There’s a lot of buzz about ballistics programs for smartphones. Those are handy, to be sure, but most people still need a solid, full-featured program to run on their home computers. Berger Bullets offers a sophisticated ballistics programs for MS Windows computers that works really well, and lets you print out results. Up-to-Date G7 BCs for Berger projectiles are built-in to the program, and the price is right — FREE.
CLICK HERE to Download Berger Ballistics Program
The program is basic enough to be easy to use, but flexible enough to allow you to calculate custom ballistics for your rifle and load. The program accounts for all the basic external ballistic parameters including bullet BC and muzzle velocity, atmospherics, uphill/downhill shooting, etc. The output tabulates velocity, energy and time of flight as a function of range. Bullet path and wind deflection are displayed in your choice of inches, centimeters, MOA or MILS.
Instructions for Program
On the Berger Bullets Blog (1/26/2010), You’ll find a description of program features and a complete set of instructions. Here are instructions for the bullet variables: “The bullet inputs are straightforward. The BC can be entered in reference to either the G1 or G7 standard. You can find the G1 or G7 BC for your bullet either printed on the bullet box label, or on our products page. For accurate results, you should measure the muzzle velocity with a good chronograph. If you don’t have access to a chronograph, you can estimate the muzzle velocity based on your load data.”
Tips for Best Results
Bryan Litz includes tips on getting the most from the Berger Ballistics program. Some of Bryan’s suggestions will also help you when working with other ballistics software:
G1 vs. G7 BC: The accuracy of the ballistic solution is only as accurate as the inputs you give it. The advertised BCs for Berger bullets are established by actual field firing tests over long range and are very accurate. Using the properly referenced BC (G7 vs. G1) for the bullet you’re modeling is important. For any bullet with a boat tail, we recommend using the G7 BC.
Muzzle Velocity: Knowing your true muzzle velocity is important when calculating external ballistics. It’s best to measure your muzzle velocity directly with a chronograph.
Altitude and Atmosphere: If you want a truly accurate long-range trajectory prediction, you can’t ignore atmospheric effects. This is especially true the farther you get from standard conditions (sea level altitude, 59 degrees Fahrenheit, 0% humidity).
Scope Verification: It’s important to verify the most important link between the calculated ballistics and your point of impact: your scope. If the ballistics program calculates 30.0 MOA of drop for a particular shot, and you dial your scope to 30.0 MOA, are you sure it’s giving you exactly 30.0 MOA? In reality, many scopes have enough error in them to cause misses at long range. It’s important to verify the value of your scope clicks by firing groups at short range.
If you have further questions not answered on Berger’s Blog Page, email Bryan.Litz [at] bergerbullets.com. NOTE: If your computer won’t run the program, please download and install this Java update: http://www.java.com/en/download/index.jsp. This is a Windows PC program. You may have problems trying to run it on a MAC in emulation.

The Berger SW Nationals at the Ben Avery Range outside Phoenix concluded this weekend. Congratulations to: Bryan Litz (Overall Champion — sling), Trudie Fay (Palma Rifle Winner, 2nd Overall), Danny Biggs (F-Open Winner), and John Hayhurst (F-TR Winner). Among sling shooters, Bryan shot a 1441-77X, Trudy scored 1432-63X, and Gary Eliseo and Leo Ahearn tied with 1430-74X, with Gary getting the 3rd place spot on a tie-breaker.

Bryan Litz and Gary Eliseo Loads
For the Palma matches, Bryan Litz was shooting a .308 Win with 185gr, .30-cal LRBT Berger bullets, seated .015″ off the lands in Lapua brass. The load, pushed by Hodgdon Varget and CCI BR2 primers, ran slightly over 2800 fps. For his “Any Rifle” stages, Bryan shot a straight .284 Winchester at “about 2850 fps”, using 180gr Berger Hybrid match target 7mm bullets seated about .015″ off the lands. Bryan’s .284 Win load used Hodgdon H4831sc powder, CCI BR2 primers, and Lapua 6.5-284 brass, necked-up to 7mm. While Bryan favored a 7mm “Any Rifle” chambering, Gary Eliseo did well with a 6mm solution. Gary told us that, except for the Palma match, he was shooting his regular Across-the-Course load: 6mm BRX, 107gr Sierra MK jumped .025″, running about 2940 fps. This is a mild load for the 6BRX and it proves the little cartridge can be competitive at 1K even in tough conditions.
Biggs Breaks F-Class Record
In winning the F-Open Division, Danny Biggs broke Charles Ballard’s 1000-Yard F-Open National record twice with two 200-15X scores. This was an amazing performance by Danny, who finished with 1439-76X Agg, five points ahead of runner-up David Mann. Forum member TonyR, who shot in the match, reports: “The big story is really Danny’s second 200-15X. He shot that through several big switches and most of us can’t figure out how he did it. I shot the same relay he got the first one on and I wasn’t surprised that someone broke the record on that one, but I was scoring another shooter on the relay when he set the second one and I was just amazed that he did what he did under those conditions.”
Sierra Spindle Shooters Top F-Open Team Events
In the team events, the Sierra Spindle Shooters’ Team did very well, winning both the Palma Match and the 1000-yard Team Match, and scoring 2558-102X overall. Team Berger (2550-97X) finished second in the Team Aggs, with Team Berger member Larry Bartholome posting a 645-24X, the best individual performance in the Team comps. In the photo below (left to right), are Spindle Shooters team members Jeff Cochran, Bret Solomon, Shawn Ahrens and Jeff Traylor. Jeff reports: “The medals are for winning the F-Open Team Agg. In the last few years we’ve won the F-Class Nationals with Nancy Tompkins or Emil Praslick coaching. At this match both of them had other obligations so Bret and Shawn co-coached. They did a great job working together beating out several teams with world class coaches. We hold both the 600 and 1K F-Open team records with and had a good shot at the Palma record in this match but came up a bit short. I think if Nancy wasn’t tied up with the U.S. Palma team we might have beat the record. She’ll be with us again soon at the Nationals this fall in Lodi, Wisconsin.”

Berger Bullets has released a brand new bullet designed to work in 6mm rifles with a 1:10″ or faster twist. This new bullet borrows its basic design from the very accurate 95gr VLD, but it is shorter so it can fully stabilize in a 10-twist barrel.
This thin-jacket hunting bullet has been confirmed in testing to work in a 1:10” twist or faster barrel, and was specifically designed for those who want to hunt with factory rifles. Berger Ballistician Bryan Litz field-tested the new 87gr bullet. Here is his report:
For the new 87gr VLD, the G1 BC is .412, and the G7 BC is .211. Prior to this bullet, our lightest Hunting VLD was the 95 grainer, which requires a 1:9″ twist. This left many shooters with no option from Berger for a 6mm hunting bullet because the fastest common twist for many 6mm factory barrels is 1:10″. The 87 grain VLD was designed specifically to fill the gap, and it squeezes the most performance possible out of the common 1:10″ twist barrel. As with all Berger Hunting VLDs, this is the standard J4 (thin) jacket. There is not a Target (thick-jacket) version planned for this design.
L to R – Berger 6mm 87 gr, 95 gr, 105 gr, and 115 gr Match Grade Hunting VLD.
87gr VLDs are In Stock and Ready to Ship
Eric Stecker tells us: “We are excited to announce that our 6mm 87gr Hunting VLD bullets are now available. They are on the shelves now and ready to ship. We have made several shipments to dealers and have more bullets in stock at our shop now. We also have enough jackets ready to make more if we run out quickly. Currently the 87gr VLD is only available in 100-ct boxes.”

October 6th, 2010
Many shooters using the 6mmBR case or a 6BR Improved (6 BRX, Dasher), automatically assume they should be shooting the heavier 105-108gr bullet designs because these offer the “best” ballistic coefficient attainable with a bullet that can work in an 8-twist barrel.
However, if you are shooting a 6BR at medium ranges, say 250 to 400 yards, you should seriously consider trying the 90-95 grain class of bullets, which includes the Berger 90gr Match Target BT, the Lapua 90gr Scenar, the Berger 95gr Match Target VLD, and the Sierra 95gr MatchKing.
First, you may find that, in your barrel, the 90-95 grainers are easier to tune in terms of seating depth, and they may offer somewhat better raw accuracy — yielding smaller groups than the heavier bullets. But remember — each gun/barrel is different.
Second, another advantage of the 90-95s is that you can fill the case fuller with the Varget/RL-15 class of powders (with appropriate throats). You can use more powder and therefore get closer to an optimal 100% case fill. With a 95gr VLD seated long we were able to get virtually 100% fill with a slow lot of Varget. Don’t try that with your 105s!
Lighter Bullets Offer More Speed in a 6BR
You’ll find that, in a standard 6mmBR rifle, you can drive the 90-95 grainers considerably faster than the 105-108 grain bullets at equivalent pressures. In an Eliseo R5 Tubegun, with Broughton 27.5″ 5C barrel, we were able to push the 95gr VLDs a full 160 fps faster than the 108s. This means that the true ballistics of the 90-95s rival that of the heavy bullets — at medium ranges.
We were able to drive the 90-grainers and the 95gr VLDs comfortably and very accurately at 3050 fps, whereas we maxed out at about 2890 fps with the 105gr and 108gr Bergers. At 300 yards, the 95gr bullet’s speed advantage compensates, in large part, for any BC shortfall compared to heavier bullets. In fact, in our rifle, the 95gr VLD actually shows less wind drift at 300 yards than either the Berger 105 Match Target BT or the Berger 108 Match Target BT. See chart.
Here’s data from JBM Ballistics, using G7 Coefficients (500′ alt, 70° temp):
LESSON: Don’t always assume that the heavier bullet has superior ballistics. You have to test, find the accuracy nodes for each bullet in your gun, and run the ballistics for the velocities you can actually achieve with good accuracy. As above, you may be surprised. In our Eliseo Tubegun, the 90-grainers shot tighter than 105s and we gave up little, if anything, in wind drift at 300 yards.
Great Accuracy from 90s and 95s in 6mmBR Tubeguns
In our Broughton-barreled Tubegun, the most accurate bullet so far has been the 90gr Lapua Scenar. In a Savage 6BR with 3-groove PacNor Barrel the Berger 95gr VLD has been ultra-accurate. But we really want to try the 95gr Sierra MK as well. Forum member Randy (aka “InfantryTrophy”) has been shooting the 95gr SMK with great success, and impressive accuracy. Here is his report: “The 95 SMK shoots great. I have not had the opportunity to shoot the 95s at 200 or 300 yards, but I can’t think of anything better to use. This is my first 5-round group fired after about 15 break-in rounds. The load is 29.5 grains of Reloder 15 with SMK 95. The gun is an Eliseo R5 with Pierce action and Broughton 27″ barrel. Shown below is a 5-shot, 100-yard group shot at 100 yards on MR31 target with iron sights, from rest.” Randy measured his group at 0.214″. It looks a bit bigger than that to us, but it is still impressive:

Berger Bullets has just released a video report from Eric Stecker, Berger’s “master bulletsmith”. In this video update, Eric explains why Berger’s popular 6mm, 25 cal, and 7mm bullets are in short supply. Eric reports that production delays were caused by mechanical problems with the jacket-making presses. The good news is that the jacket presses have now been fixed (this required a complete rebuild of the 7mm press), so production should be back on schedule very soon. You’ll find more current news and match reports on Berger’s new Facebook Page.
Berger also announced that, in order to better respond to customer inquiries, Berger has added a new representative to the customer service staff, Teresa Collins. You can contact Teresa by phone at 714-447-5456 or send email to: teresa.collins [at] bergerbullets.com.

IBS 600-yard National Champion and recent 600-yard Shooter of the Year Sam Hall has been hard to beat when he’s got his 6BR or his Dasher dialed in. Sam recently told us that he’s been experimenting with the 6.5×47 Lapua cartridge, thinking that a larger, higher-BC bullet might perform better in the wind.
Sam’s competitors are probably hoping we’ll report that Sam is struggling with the new cartridge, and can’t get his new 6.5×47 to shoot. Well, guys… no such luck. Sam recently took his 6.5×47 Heavy Gun out in some fairly windy conditions, but still returned a spectacular four-shot group at 600 yards. Sam measured the group at 0.357 inches. We measured it at 0.371″ with OnTarget software, but that was going off a photograph, which can be less precise. Either way, 4 shots in well under 0.4 inches at 600 yards is spectacular.
As Sam told us, however, “I just wish I’d shot that in competition… with a fifth shot of course.” Even though Sam’s group was shot in practice, it’s still an amazingly small group — one that suggests that the 6.5×47 Lapua may have great potential as a Benchrest cartridge. The group size, in MOA, is 0.059!
Sam’s load was 37.0 grains of Reloder 15 with 130gr Berger VLDs and CCI BR4 primers. The gun is a Bat-actioned, 47-lb “true heavy” built by Leonard Baity using a McMillan 50BMG stock. The barrel is a 29.5″ Brux, 1.25″ straight contour, with a 1:8.5″ twist. Sam reports:
The gun has a BAT MB 1.55″ round action. The reamer was a Kiff (PTG) .290 neck with .160 freebore. The loaded round is .288 at the neck. I made a mistake labeling the target. The primers were CCI BR4s, not 450s. The 130gr Bergers VLDs are lot 0225 (the early ones). They are in the rifling as far as I can get them (jam). I use a .287 Redding bushing in my Redding “type S” FL dies. I seat with a Wilson seater. The stock is a McMillian Light 50 BMG stock full of lead from McMillian. With the 40x Leupold it weighs 47 pounds. The fore-end is 3.5 inches wide. Leonard Baity did the complete rifle. I had him to put a rail (3 inches wide) on the back so I could use my adjustable rest Leonard made me a few years ago for my Shehane Maxi-Tracker stock. Even though this rifle is only 14 pounds lighter than the 61-pound aluminum stock Maxi-Tracker 6mm Dasher I shot last year, it feels like it is 25 pounds lighter. It is much, and I mean MUCH more manageable carrying this rifle around than the Maxi-Tracker. I can actually use my Farley, joy-stick rest with the rifle. I just replace the 3 inch bag with a 3.5 inch wide bag. I can make adjustments much faster with the Farley than I can twisting knobs.
The reason I built the 6.5×47 Lapua is to try to beat the wind we have here in NC in the spring. Plus, the fact I love to shoot and experiment. The 6.5 bullets are not affected as much by the wind as the 6mms. I started shooting 600-yard competiton with a 6.5-284. I could predict where the bullet was going to hit much better with it than the 6mms I shoot now. In windy conditions, the 6mms seem to “dance around” when sighting in. The heavy 6.5 seems to say on track and Point of Impact is more predictable. In 600-yard competition, score is half the game. I figured if I could get a 6.5 shooting somewhere close to a 6BR or 6BR Improved, I would be ahead of the game in the wind. So far this rifle is agging at 600 yards pretty close to my Dasher and BRX, but not better. After I found this load that shot the 0.357 inch 4-shot group, I went out and shot four more, 4-shot groups in some wind of 10-20 mph and the rifle agged 2.08 inches.
I am still haunted by a “flier” in each group. I am still trying to work that out. The 0.357 group I will say was a fluke because it is the only group I have shot that did not have a flier. The rifle sure won’t group like that every time, but that one time sure was pretty! You may ask why I shoot 4-shot groups during load development and practice. Three is not enough, but four will tell you what the rifle will do, plus I can shoot more groups before the barrel gets too warm.
Our first match is next month at Piedmont. I am going to give this rifle a try. Time will tell if I will stick with this round for serious 600-yard competition or back to the 6mms. — Samuel Hall

While in Southern California recently I couldn’t pass up the invitation to spend some time with my friend Michelle Gallagher, the Marketing Coordinator for Berger Bullets. After my obligatory visit to Disneyland, Michelle offered me a tour of the Berger Bullets factory. That is something even a Sierra guy knows not to pass up!
The machines now run 24 hours a day to keep up with market demands. To increase production, Berger recently started a third shift, allowing the machines to run at maximum capacity. We walked into the factory to the sound of a machine pressing out bullet jackets: “ca-chung, ca-chung, ca-chung.” It is so loud that hearing protection is worn by the operator. Copper is fed into the jacket-making machine from a large coil. Then a series of sequentially deeper, narrower punches create one complete bullet jacket for every revolution of the machine’s huge crankshaft. The operator monitors the whole cycle, selecting jackets at random to test for dimensional accuracy.
After the jackets are formed, lead is placed into the jackets. As with the copper jacket material, the lead is fed into a large machine from a coil. Lead cores are then cut to length and given an approximate shape, a process called swaging. This particular core-forming machine has been in use since before WWII! Michelle said “these machines still work great so there is no reason to switch to anything else”.
Next the copper jackets and lead cores are combined and shaped using a successive series of precision dies. The bullets are swaged (squished really) from the bottom up once the lead is inserted into the jacket via a tube feeder. This ensures there are no air bubbles between the lead core and copper jacket. I watched as one such machine was set up and calibrated. It was started then tested and adjusted a number of times before it was left to run automatically. Even then, handfuls of bullets are frequently tested for weight, concentricity, and dimensional accuracy. I was told that if any lot is found to be bad — for whatever reason — the entire lot is just thrown away! Sorry, but this means no boxes of seconds or “blems” at bargain prices from the Berger factory.
Some details of Berger’s operation surprised me. A number of tasks that I assumed would be automated are still done by hand, ensuring both accuracy and consistency. Bullets are weighed, packaged, and checked by hand. I overheard one employee say that they had a few thousand bullets to weight-sort before they could be packaged because they feared something may have been slightly off during production. That was a time-consuming task, but they did weight-sort bullet by bullet to make sure nothing had gone wrong.
New Product Packaging
Berger is now offering “quantity packaging” for the most popular bullets in a number of different calibers. I was also surprised to see boxes in colors other than yellow on Berger’s shelves. Michelle explained to me that the yellow boxes are retained for match or target bullets. The thinner-jacketed hunting bullets now go in orange boxes while moly-coated bullets are packed in black boxes.
One last point worth noting is that if, like me, you (foolishly) wear a Sierra shirt to a tour of Berger Bullets, you will promptly be given a Berger shirt and hat to wear during the visit.
Michelle, thanks so much for the tour! — Kelly Bachand

Sam Hall of Boonville, North Carolina is “King of the Hill” when it comes to the 600-yard benchrest game. He is the 2009 IBS 600-yard Shooter of the Year, and he won the IBS 600-yard Nationals two years in a row. When Sam talks, people listen… if they’re smart. Sam was recently asked to compare the performance of Berger’s 6mm 108gr boattail vs. Berger’s 105gr VLD bullet. As Sam explains, both bullets have the potential to shoot really well, so your barrel and the conditions may dictate which projectile works best.
Berger 105gr VLDs vs. Berger 108gr BT by Sam Hall
I shot the 108gr Bergers (and 108 BT BIBs for a few matches) all last year in my Light Gun (LG) and Heavy Gun (HG) in 600-yard IBS competition, but switched to Berger VLDs during the Nationals because of the extreme winds in South Dakota.
When I started loading for the 108s, I quickly learned they are much easier to tune than VLDs. In the two barrels in which I shot the 108s, they did not seem to be sensitive to seating depth or powder charge like the 105 VLDs. I could not see much difference in groups at 600 yards during tuning. But, with the 108s, you will need to drop about one grain in powder compared to the VLDs due to longer bearing surface and extra weight. It seemed that the 108s show a consistent round-pattern group, where the VLDs many times have flyers. By this I mean, if both the 108s and 105 VLDs shoot a two-inch, 5-shot group at 600, the 108s will be evenly distributed in the two-inch circle. Conversely, the time the VLD’s will often have 3 or 4 shots in one inch but 1 or 2 flyers expanding the group to two inches. But when the VLDs don’t have a flyer, look out! That’s when most of the World Records have been set and VLD shooters have come from behind and won the match. (Yes, I am talking to you Mike Davis).
Mike Davis and I talked about the Berger 108s vs. 105s last year. The 108gr BTs are great until the wind gets up. They seem to get blown around more than the VLDs. A half-inch extra at 600 yards these days means the difference between winning or ending up middle of the pack. So, ideally, a shooter would have two loads. One would use the 108s for mild days, and the second would use the 105gr VLDs for those windy days.
If you don’t have time to tune the 105gr VLDs (tuning them can be difficult and time-consuming), I suggest you stick to the 108s. They will save you a lot of headaches and will stick close to the VLDs in most conditions.
How Temp and Humidity Affect Performance
I almost forgot to mention. As the temperature and humidity got up in the summertime last year in North Carolina, the 108s did not perform for me as well as they did during the cooler, less humid months. I tried developing a new, hot-weather load for the 108s, but I never got the 108s to perform as well in the summer as I did in the winter and spring — even when there was no wind. I don’t know why the 108s prefer cooler, less humid conditions, except maybe because they have more drag than the 105gr VLDs. High humidity may have had more of an effect on the 108s than we’d expect from the slight BC difference between the two bullets. The VLDs seem to drill through the wind and humidity better than the 108gr Bergers. NOTE: These findings are my own opinion based on many, many groups shot tuning and in competiton, while using several barrels of various manufacturers.
I hope this helps and does not further complicate your load development process. Try both bullets before you buy a large quantity of bullets. Your rifle will let you know which projectile it prefers. We have often found that a particular barrel will shoot one bullet design well but not the other. A few barrels will shoot BOTH bullet types really well.”
