“Ultimate PPC” by Speedy with engraved Stiller Viper action. Titanium Rest by John Loh (R.I.P.).
 Just in time for Christmas, today we feature a beautiful red rifle built by West Texas gunsmith Thomas “Speedy” Gonzalez many seasons back. With an eye-catching, one-of-a-kind engraved Stiller Viper action, and gorgeous red/black gelcoat finish, we think this rifle is one of the prettiest benchrest rigs ever made — and the color scheme fits the holiday season.
When Speedy set out to build the “ultimate PPC” for his own use, he wanted it to be as handsome as it was accurate. This stunning 6 PPC combines some very trick components with old-world detailing. When was the last time you saw an engraved receiver on a “race gun”? This rig combines modern high-tech components with classic good looks — the best of both worlds.
This competition benchrest rig features an engraved Stiller Viper action, with integral scope rail, SAKO Extractor and non-fluted bolt. The action sits in a new Millenium BR-X carbon-fiber stock built by Robertson Composites (now closed). The bold red-on-black marbled finish is how the gelcoat came from Ian Robertson’s factory — the stock has not been painted. The slick front rest is a titanium Ultra-Rest machined by the late, great John Loh with design input by Speedy. John built only two of these in titanium, one for himself and one for Speedy. We’re sad to say John recently passed. R.I.P. John. The Leupold Competition scope sits in quad-screw bedded rings from S.G.& Y. Precision Rifles.
Speedy picked a very special barrel for this project–a 1:14 twist, 20.5″, 6-groove barrel, the last original Pat McMillan-crafted barrel in Speedy’s inventory. Speedy runs a .263″ neck. Bushing size depends on the load and the condition of his brass. Speedy’s match load is about 29.2 grains of the IMR 8208 “ThunderBird” powder (he stockpiled this great propellant years ago). Speedy feels that T-Bird may be the most user-friendly BR powder ever made: “Once you have a good load worked up with T-Bird, you can shoot it at most any location in the country, and in almost any conditions. It’s not fussy about temperatures or humidity.”
A Very Unique Viper Action, Two Years in the Making
This is no ordinary Viper action. The full engraving attracts your attention, but there are some slick “performance mods” Jerry Stiller added at Speedy’s request.
 First, the action features a plain-Jane unfluted bolt, with a slight taper in the middle, a bit of a wasp-waist. Speedy prefers an unfluted design because it has superior wear characteristics. He’s found, when working with an aluminum action such as the Viper, the sharp flutes on the bolt will wear the inside of the action faster. In the interest of reduced wear, Speedy also requested a smaller-sized loading/ejection port. This provides for a larger front and rear receiver ring, which enhances bolt bearing surface. More bearing surface reduces point loading for less internal wear.
We were surprised that Speedy did not order a drop port for his Viper. He explained: “I’m a bag squeezer, so I keep my forearm right where the cases would exit the drop port. I’ve used the drop ports, but given my shooting style, I prefer a conventional port.” Speedy did decide to fit the bolt with a SAKO-style extractor. He believes this is easier to tune and can contribute to accuracy. Speedy told us: “With a conventional sliding plate extractor, like you find on the Stolle actions, there can be a bit of a side push as you chamber the round. I think this can affect the way the bullet enters the chamber. With the SAKO extractor there is no side-push so I can reduce the possibility of bullet misalignment.”
BR-X Stock — American Design, Canadian Craftsmanship
The BR-X carbon fiber stock represents a third-generation design. The original Millenium, built by Lee Six, was a hollow shell. This modern BR-X is carbon fiber over a foam core. In Light Varmint trim, it weighs just 1.5 pounds. Speedy tells us: “this BR-X has a low center of gravity, slight pistol grip, and the angles are really straight and true. It tracks well in the bags, and won’t lift out of the rear bag during recoil. That’s one of the purposes of the wedge-shaped rear section.”
Speedy looked at the various benchrest stocks, and, with input from Tony Boyer, he worked out a design that mirrored many of the better features of existing designs with some significant enhancements. The first thing you’ll notice is that the geometry is very uniform. The flats on the side of the fore-arm are perfectly parallel. The underside of the fore-arm is seamless and completely flat. Speedy explained “one problem we’ve seen with stocks that have a mold seam in the middle is that sometimes the two halves of the mold don’t mate perfectly. Sometimes the mold is mismatched so one side is on a different plane. That creates all kinds of handling issues. If the bottom of the stock is convex, even a little bit, you lose a lot of stability.”
 Much thought went into the rear section of the stock. Speedy and Tony found that many stocks would start off tracking well, but by the end of the string they were pulling themselves out of alignment. Speedy noted that with some more conventional designs, they tended to ride up out of the rear bag after two or three shots. The BR-X works differently. It uses a wedge design, rather than a radius, so it tends to drive itself down into the bag on recoil. The BR-X is not the only stock to use a wedge in the rear, but it is different than other wedge designs. According to Speedy: “On most other wedge stocks, the wedge tapers towards the pistol grip, making the ‘V’ wider towards the end of the buttstock. This will change point of aim as the stock moves. The BR-X has a wedge that is a constant ‘V’, with no taper from the end to the pistol grip. This does make the gun track better and stay on target better.”
Competition Benchrest Terminology
Bughole: Very small group.
Mothball: The 10-ring on the standard Benchrest Target.
Tomato Stake: A worn out or otherwise inaccurate rifle barrel.
Screamer: A group measuring less than 0.100″ at 100 yards or less than 0.250” at 200 yards.
Weather Report: A Group “scattered” as a result of poor wind doping.
Wailing Wall: Place where targets that have been scored can be viewed by competitors.
Dope the Wind: Ccompensate for the effects of wind by shifting aiming points on the target.
Barrels–The Hunt for a ‘Hummer’
Top 6 PPC competitors often run through a number of barrels in the quest for a “hummer” that performs optimally. In addition to the Pat McMillen tube on this gun, Speedy uses barrels from Hart, Krieger, and Shilen. He’s tried a few from some other boutique barrel makers and they shot well, but he wasn’t satisfied with the barrel life. Some of them lost their competitive edge after just 500-600 rounds. He won’t name names in print, but you can call and ask. When choosing a barrel, Speedy recommends that you invest the time and call a few well-known smiths who regularly compete in high-level BR matches. Find out what’s working real well currently.
 Speedy says, “you can read the equipment lists from the big shoots, but the printed results can be deceiving. That winning barrel might have been produced a couple of years ago. Barrel-makers do have good runs and not-so-good runs. Do your homework and find out what’s working best right now.” Speedy prefers 6-groove barrels: “I’ve shot em all one time or another. It seems that the 6-groove barrels are easier to get to shoot. It seems at 200 yards bullets from a 4-groove barrel move more than from a 6-groove barrel. Both windage and elevation. I think Tony Boyer feels the same way.” [Editor’s Note: Speedy’s groove observations were made many seasons ago. Today, many top shooters are using 4-groove and 5-groove barrels, and 3-grooves have been successful in score competition.]
We asked about Speedy’s signature “SpiderWeb finish”. While the web design has esthetic appeal, there is a functional side as well: “Tests have shown that a bead-blasted barrel will shed heat faster than a highly polished barrel. With the SpiderWeb, we leave most of the bead-blast finish on the barrel, but the web effect gives the tube some visual appeal.”
Speedy Speaks — How to Succeed in Benchrest Competition
Let me begin by saying that benchrest competition is the most difficult sport I’ve ever tried. For the newcomer, it can be daunting. From the very word “go” you are thrown to the wolves. Most new competitors have about a two and a half or three-year window. After that, if they are not meeting their expectations, they get fed up and leave the sport. Considering the time, effort, and money they may have expended in that time, that’s an unfortunate outcome.
 So, how does one improve as a shooter and get to the point where you are meeting your goals? First you need to break down the shooting process into its parts–gun handling, loading technique, wind awareness, time management, bag set-up, and what I call ‘bench management’. Then you need a mentor. Benchrest is like golf–you can have the best equipment (best action, best stock, best rest) but you won’t get far without a knowledgeable veteran to monitor your progress and observe your technique. Without a mentor, benchrest is a rough game to play and you can reach a frustration point after a couple of years.
If you don’t have somebody who can sit and evaluate your loading style, bolt-working, follow-through, and wind-reading etc., you can develop bad habits that are hard to break. If there’s no one to monitor your shooting and see what you’re doing wrong, you’ll keep making the same mistakes. So how does one find a mentor? Well it’s not a bad idea to attend one of the shooting schools. But one-on-one training is best. Look for someone with a strong record in competition, but a person who is also patient. And when you find that person, show some loyalty. With most people who have been involved in the sport a while, if you show them allegiance, they will return that allegiance.
6mm PPC Basics — About the Cartridge
 Developed by Louis Palmisano and Ferris Pindell (left and right in photo), the 6 PPC is the “King of the Hill” in short-range benchrest competition, the most accurate cartridge ever invented. It still completely dominates 100- and 200-yard Group BR Shooting. If you want to win in that game, you pretty much have to shoot a 6 PPC, or some close variant of the 6 PPC cartridge design.
Easily made from Lapua 220 Russian brass, the 6mm PPC has a small primer and small flash hole. The small flash hole/primer accounts for much of the 6 PPC’s superior accuracy, though nobody really knows precisely how or why. The “short, fat” shape and nearly straight body contribute to efficient, consistent combustion and good “chamber behavior”.
While SAKO has created an official SAAMI 6mm PPC round, called the 6PPC USA, most American 6 PPC shooters run tight match chambers cut with custom reamers. There will be variations from one reamer to another, enough so that custom dies are generally recommended for match guns. Here is a PT&G reamer spec’d by Speedy a while back. He prefers a .263″ neck because that works better than .262″ when he needs to use his tightest bushings to get more neck tension.
The 6 PPC’s case capacity, case size to bore ratio, and combustion properties seem to be just about ideal for the short 6mm match bullets. A 6BR can come close, but when the goal is shooting “zero” groups at 100 and 200 yards, the 6 PPC is the clear winner. Currently most 6 PPC shooters form their cases from Lapua 220 Russian brass. Norma also makes factory-formed 6 PPC cases, but Norma brass is not commonly used as most shooters believe it is less “tough” than Lapua brass and accordingly won’t last as long with very stout match loads.

February 5th, 2019
This week we return to our 6mmBR.com roots with an article on David Bergen’s slick 24″ Drop-Port Viper. This was one of the first 6BR rifles we featured. David, who hails from Belgium, developed this project over many months, and the gun proved to be a true tack-driver, with the ability to group in the Ones, even with the heavy boat-tail bullets. David talks about the build and his reloading methods while action designer Jerry Stiller provides technical insights into the design features of his Viper action.
It was a long journey looking for the perfect custom action to build my new rifle. I searched the internet and visited various forums. I even re-read all my old Precision Shooting magazines to find what I was looking for. One evening I conferred by telephone with Mr. Jerry Stiller of Stiller’s Actions in Texas. He patiently answered all my questions. That moment I decided that I wanted a Viper Drop-Port action. [Editor: Sadly, the Viper Drop-Port is no longer in production.]
Component Selection
At the heart of this gun is a Viper action. This medium-sized action can handle cartridges from a small BR up to a 6.5-284. (Stiller’s smaller Cobra action is for PPC and BRs only.) The Viper is milled from aluminum. This keeps weight down while still allowing Vipers to have a large bedding surface like a Stolle Panda.
At first I was a bit sceptical about the aluminum’s toughness, but Mr. Stiller informed me that the action is the perfect marriage between steel and aluminum. The bolt is hard-chromed and the action body is hard-anodized. This gives it two surfaces that resist wear and make an already-slick action even slicker. Stainless steel is used for all the heavy-stress points including barrel threads, locking lugs, and the rear camming surface. The bolt is made of steel with a very light, small-diameter firing pin to prevent primer piercing with heavy loads. Everything is held very concentric to the bore axis. The Viper is a very smooth action mainly because the design and the precise machining of the camming surfaces. Combined with optimal bolt-lift timing, this gives a smooth action. Stiller also keeps the tolerances very tight on these actions, though they are as fast-handling as any you can buy. The trigger is of course a Jewell BR model.
The rifle is chambered in 6mmBR Norma, my favorite cartridge. I have two HV-contour Shilen match barrels, both with 1 in 8″ twists and finished lengths of 24 inches. The chamber has a .266″ neck so neck-turning is necessary. Freebore is .060″ but combined with a 1.5° throat angle this lets me seat a wide range of bullets from 58 grains up to 107 grains.
The stock is a McMillan Edge with moulded-in gray and black marble swirl. I specified 60% black and dark and light gray both at 20%. I went with the Edge stock because I was always pleased with McMillan products and because it had a very low center of gravity. I wanted the barrels very low in the stock because I think it makes the gun track better.
 Details of the Drop-Port–with VIDEO!
The visible part of the Drop-Port is a cartridge-sized cut-out in the floor of the action. This tapers into a funnel shape that lets the spent case fall nose-first through a single hole in the underside of the stock. The Drop-Port is carefully sized so that empty brass will fall through from gravity but a loaded round won’t. I’ve found that getting a BR case to eject 100% reliably in a standard action is not easy. The round is short and fat so it clears the chamber too early and the ejector pushes the cases out the extractor too fast. This can result in an empty case sitting in your action, no longer held by the extractor. Needless to say, this can slow you down during a stressful competition. When you get a Drop-Port you can forget all those problems.
Failure to eject is NOT going to happen with a Drop-Port. The system just works every time, and it’s FAST. Right-Click on the Media Player image and “Save As” to download a video (6.9 megs) showing me cycling the action during live fire.
One smart feature of the Drop-Port is the extractor location. A Remington extractor is located at the bottom of the bolt. This way the case is supported by the extractor until the front of the case lines up with the cut-out in the action. At that moment the front of the case tilts down and the rim slips out of the extractor. In the stock there is a funnel which collects the case. The case drops out of the rifle through a single small hole in front of the trigger guard.
 Building an Accurate Load
Tools and Recipes
I start with new Lapua cases and after full-length sizing I trim them with a Wilson trimmer. Then I turn the necks for a .264″ neck diameter with a Lapua 105 seated in the brass. After fire-forming I use a “semi-custom” Harrell’s full-length sizing die with bushing. I use a .262 bushing with the moly-coated bullets. This Harrell’s die is the best I ever used — it gives very low run out. [Editor’s Note: Harrell’s stocks a number of dies with various internal dimensions. You send them three fire-formed cases and they’ll pick out a die that fits your brass the best. The cost is very reasonable.] Overall the excellent concentricity I’m seeing with my rounds is a combination of a superb chambering job, a neck-turned Lapua case and the Harrell’s sizing die. The die is supplied with a brass bushing that allows you to measure the amount of sizing you are doing.
For seating I use both a Wilson inline seater (hand die) and a Forster seating die that threads into a press. The latter gets the most use because I find it easier to use. Run out with both is around 0.001″ or better measured on the bullet.
Load development was very easy. I started with Varget and all loads … shot well. Vihtavuori N150 also shot very well with… moly-coated Lapua 105s. To my delight, the light bullets are also shooting very well in the 1:8″ twist. Nosler Ballistic Tips are giving very good results with a case full of N140. I’ve also tried N150, N540 and AA 2520. For all loads I’ve been using CCI BR4. Bullets are seated well into the lands with square marks showing. This gives an overall length around 59 mm (2.32″), depending on the bullet used.
 Shooting the Rifle–How It Performs
The rifle is very easy to shoot and it is very accurate, but it had some drawbacks in the beginning. First there is the stock. It is designed for bench shooting and on a table it does this very well. I use a Caldwell front rest and a Protektor rear bag. When shooting prone I’ll also use the rest but the cheek weld is not ideal (the Edge was optimized for free recoil shooting from the bench). The rings that are supplied with the action are rather high. I looked around and found some that were lower. This made shooting easier, but I still wasn’t satisfied. The gun was a bit nose-heavy. There is a weight system built into the stock, but it wasn’t enough to bring the gun in balance. I like the balance point to be just in front of the receiver ring. So I cut the rear off the stock and put in a larger tube and turned some weights to put in it. I also made up an aluminum butt plate. Then I installed a Harrell’s brake to cut recoil to a minimum. With these modifications, the rifle is now shooting the way I want. I think the Edge stock is a very good design for benchrest shooting but for prone shooting it has some shortcomings. I think the MBR is a better stock for shooting prone.
Muzzle Brake–Less Recoil, Same Excellent Accuracy
After testing the barrel with different loads, I decided to put a brake on one barrel. Most of my guns are muzzle-braked and since I had two virtually identical barrels, I put a Harrell’s brake on one. The barrel had to be threaded to mount the brake and here I was a little concerned–I remembered the advice to “never mess with a winner”. The un-braked barrel was ultra-accurate and I was curious whether the process of fitting the brake might affect the accuracy.
Thankfully, my worries were unfounded. My targets showed no loss of accuracy — there was no evidence that the brake had caused any changes (except as to recoil). I have wondered though, perhaps the brake makes the gun more shootable and in that way compensates for some small accuracy loss that may be there? Whatever the case, the gun shoots just as tight as before, except now it’s a lot more user-friendly with less muzzle hop and less “push” on recoil.
 This Rifle Literally Shoots Bug-Holes
And now I come to the end of the story. One day when testing the rifle at 100 meters (with brake installed), I spied a fly on the target. Well now, I thought, here is an interesting “precision shooting” challenge. I put the crosshair on the fly, squeezed the trigger, and the fly was history.
One shot, one kill. Now THAT is impressive precision. If you look closely you’ll see what’s left of Mr. Fly around the bullet hole. Or “bug-hole” as you Americans would say. This kind of performance is a real confidence-booster for the trigger-puller, let me tell you.
The Drop-Port — Simple Yet Advanced
Jerry Stiller tells us: “The drop-port ejects the case out the bottom of the action using only gravity. No ejector plunger is required so the system is as foolproof as anything can be. (A normal spring-loaded ejector creates an uneven load on one side of the case head.) Unlike other ejection systems, micro-ports etc., a Drop-Port doesn’t require tuning or adjusting, and just works. Many top shooters tell us they can cycle rounds faster with a Drop-Port action than with any other design.”
“The engineering of the Viper reflects some key design objectives. I wanted it to be able to fit standard commercially available stocks and have a barrel fit-up that was well known in the industry. I liked the idea of the larger bedding area and higher stiffness of the aluminum actions, so I chose the Panda footprint and barrel tenon for the Viper. I also made some changes to what was available at the time to make the product better. I used a smaller diameter firing pin to eliminate primer piercing, hard anodized all the aluminum parts for corrosion resistance and to make the surface hard and slick. The bolts are also coated for the same reasons.

July 18th, 2011
 Montana 1K benchrest shooter Leo Anderson has set a pair of astounding multi-match Light Gun Score Agg records. These are “records for the ages”. This season, Leo’s 6-match Score Aggregate was 99.5 (99,99,99,100,100,100), while his 10-match Score Aggregate was 96.8 (84,94,95,98,99,99,99,100,100,100). That’s amazing consistency. Given how hard it is to shoot a single 100 score at 1000 yards, Leo’s Aggs are jaw-dropping. It will be a long time before these Agg records are broken (if they ever are). Leo set his 99.5 (6-match) and 96.8 (10-match) records shooting a 17-lb rifle chambered for the 6mm Dasher. The Lawrence barrel was chambered by Montana gunsmith John King and Leo did the stock work himself (starting with a Shehane MBR Tracker).
99.5 Six-Match Agg and 96.5 Ten-Match Agg at 1000 Yards
Leo set these multi-match Agg records at the Deep Creek Range near Missoula, Montana. Tom Mousel, another record-holding Montana shooter reports: “Our Agg season is now complete here in Montana. Leo ‘Legend’ Anderson has broken both the 6-match and 10-match score aggregate records. He hasn’t just broken them, he has smashed them, with a couple Aggs that are truly remarkable. As a fellow 1000-yard competitor, I fully understand what it takes to grind out a quality Aggregate. What Leo has done this year is the most impressive thing I think we might ever see in the 1000-yard benchrest game. Leo is one of the best of the ‘good guys’, and also, in my opinion, Leo is the best 1000-yard shooter to ever grace our sport. You’d have to check with Leo, but I believe these are his 14th and 15th world records in his career. Leo also holds our Club record for Light Gun group and score, when he drilled a 3.476″/100 back in August of 2008″. (See photo below)
Record-Breaking 6mm Dasher Light Gun Specs
There’s nothing really exotic about the 17-lb Light Gun with which Leo set his score records. The stock is a laminated Shehane MBR Tracker with some modifications by Leo to make it track better. Leo altered the angle of the toe to match the forearm and modified the taper of the sides of the buttstock to ride better in the bags. Pillar-bedded into the stock is a Stiller Viper Drop Port. Leo loves this action. He says it is very fast to operate and the flat bottom makes it easy to install in the stock. In addition, the Viper action works well with his preferred CCI 400 primers: “I can run stout loads of H4895 with the Viper without cratering the primers. Some guys with other factory and custom actions have problems with the CCI 400s which are not as hard as the 450s.”
The 29.5″, 5-groove, 0.237″ land, HV-counter barrel was crafted by Lawrence Barrels. Based in Lewiston, Montana, Lawrence Barrels currently makes mostly AR barrels, but Leo says they make great cut-rifled tubes: “I currently have Lawrence barrels on both my Light Gun and my Heavy Gun. These Lawrence barrels both shoot great. I think they are the equal of the best examples from top barrel-makers such as Krieger and Bartlein.” Leo has tried straight-contour barrels, but he prefers some taper (similar to a Krieger #17 contour): “In my experience, tapered barrels seem to shoot better, at least in a 17-pounder. The gun is less nose-heavy and tracks better.” The barrel on Leo’s record-setting Light Gun currently has about 900 rounds through it.
For optics, Leo runs a 12-42x56mm Nightforce BR model with NP2DD reticle. Leo tells us: “the NP2DD reticle is my favorite and I have great confidence in the Nightforce. We tried it side-by-side with a big name European-made high magnification scope, and the Nightforce was visibly better. At 1000 yards it had better clarity, better sharpness, better resolution.”
Record Setting Dasher Recipe: Berger 105gr VLD, Hodgdon H4895, CCI 400, Lapua Brass
While many top 6mmBR and Dasher shooters use Varget or Reloder 15, Leo prefers Hodgdon H4895, which has a slightly faster burn rate. Leo tells us: “Right now, the H4895 and CCI combo is giving the best accuracy, and it’s a clean combination. I’ve shot a lot of Reloder 15, but the H4895 burns so much cleaner.” Leo’s load is running around 3050 fps, but “he’s not too concerned with what the chronograph says — when we tune our loads we go by what shows up on the target.” Leo is loading a bit more than 32 grains of H4895. (Editor’s NOTE: This load is for fully fire-formed Dasher cases ONLY. It is NOT safe to use in a 6mmbr with 105s.) Leo’s favorite projectiles are the “thin-jacket” Berger 105gr VLDs, pointed with a Whidden pointing tool. Leo turns his necks with a K&M neck turner.
To save on barrel life, Leo fire-forms his brass using a separate barrel. He prepares the brass with a false shoulder, then fires the cases loaded with pistol powder, cream of wheat and low-density plug in the end. He tried forming case with pistol powder alone, but that required much more powder and didn’t produce results as good as the cream of wheat method.
Shooting Fast — the Importance of Smooth Tracking
Leo tells us that you need a great-tracking rig to be competitive in the 1K game these days: “Some guys are getting 10 shots downrange in 20 seconds or less. It takes me about 30 seconds.” To shoot that fast, the gun needs to track perfectly so you can just slide it back and stay on target. “If you want to shoot fast, everything’s got to be working right — and your stock really needs to track well. If you’re chasing the knobs on your rest, you’re not getting [your bullets] down range.” Leo says the stock’s geometry must be “near perfect” in order for the gun to come back to the same spot shot after shot.
Leo Anderson’s Advice for New Long-Range Shooters.
We asked Leo if he had any advice for shooters new to the long-range benchrest game. Here are some of his thoughts:
1. Pick a Winning Cartridge – Leo thinks the Dasher is just about perfect for a 17-lb rifle: “Any more cartridge than that, you have too much gun movement. Something in the Dasher range is the perfect size. We shoot the Dashers around the 3050 fps node. Even with the 6-6.5×47 you’re just burning more powder, and at the higher node, the gun starts rocking and things start getting away from you.”
2. Get Good Equipment Right from the Start – “Go ahead and bite the bullet and buy good stuff right off. Too many guys try to get off cheap in the beginning. They end up buying two or three guns as they upgrade. You save money in the long run by buying good stuff in the beginning.”
3. Practice, Practice, Practice – “We get a lot of practice in the process of tuning and load development. We put in the time — on things like bullet sorting, case prep, load tuning.”
4. Keep Pushing for Perfection – “A lot of guys get a load that seems pretty good, and then they get lazy. Don’t be content when you get a 6-inch group at 1000, because the gun might shoot a LOT better. I’ve got Aggs in the five-inch range.”
Leo reports: “Here’s our ‘secret’ 1000-yard range out in the sticks where we do some spring tuning”.
