewed on the UKBRA and TargetShooter websites.
To say that I was ‘over the moon’ would be an understatement. I was happy that all of my hard work had paid off. I was delighted to set records on the rifle’s first outing since [adding bag riders]. The 600-yard benchrest comps over here are run as a winter competition and the winds at the Diggle are not very forgiving. I knew that the group was small as the markers were over lapping each other when the target board came back up. But when they told me that it was 1.823″ I knew that I had got a record, as the last record of 2.225″ was set by myself in 2009 on the first Comp with the 6.5×47 barrel on, this was then broken with a 2.18″ on a calm day later that year. Later I received an email from Vince Bottomley telling me that I also had the best factory Agg record and the Agg record for Light Gun class.
About Darrel’s 6.5×47 Accuracy International
My Accuracy International AW (AI-AW), a military rifle system, started life as a .308 Winchester when I first bought it. But after a lot of reading I decided to buy a 6.5×47 Lapua barrel for it. As you know the AI-AW rifle system is a very good switch-barrel design, so after a phone call to Graeham Clark at Sporting Services I bought a Border Barrels 24″ fluted barrel in 6.5×47 Lapua. My .308 barrel is now in my gun safe. After seeing how the 6.5×47 barrel shoots, I doubt the .308 tube will ever go on again.
The rifle falls in the Factory Class for our 600-yard BR comps. This also qualifies in the Light Gun class. Most folks say that a factory rifle will never beat the custom lads in the Light Gun class…. Well, sometimes it’s nice to see this happen. To help the rifle’s bench manners, I made a plate for the front so that it would sit on my compact front rest with a Farley joystick top. I also made a bar to fit on the bottom of the buttstock for the rear sandbag.
Load Development and Accuracy Testing
 After a lot of testing with different powder and bullet combos, I settled on 38.2 grains of Hodgdon Varget, with 130gr JLK bullets and CCI 450m primers. Velocity is 2914 fps. Seems that this is where it likes to be. In the photo below, you can see the results of a few different powders, but all with the fantastic JLK 130gr bullets. The 38.3 Varget load had all four rounds in nearly one hole and I pulled the fifth, so this was pretty much the load that I went with for my 600-yard Comp. The JLKs are really good, consistent bullets, and I think that the next barrel that I buy will be set up for these bullets and no other — they are that good. I seat the bullets at 2.157″ OAL, just kissing the lands. I could not go any further out as the bearing surface is short.
Wrapping up his success story, Darrel added: “I hope that this is of some help to people who have a 6.5×47 or are thinking of building one. All the best for 2012.”

 Alliant is introducing a new extruded powder, AR-Comp. AR-Comp is an advanced re-formulation of Reloder 15, a double-base Bofors powder. There are changes to internal and external chemistry to provide much better pressure/velocity stability across a wide range of temperatures. The main difference between AR-Comp and Reloder 15, is the AR-Comp has a slightly faster burn rate, and AR-Comp is much LESS Sensitive to temperature changes. AR-Comp is a small-kernel, double-base extruded powder like Reloder 15, so it will continue to meter just like Reloder 15. The load density should be the same as Reloder 15.
AR-Comp should be at Grafs.com in a Couple Weeks
Here’s the good news — Alliant will start shipping AR-Comp to Grafs.com later this week. Dick Quesenberry, Alliant Powder Product Manager, told us: “I just received the AR-Comp packaging labels and we hope to send off the first shipments to Grafs this week.” With transit time, expect the powder to be available from Grafs.com by the second week of June. You can go ahead and place advance orders for 1-lb and 8-lb containers of AR-Comp on the Grafs.com website.
AR-Comp Offers Uniform Velocities over a Wide Temp Range
Tests were done with .223 Rem and .308 Win ammo, loaded with AR-Comp and maintained at temps from -20° F to +160° F in a controlled test center. The ammo itself was heated or cooled to targeted temps before testing. Across that entire range of temperature, -20° F to +160° F, the ammo loaded with AR-Comp showed a variation of only 20 fps in muzzle velocity. The primary bullet type tested was a 77gr .224 bullet and the secondary was a 175gr .308 bullet.
Burn Rate Like Varget
Though this is a reformulation of Reloder 15, the burn rate of AR-Comp is slightly faster than Reloder 15. Alliant told us: “Reloder 15 is slightly slower, in burn rate, than Varget. The new AR-Comp, with the enhancements, ended up slightly faster than Reloder 15, so it is now very close to Varget in burn rate”. This is the result of the “tuning” of the powder to be much less temp-sensitive.
AR-Comp First in Series of New Alliant Temp-Stable Powders
AR-Comp will be the first in a series of “new generation” temp-stable powders from Alliant. Quesenberry noted: “Our goal was to provide a powder that offers stable pressures in all temperatures. Shooters want to be able to stay with the same load in winter and in summer, in cold or in hot conditions.” Quesenberry added: “We’ve been working on this quite a while. AR-Comp is the first example and we hope to extend this to other rifle powders. It’s a tough job. You have to balance the performance carefully. We worked very hard to do just that and we think shooters will be impressed with the results.”
Reloder 15 Will Stay in Production
Fans of Alliant’s Reloder 15 don’t need to worry. Alliant will keep Reloder 15 in production. “We don’t drop powder lines”, said Quesenberry.

Loaded Ammo: We asked if any manufacturer will be using AR-Comp in loaded ammo. Dick told us that he is “not allowed to release that information at this time”. Draw your own conclusions, but remember that Alliant is owned by ATK, which makes Federal rifle ammo.
Available in Summer 2011: Allliant hopes to ship AR-Comp in “June or July” of 2011, provided the DOT Classification process moves at a normal schedule. The powder is ready to go, Alliant is just waiting on the DOT to provide shipping authorization.
Reloder 15 Will Stay in Production: Fans of Alliant’s Reloder 15 don’t need to worry. Alliant will keep Reloder 15 in production. “We don’t drop powder lines”, said Quesenberry.
AR-Comp First in Series of New Alliant Temp-Stable Powders

Quesenberry added: “We’ve been working on this quite a while. AR-Comp is the first example and we hope to extend this to other rifle powders. It’s a tough job. You have to balance the performance carefully. If you tweak it one way, say to improve the low temp performance, you lose something at the upper end. If you tweak it for the top end, you loose something at the bottom. You have to hit that balance. We worked very hard to do just that and we think shooters will be impressed with the results.”

Here’s important news for handloaders. Alliant Powder has introduced a new medium-burn-rate powder: AR-Comp™. This new powder was developed specifically for AR-style rifles. Alliant says that AR-Comp powder is “ideally suited for heavy .223 and .308 match bullets”. We presume, from that description, that the powder will have a burn rate similar to Varget. The AR-Comp powder, produced in Sweden by Bofors Nobel, is an enhanced temp-insensitive reformulation of Reloder 15. The burn rate is slightly faster than Reloder 15, according to Alliant.
Alliant Claims AR-Comp is NOT Temp-Sensitive
We have limited information about AR-Comp, and we have not yet been supplied with a test sample. We have confirmed is a double-base extruded powder, and is an upgraded version of the Reloder 15 formulation. Alliant claims the powder meters very well and delivers “consistent pressures and velocities across temperature extremes”. This new powder is supposed to be very uniform from lot to lot. That would be great — if it is true — but only time will tell.
We will try to get a sample of AR-Comp soon and test it in both .223 Rem and .308 Win rifles. We suspect, if AR-Comp suits both the .223 Rem and .308 Win, it should work well in the 6mmBR and 6.5×47 Lapua cartridges as well. Stay tuned — we hope to have more info next week. AR-Comp should be hitting the market in June or July, 2011, provided DOT Classification goes smoothly. It will be offered in both one-pound (#150664) and 8-lb (#150665) containers.

We are often asked “Can I get more velocity by switching primer types?” The answer is “maybe”. The important thing to know is that changing primer types can alter your load’s performance in many ways — velocity average, velocity variance (ES/SD), accuracy, and pressure. Because there are so many variables involved you can’t really predict whether one primer type is going to be better or worse than another. This will depend on your cartridge, your powder, your barrel, and even the mechanics of your firing pin system.
Interestingly, however, a shooter on another forum recently did a test with his .308 Win semi-auto. Using Hodgdon Varget powder and Sierra 155gr Palma MatchKing (item 2156) bullets, he found that Wolf Large Rifle primers gave slightly higher velocities than did CCI-BR2s. Interestingly, the amount of extra speed (provided by the Wolfs) increased as charge weight went up, though the middle value had the largest speed variance. The shooter observed: “The Wolf primers seemed to be obviously hotter and they had about the same or possibly better ES average.” See table:
| Varget .308 load |
45.5 grains |
46.0 grains |
46.5 grains |
| CCI BR2 Primers |
2751 fps |
2761 fps |
2783 fps |
| Wolf LR Primers |
2757 fps |
2780 fps |
2798 fps |
| Speed Delta |
6 fps |
19 fps |
15 fps |
You can’t extrapolate too much from the table above. This describes just one gun, one powder, and one bullet. Your Mileage May Vary (YMMV) as they say. However, this illustration does show that by substituting one component you may see significant changes. Provided it can be repeated in multiple chrono runs, an increase of 19 fps (with the 46.0 grain powder load) is meaningful. An extra 20 fps or so may yield a more optimal accuracy node or “sweet spot” that produces better groups. (Though faster is certainly NOT always better for accuracy — you have to test to find out.)
WARNING: When switching primers, you should exercise caution. More speed may be attractive, but you have to consider that the “speedier” primer choice may also produce more pressure. Therefore, you must carefully monitor pressure signs whenever changing ANY component in a load.
Plenty of CCI-BR2 and Wolf Large Rifle Primers in Stock
If you’re looking for either the CCI BR-2 or Wolf Large Rifle Primers, Wideners.com currently has both in stock. The CCI BR2 primers (item CCIBR2) cost $42.50 per 1000. The Wolf LR Primers (item QQQLR KVB-7) cost $29.50 per 1000 OR $142.00 per 5000.

We all know that certain popular powders are very hard to find right now, and the situation for rifle primers is even worse. With increased demand from various sources, available supplies of Varget and other powders have dried up, creating incentives for some folks to resell powder and primers at windfall prices.
Recently, one 8-lb jug of Hodgdon Varget sold for $680.00 on Gunbroker.com. You read that right — SIX hundred eighty dollars. Add $35 for shipping and hazmat fees and you’re talking $715.00 for a jug of Varget, or $89.38 per pound, nearly four times the going price before the “panic buying” started.
Eighty-nine bucks for a pound of powder is crazy. We caution our readers not to get caught up in such nonsense. First, if you can’t find a particular powder, such as Varget, there are good alternatives available at reasonable prices. Norma 203B is an outstanding powder, very similar to Reloder 15, that works well in place of Varget. Grafs.com has plenty of 1-lb cans of Norma 203B in stock, Item Number: NP203B1, priced at $24.99 per pound. (That price includes shipping but not Haz Mat fees.)
We also expect the supply situation to stabilize in the next few months. Hodgdon recently received 22,000 pounds of Varget powder. Those supplies (along with other Hodgdon powders) should make their way to vendors soon, and that should relieve some of the shortages which encourage price-gouging.
As for the primer situation, things should remain tight for a while. All the primer makers are running at full capacity, but it could be some months before we see normal primer inventories at most large retailers.
