Hail the King — Paul Phillips wears crown as the new 2019 King of Two Miles.

Paul Phillips, Captain of Team Global Precision Group (GPG), is the 2019 King of 2 Miles. Hail the new King! Paul won the event with a score of 48350, beating runner-up Robert Brantley who scored 46306. Fellow GPG shooter and 2017 K02M winner Derek Rodgers finished third with 38747. Phillips secured his K02M crown with good shooting in Raton, NM on both Day 1 and Day 2. On the final day, Paul had two hits at 2728 yards and one at 3166 yards. No competitor scored more than one hit at 3166 yards (1.799 miles), and no competitor scored even a single hit at the farthest target, placed at 3525 yards (2.0028 miles). So the actual 2-Mile target was never hit during the event.

Paul added: “Big shout-out to all our sponsors, the match organizers, Eduardo, FCSA, and the volunteers who work so hard to make these ELR matches a major success. We’ll definitely be back in 2020!”

“Paul Phillips your win in this match is yet another example of the value of hard work paying off. I can honestly say that I don’t know anyone who works harder at ELR competition and promotion than you do. You deserve this win!” — Bryan Litz, Applied Ballistics

Equipment List for .416 Barrett 2019 KO2M-Winning Rifle

Paul’s massive KO2M rig features a BAT EX .50-Cal action with a 38″ Bartlein 1:9″-twist 5R barrel chambered for the standard .416 Barrett cartridge. The stock is a McMillan Beast One model. To tame recoil, Paul runs a T5 Terminator muzzle brake. The scope is a Nightforce 7-35x56mm ATACR F1 with MOAR Reticle. Up front is a Phoenix Precision Bipod, with an Edgewood Mini-Gator Bag in the rear. Paul is running a Bix’N Andy Comp Trigger with a 4-ounce, single-stage pull.

The complete rifle weighs 40 pounds. Bartlein did the .416 Barrett chambering using a Dave Manson reamer. Alex Sitman bedded the action in the McMillan stock as he did for the other GPG rifles. In fact, all three Team GPG rifles are essentially identical.

Load Details: Standard .416 Barrett cartridge, running .416 Caliber 550gr solid Cutting Edge Bullets at 3000 fps. The powder is Vihtavuori 20N29 ignited by RWS .50 Caliber primers. The cartridge brass is Barrett brand, produced by RUAG.

Support Gear: Ballistics are calculated with Applied Ballistics Software using velocity data from a LabRadar chronograph. Swarovski provided Team GPG with two big BTX 95 binocular spotting scopes. Phillips says “these BTX 95s really help us follow trace, spot impacts, and get on target quickly.”

Tuner TECH — POI Shift with Barrel Tuner Position Changes

Tuner Pascal Bukys Point of Impact shift test 6 PPC benchrest

6PPC Pascal Fischbach Bukys Barrel Tuner sine waveHave a good look at the photos below — this may be one of the most noteworthy target strings we’ve ever published. What you can see is the effect of barrel tuner position on point of impact (POI). You can clearly see that the tuner position alters the up/down POI location in a predictable fashion.

This remarkable 15-shot sequence was shot by French benchrester Pascal Fischbach using his 6 PPC fitted with a CG (Carlito Gonzales) action and a Bukys barrel tuner.

Pascal reports: “After [bullet] seating and load validation, I put the Bukys tuner on, screwing it out 10 turns. According to Carlito, the CG’s super stiff action-to-barrel fit gives a faster vibration modulus that is detrimental below 10 turns [position of the tuner].” Pascal’s procedure was to screw out the tuner 1/4 turn progressively from one shot to the next. He shot one bullet at each tuner position, with a total of 15 shots.

Pascal observed: “Note the point of impact displacement [from shot to shot] tracks clearly along a sinusoide (sine wave curve).” This is indeed notable and significant! This shows how the tuner’s ability to change barrel harmonics can alter the position of the muzzle as each bullet exits, resulting in a higher or lower POI. Pascal sent his results to Carlito Gonzales in Argentina for analysis.

Pascal poses this question to readers: “Guess which three positions Carlito recommends to try?”

Editor’s Note: While this target sequence clearly shows how tuner position can alter bullet point of impact, this, by itself, does not tell us which tuner position(s) are best for accuracy. That will require further multi-shot group testing, involving careful experimentation with tuner position (and powder charge weights). But for those folks who doubt that a tuner can make a difference on a short, fat barrel, just take another look at the photos. The up/down changes are undeniable, and noteworthy in the wave pattern they follow.

Shooting Set-up and Test Conditions:
Pascal did this test at an outdoor range under very good conditions: “This was shot at my home range, outdoors, with four Smiley flags. The range is a narrow cut in high woods. Wind was consistent with readable flags. I started testing the tuner from 10 turns out and on to 15. I recently… found a sweet spot very close to the rearmost position of the tuner, so the rigidity provided by this super long tenon (just short of 70mm) was not a reason to overlook the recommended Bukys tuning procedure.”

Figure Out Exact Barrel Weight with Pac-Nor Calculator

Online Pac-Nor Barrel Calculator

Can you guess what your next barrel will weigh? In many competition disciplines, “making weight” is a serious concern when putting together a new match rifle. A Light Varmint short-range Benchrest rifle cannot exceed 10.5 pounds including scope. An F-TR rifle is limited to 18 pounds, 2 oz. (8.25 kg) with bipod.

One of the heaviest items on most rifles is the barrel. If your barrel comes in much heavier than expected, it can boost the overall weight of the gun significantly. Then you may have to resort to cutting the barrel, or worse yet, re-barreling, to make weight for your class. In some cases, you can remove material from the stock to save weight, but if that’s not practical, the barrel will need to go on a diet. (As a last resort, you can try fitting a lighter scope.)

Is there a reliable way to predict, in advance, how much a finished barrel will weigh? The answer is “yes”. PAC-NOR Barreling of Brookings, Oregon has created a handy, web-based Barrel Weight Calculator. Just log on to Pac-Nor’s website and the calculator is free to use. Pac-Nor’s Barrel Weight Calculator is pretty sophisticated, with separate data fields for Shank Diameter, Barrel Length, Bore Diameter — even length and number of flutes. Punch in your numbers, and the Barrel Weight Calculator then automatically generates the weight for 16 different “standard” contours.

Calculator Handles Custom Contours
What about custom contours? Well the Pac-Nor Barrel Weight Calculator can handle those as well. The program allows input of eight different dimensional measurements taken along the barrel’s finished length, from breech to muzzle. You can use this “custom contour” feature when calculating the weight of another manufacturer’s barrel that doesn’t match any of Pac-Nor’s “standard” contours.

Caution: Same-Name Contours from Different Makers May Not be Exactly the Same
One final thing to remember when using the Barrel Weight Calculator is that not all “standard” contours are exactly the same, as produced by different barrel-makers. A Medium Palma contour from Pac-Nor may be slightly different dimensionally from a Krieger Medium Palma barrel. When using the Pac-Nor Barrel Weight Calculator to “spec out” the weight of a barrel from a different manufacturer, we recommend you get the exact dimensions from your barrel-maker. If these are different that Pac-Nor’s default dimensions, use the “custom contour” calculator fields to enter the true specs for your brand of barrel.

Smart Advice — Give Yourself Some Leeway
While Pac-Nor’s Barrel Weight Calculator is very precise (because barrel steel is quite uniform by volume), you will see some small variances in finished weight based on the final chambering process. The length of the threaded section (tenon) will vary from one action type to another. In addition, the size and shape of the chamber can make a difference in barrel weight, even with two barrels of the same nominal caliber. Even the type of crown can make a slight difference in overall weight. This means that the barrel your smith puts on your gun may end up slightly heavier or lighter than the Pac-Nor calculation. That’s not a fault of the program — it’s simply because the program isn’t set up to account for chamber volume or tenon length.

What does this mean? In practical terms — you should give yourself some “wiggle room” in your planned rifle build. Unless you’re able to shave weight from your stock, do NOT spec your gun at one or two ounces under max based on the Pac-Nor calculator output. That said, the Pac-Nor Barrel Weight Calculator is still a very helpful, important tool. When laying out the specs for a rifle in any weight-restricted class, you should always “run the numbers” through a weight calculator such as the one provided by Pac-Nor. This can avoid costly and frustrating problems down the road.
