IBS Match Report by Tom Jacobs and Jim Bauer
“What a wonderful match” — those words were heard often during this year’s IBS 600-yard National Championship match. Tom and Sara Jacobs hosted the 600-yard Nationals September 26-27 at their Vapor Trail Valley Range in Spickard, Missouri. Attendance was strong, with 78 competitors from 14 different states. The Vapor Trail Valley range holds both 600-yard and 1000-yard yard matches throughout the year. Located in northwest Missouri, Vapor Trail Valley sits in the middle of crop ground and cattle country. The terrain is a mixture of tree lines and green pastures.

It seemed every aspect of the match came off flawlessly, thanks to the hard work of the organizers. Even the weather cooperated, with 80 degree days and 60 degree mornings. The wind was mild but twitchy, providing a challenge for the competitors. Overall though, conditions were generally good and some very impressive results were recorded. Despite the twitchy winds, over the course of the weekend, some eighty perfect 50-point targets were shot. That’s darn good shooting overall.

Interesting Factoids from Vapor Trail:
1. Competition is VERY tight now. The difference between 1st place and 20th place in Light Gun Group Aggregate was .478″, less than half an inch. The difference between 1st and 20th place in Heavy Gun Group aggregate was .480″, again less than half an inch.

2. 6mm cartridges, particularly the 6mmBR and Dasher, now dominate the 600-yard Benchrest game.

IBS 600 yard national championship light gun heavy gunAll but one Light Gun was chambered as a 6mm, mostly 6BRs or Dashers. Even in the Heavy Gun division, 6mms ruled — 58 out of 61 Heavy Guns were chambered for 6mm cartridges, mostly Dashers.

3. These rigs are capable of extreme accuracy. The ten best Light Gun groups were all under 1.250″ (FYI, at 600 yards, one-quarter-MOA is 1.570″). And, as you can see at right, the three smallest Light Gun Groups were all under 0.9″. Think about that — a one-inch group used to be considered darn good at 300 yards.

After Friday practice, the match began with the Light Gun relays on Saturday. Both Light and Heavy Guns shoot 8-target Aggregates. At the end of the day Saturday, Tim Gonnerman was the Light Gun Group winner with a 2.236 Agg , edging runner-up Jason Walker by a mere .003″. That’s about as close as it gets. Dan Hullinger won Light Gun Score with a 382 (Danny Wake also had a 382 but placed second on the tie-breaker). Richard Schatz, “Mr. Consistent”, placed 4th for score and 5th for group to take the Light Gun Overall title. Last year’s two gun Champion Ryan Hunt finished in second place.

Equipment Choices of Two Gun Top 20
If you review the equipment list for the Top 20 Two Gun competitors, you’ll find that Nightforce scopes were used by 19 shooters, while BAT actions were used by 15 shooters. Remarkably, 17 out of the top 20 used rifles chambered in 6 Dasher. Hodgdon Varget was the most commonly-used powder followed by Alliant Reloder 15. In the barrel department, Brux enjoyed a slight edge over Krieger, with ten shooters using Brux Barrels vs. seven using Kriegers.

Note the large, extended-width base-plate under the forearm. This spreads the load and provides more stability when used with super-wide SEB MAX front rest.

The Heavy Guns came out on Sunday. Early morning relays saw a dead-flat wind condition that constantly changed as the day progressed. Scores settled a little and groups opened up, creating a little room between competitors. In the end, Bud Larson won the Heavy Gun Score title with a 385 total. This year’s Shooter of the Year leader Andy Ferguson was close behind with a 384. The Heavy Gun group champion is Richard Schatz with a 2.003 Agg, followed by Jim Bauer with a 2.017. The Heavy Gun overall went to Jim Bauer followed by “Andy Who?” Ferguson (see photo below).

The 2015 IBS 600-yard Two Gun Champion is Richard Schatz with 18 rank points. If you look at the new 600-yard traveling trophies, you’ll see Mr. Schatz’s name multiple times — this victory marks the third time Richard has won the 600-yard, Two Gun IBS National Championship in the past decade. Richard Schatz is certainly a great ambassador for our sport and a true gentleman. Second Place in the Two Gun overall went to Jim Bauer, not far behind with 20 rank points. Taking third was Andy Ferguson with 28 rank points.

The top lady shooter was Sally Bauer. A past IBS 1000-yard Shooter of the Year, Sally is a 7-time female National Champion in 600-yard or 1000-yard benchrest. Rory Jacobs was the Junior “Top Gun” this year, winning the Junior division and finishing 10th Overall among ALL shooters (of any age) in the Two-Gun Agg. Rory is a four-time Junior National Champion and three-time Junior shooter of the year. The top Rookie shooter was Carroll Lance.

As with many of the matches that we attend, the range owner’s family and friends make up the help for scoring and target crews, the lunch attendants and general maintenance of the ongoing match. This match is no different. Tom and Sara’s families took care of all the required chores and it all came together like a well-oiled machine. Give credit to Tom Jacobs for working with the sponsors to put together a great prize table — every shooter in attendance got a sponsored prize. Please take the time to let our sponsors know that you appreciate their generous support.

There was an excellent prize table, as this young fellow demonstrates

“Andy Who?” — Ferguson is Front-Runner in 600-Yard Shooter of the Year Race
Here’s the “Andy Who?” story. Andy Ferguson, a good friend and neighbor of the Vapor Trail Valley range owners, is currently leading the 600-yard Shooter of the Year (SOY) point competition. Given his hot shooting and top ranking in the SOY chase, some of Andy’s friends/fellow competitors thought Andy might be getting a “big head” (i.e. oversize ego). To bring him down to earth, as a joke, Andy’s friends printed up the “Andy Who?” T shirts. A good laugh was had by all.

Berger Updates Bullet BC Data and Recommended Twist Rates

Berger BC Ballistics Coefficient Barrel Twist Rate  Updates

Berger has released two important informational updates for its line-up of bullets. First, the Ballistics Coefficients (BCs) have been updated for the vast majority of bullets Berger sells. In addition, G7 model BCs are being provided for most of the bullets. You will want to use the updated BC data, which is based on actual testing of recent production lots of bullets.

Second, Berger is now providing a dual twist-rate recommendation for most bullets. Berger is now lists a “minimum” barrel twist rate as well as an “optimal” twist rate. To get maximum long-range performance from your bullets, use a barrel with the “optimal” rate of twist.

CLICK HERE for the latest Berger Quick Reference Sheets with updated BCs and new Optimal Twist Rates. Eric Stecker, Berger President says: “We have tested every lot of bullets‬ produced in the last several years to bring you these updated numbers for all of our bullets.”

Ballistic Coeffificent (BC) Updates with G7 Data
Berger notes: “We have updated all of our Ballistic Coefficients to be even more accurate.
Prior to 2008, all of Berger Bullets’ BCs were calculated using a computer prediction. Early in 2009, we began measuring BCs with live-fire testing. As a result, Berger’s BCs were updated and G7 BCs were also made available. This represented a dramatic improvement in the accuracy of performance data at that time. Since 2009, the BCs assessed for Berger Bullets have not been updated. As part of our ongoing effort to provide shooters with the best information possible, Berger has been testing every lot of bullets produced for the last several years. The result is updated and highly accurate running averages of BCs for recent production lots.

Here are some of the Updated BC Values for popular Berger Target (Match) Bullets:

Description New G1 BC New G7 BC % Change
22 Cal 80gr VLD Target 0.455 0.233 +2%
22 Cal 90gr VLD Target 0.534 0.274 -3%
6mm 95gr VLD Target 0.467 0.240 -3%
6mm 105gr VLD Target 0.517 0.265 +5%
6mm 105gr Hybrid Target 0.536 0.275 -1%
6mm 115gr VLD Target 0.563 0.289 +3%
6.5mm 130gr VLD Target 0.562 0.288 +2%
6.5mm 140gr Hybrid Target 0.607 0.311 -2%
7mm 180gr VLD Target 0.683 0.350 +4%
7mm 180gr Hybrid Target 0.680 0.349 +1%
30 Cal 155gr Hybrid Target 0.478 0.245 -1%
30 Cal 185gr Hybrid Target 0.576 0.295 +1%
30 Cal 215gr Hybrid Target 0.691 0.354 -1%

G7 Form Factor Addition
Berger also added the G7 form factor to the Ballistics Quick Reference Sheet. The analysis of form factors can be very useful when considering a bullet’s long range performance potential. Going by BC alone can be deceptive since BC includes the weight and caliber of the bullet. Form factor indicates how much drag the bullet has, which is a very important consideration for all bullets of all calibers.

NEW Dual Twist-Rate Recommendations
Recommended twist rates for bullets are commonly listed as a single value, such as 1:12” (one rotation in 12″ of barrel travel). This may be overly simplistic. There is a big gray area of marginal stability in which bullets can fly with good accuracy, but with a reduced (i.e. sub-optimal) Ballistic Coefficient. Recognizing this reality, Berger is now listing two twist rates for each bullet it makes. The first is the minimum twist needed for good accuracy, which Berger has always recommended. The second is the new optimal twist rate, which is the twist that will stabilize the bullet to a level which achieves its full performance (BC) potential. CLICK HERE For more information.
