H.R. 788 will help States build and maintain shooting ranges with Federal funding assistance.
Federal Legislation has been introduced that will help build and maintain shooting ranges. H.R. 788, the Target and Marksmanship Training Support Act of 2017, was introduced in Congress by Rep. Duncan Hunter (R-CA) and a bipartisan group of 23 co-sponsors. The provisions of H.R. 788 will help States fund public shooting ranges with Federal Firearms Excise tax revenues.
“This legislation [H.R. 788] would provide state fish and game agencies more flexibility to use Pittman Robertson excise taxes dollars raised from the sale of firearms and ammunition to enhance existing public shooting ranges and to build new ones to meet the growing need for additional places for target shooters to participate in their sport,” said Lawrence G. Keane, NSSF Senior V.P. and General Counsel. “Public shooting ranges provide hunters a place to sight-in rifles and shotguns before hunting seasons, for people to take firearm safety and hunter education courses, and for recreational target shooters to enjoy their sport.”
Since 1937 almost $11 billion has been raised for wildlife conservation through the Pittman-Robertson excise tax on the sale of firearms and ammunition. States are permitted to use some of those funds for hunter education courses and for public shooting ranges under a restrictive formula that has largely discouraged state agencies from building and enhancing public shooting ranges. H.R. 788 will help states use Pittman Robertson revenues by increasing the limit on Federal funding of shooting ranges from 75 to 90 percent. This means states could begin work on range facilities with 10 percent State-supplied funding, instead of the current 25 percent. It would also allow Federal Excise funds to be made available and accrue for five years for land acquisition or range construction.
In addition, the legislation would limit frivolous lawsuits arising from the use of Federal land for target practice and encourage Federal agencies to cooperate with state and local authorities for maintenance of ranges on federal lands.

Shown above is the Belfast Wildlife Area rifle range in Kindards, SC. Belfast was the first public, unmanned shooting range opened and paid for completely with funds raised by NRA Grants and the Wildlife and Sportfish Restoration Program … an act made possible through Pittman-Robertson grants. Several other state Natural Resource Departments have followed suit.
Legislative History: The Target and Marksmanship Training Support Act was previously introduced as H.R. 2406, the SHARE Act (Title II), and the Bipartisan Sportsmen’s Act in the last Congress, as well as a stand-alone bill H.R. 2463 in the 113th Congress.

If you’ve never visited the NRA Whittington Center outside Raton, New Mexico, it is well worth a visit. This new HD video shows the features of this unique facility where marksmen can shoot from 10 yards to two miles. Drone video footage gives you a “birds eye view” of the scenery and the ranges.
This is an excellent video. Well worth watching, with impressive aerial photography.
The Whittington Center hosts many major matches each year. Along with the training and range facilities, the Whittington Center has comfortable, modern cabins and RV camping zones for extended stays. Founded in 1973, the Center offers ranges for every kind of shooting discipline, along with a shotgun center, firearms museum, specialized firearms training, guided and unguided hunts, plus an adventure camp for younger shooters.

TT Freestyle’s Husband and Wife Borden Benchrest Rifles
Here’s a pair of “His and Hers” rigs delivered by Santa in December. Forum member TT Freestyle reports: “After our rookie year in Short Range Benchrest with good used equipment, my wife and I decided we liked it enough to get two new Bordens for Christmas!”
FalconPilot’s Fabulous F-Classer in Shurley Claro Walnut Stock
This beauty belongs to Forum member FalconPilot. He tells us that his “Lastest F-Classer features a Shurley Brothers SOD stock in beautiful Claro Walnut.” Components include Bat M action, Bix-N-Andy trigger, and Nightforce Comp scope. FalconPilot has several barrels for this Open-Class rig, including tubes chambered for .284 Win and 6mm Dasher.
Eric’s Blacktical .308 Win for Precision Rifle Series
Forum member Eric32 spent months building out this rifle, “getting it to work just right for PRS”. Designed for practical/tactical matches, this rugged rig features a blue-printed Rem 700 action (with 1.5-lb 40X trigger) in an XLR Element chassis. On the end of the .308 Bartlein 5R barrel is a JP brake. Other components include: PiG skins barricade grips, Atlas Bipod, and GGG bungee sling. On top is a SWFA HD 5-20x50mm optic with Vortex scope level and custom throw-lever.
Forum member Willow reports: “Here is my new F-Open gun. It features a hydro-dipped LowBoy stock and LH Barnard Model P action with ‘V’ bedding block. The barrel is a straight profile 32″, 1:8.5″ twist Bartlein 5R, chambered in 280AI by Matt Paroz”. On top is a Vortex 10-60x52mm Golden Eagle in a Spuhr 3001 mount. Willow says his lightning bolt rig is a shooter: “After 42 rounds through the barrel, I’m liking what I am seeing so far”. Check out that trick aluminum base for his rear Edgewood bag.
Stinnett’s 6.4×47 Lapua Tactical Rig
Forum member Stinnett tells us: “This is my third 6.5×47 Lapua rifle — the 6.5×47 is the best cartridge ever! I’m not a huge fan of muzzle brakes. I look at them as tools — use the correct tool for the job. The ’47 doesn’t need a brake. .308 Winchester and up need muzzle brakes. For this rifle, I’m going to start out with 123gr Scenars and Reloder 15. I also like to shoot the 123gr SMKs and Varget. The SMKs are much less seating-depth sensitive. Very easy to find a load! Also gonna try the Berger 130 Hybrids and H4350.”
Components: McMillan A5 adjustable stock in GAP Camo, Stiller TAC 30 A/W action, Jewell HVR trigger, Badger bottom metal and DBM, Atlas Bipod, Nightforce NXS F1 3.5-15×50 with MLR 2.0 reticle. Metal has been Cerakoted graphite black.
6mm BRX Benchgun with Home-Made Cherry/Redheart Stock
You have to give credit to a guy who crafts his own custom wood stock. This 6mm BRX benchgun features a custom-built laminated stock featuring Cherry wood with vivid Redheart pieces on the sides and Redwood Burl on the buttplate. The front of the stock is 4″ wide. The action is a Benchrest Borden RBLP Right Eject unit, with custom titanium scope rings on top. Owner Erick C. is proud of this stock, saying it is “the best one I’ve built so far”. We agree it’s a beauty.

Many of our Forum members shoot an “improved” 6mmBR cartridge. This might be a 30°-shoulder 6mm BRX, or a 40°-shoulder 6mm Dasher, or the 6mm BRDX, which is very similar to the Dasher, but with a slightly longer neck. This Editor shoots a 6mm BRDX and has found it very accurate, and maybe a bit easier to fire-form than a standard Dasher. Speaking of fire-forming, in our Shooters’ Forum, we often see questions about fire-forming BRX/Dasher brass. For those who need a large number of BRX or Dasher cases, one option to consider is using pistol powder in a dedicated fire-forming barrel. Here’s an explanation of how this process can work.
Forum member Skeeter has a 6mm Dasher falling block varmint rifle. The Dasher case is based on the 6mmBR Norma cartridge with the shoulder blown forward about 0.100″ and out to 40°. This gives the Dasher roughly 3.5 grains added capacity compared to the standard 6BR.
A few seasons back, Skeeter needed to form 300 cases for varmint holiday. Skeeter decided to fire-form his brass without bullets. This method avoids barrel wear and saves on components. There are various ways to do this, but Skeeter chose a method using pistol/shotgun powder, some tissue to hold the powder in place, Cream of Wheat filled to within an 1/8″ of top of the neck, and a “plug” of tissue paper to hold it all in place. Shown below are cases filled with a pistol/shotgun powder charge topped with Cream of Wheat and then a tissue paper plug.
To ensure the case headspaced firmly in his Dasher chamber, Skeeter created a “false shoulder” where the new neck-shoulder junction would be after fire-forming. After chamfering his case mouths, Skeeter necked up all his cases with a 0.257″ mandrel (one caliber oversized). Then he used a bushing neck-sizing die to bring the top half of the neck back down to 0.267″ to fit his 0.269″ chamber. The photo below shows how the false shoulder is created.
After creating the false shoulder, Skeeter chambered the cases in his rifle to ensure he could close the bolt and that he had a good “crush fit” on the false shoulder, ensuring proper headspace. All went well.
The next step was determining the optimal load of pistol powder. Among a variety of powders available, Skeeter chose Hodgdon Titewad as it is relatively inexpensive and burns clean. The goal was to find just the right amount of Titewad that would blow the shoulder forward sufficiently. Skeeter wanted to minimize the amount of powder used and work at a pressure that was safe for his falling block action.
Working incrementally, Skeeter started at 5.0 grains of Titewad, working up in 0.5 grain increments. As you can see, the 5.0 grain charge blew the shoulder forward, but left it a hemispherical shape. At about 7.0 grains of Titewad, the edge of the shoulder and case body was shaping up. Skeeter decided that 8.5 grains of Titewad was the “sweet spot”. He tried higher charges, but the shoulder didn’t really form up any better. It will take another firing or two, with a normal match load of rifle powder and a bullet seated, to really sharpen up the shoulders. Be sure to click on the “View Larger Image” link to get a good view of the cases.
The process proved to be a success. Skeeter now has hundreds of fire-formed Dasher cases and he hasn’t had to put one bullet through his nice, new match-grade barrel. The “bulletless” Cream of Wheat method allowed him to fire-form in a tight-necked barrel without neck-turning the brass first. The only step now remaining is to turn the newly Dasher-length necks down about .0025″ to fit his 0.269″ chamber. (To have no-turn necks he would need an 0.271″ or 0.272″ chamber).
Skeeter didn’t lose a single case: “As for the fire-forming loads, I had zero split cases and no signs of pressure in 325 cases fire-formed. Nor did I have any misfires or any that disbursed COW into the action of the firearm. So the COW method really worked out great for me and saved me a lot of money in powder and bullets.”
Skeeter did have a fire-forming barrel, but it was reamed with a .269 chamber like his 10-twist Krieger “good” barrel. If he fire-formed with bullets, he would have to turn all 300 necks to .267″ BEFORE fire-forming so that loaded rounds would fit in the chamber. Judging just how far to turn is problematic. There’s no need to turn the lower part of the neck that will eventually become shoulder–but how far down the neck to turn is the issue. By fire-forming without bullets now he only has to turn about half the original neck length, and he knows exactly how far to go.

2021 Update: This product has been discontinued, but may still be available at some retailers. But it cannot be purchased on Amazon.com.
Wouldn’t it be cool if your gun case could do double-duty as a shooting mat? That would be smart — you’d have one less item to carry to the range. Well such a thing does exist. Uncle Mike’s Long Range Tactical Bag protects your rifle during transport, then quickly and easily converts to a 78″ shooting mat. Measuring 50″ in length, with a 15″-tall main compartment, this bag is big enough to handle most tactical and F-TR rifles with optics and Harris-type bipods attached. A 30″ flip-out forward section includes a front load strap that allows shooters to pre-load the bipod legs while shooting prone.
The Long Range Shooting bag has four self-adjusting magazine pockets, which will hold magazine sizes from .223/5.56mm to .308/7.62mm. Conveniently, this new 50″-long soft case will fit inside the popular Pelican model 1750 hard case (for those situations where you need greater protection).

The 45th Annual Safari Club International (SCI) Convention is underway now at the Mandalay Bay Resort and Casino in Las Vegas, Nevada. The big event opened February 1st, and concludes Saturday the 4th. Over 20,000 hunters and sportsmen are expected to attend this year.
$10 Million in Auction Items This Year
The SCI show is famed for its fund-raising auctions. At this year’s Convention, over $10 million worth of exotic firearms, once-in-a-lifetime hunts, and fine collectibles will be auctioned. Net proceeds from the auctions are used by SCI to promote conservation and game management efforts worldwide. Here’s a past auction item, a Krieghoff Double Rifle valued at $84,000. This ‘Legends of the Hunt’ double rifle, chambered in .470 Nitro Express, is custom engraved by master engravers Michael Oke and Andreas Scholz. The stock is exhibition-grade Turkish walnut with ebony pistol grip and fore-end tip. There are gold barrel bands and gold accents on the express sight blades and double triggers.
Over 1000 Exhibitors from 33 Countries
This is a huge event, with over 1000 exhibitors from 33 countries and six continents. Notably, hundreds of top guides and outfitter services are showcased in the Outfitters Hall. The SCI convention also features many firearms manufacturers and custom gun builders. In the Gun Maker’s village prestigious European gun makers and engravers display their work.
The SCI convention boasts “the largest display of wildlife art at one venue anywhere in the world” according to Ammoland.com. The work of 55 artists and 110 taxidermists will be on display.
Hunt of a Lifetime — What Would You Hunt and Where?
A couple seasons back, Sierra Bullets asked its staffers about their dream hunting destinations. The Sierra techs, all avid hunters, were polled about their favorite hunting venues. Here are their answers to the question: “If you could hunt anything, anywhere in the world, where would you go and what would you hunt?”
Africa topped the list of “dream hunting locations” by a landslide. Canada and Alaska were both picked twice, with other destinations each favored by one staffer:
Africa 6 votes (Kudu, Eland, Cape Buffalo, Leopard, Lion, Plains Game)
Canada 2 votes (Moose, Black Bear)
Alaska 2 votes (Dall Sheep)
Wyoming 1 vote (Antelope)
US Rocky Mountains 1 vote (Elk)
Argentina 1 votes (Doves)
Australia 1 vote (Non-specific)
Carroll Pilant (Ballistics Technician): “Back to Africa for kudu and eland.”
Rich Machholz (Ballistic Technician): “African Cape Buffalo with my longtime friend Lloyd in Zimbabwee.”
Tommy Todd (Chief Ballistician): “Free Range African plains game”
Applied Ballistics has created a series of YouTube videos about precision long range shooting. Featuring ace long-range shooter and professional ballistician Bryan Litz, these videos will address various topics of interest to long-range marksmen. In this video, the first in the series, Bryan Litz answers the question, “Just What Is Long Range Shooting?” Bryan discusses how we define “long range” and the key factors shooters need to consider.
Applied Ballistics Video — What Is Long Range Shooting?
Bryan states: “I don’t think there is a clear definition of where Long Range starts.” But he offers this practical guideline: “The way I think of it, any time you’re making major adjustments to your zero in order to hit a target, due to gravity drop and wind deflection, THEN you’re getting into ‘Long Range’. For example, if you are zeroed at 100 yards and need to shoot to 600 yards, you have many feet of elevation [drop] to account for, and to me, that’s where it becomes Long Range.”
Extended Long Range and the Transonic Zone
Bryan adds a second concept, namely “Extended Long Range”. Litz says that: “Extended Long Range starts whenever the bullet slows to its transonic range. As the bullet slows down to approach Mach 1, it starts to encounter transonic effects, which are more complex and difficult to account for, compared to the supersonic range where the bullet is relatively well-behaved.” Bryan notes that bullets start to encounter transonic effects at about 1340 fps, quite a bit faster than the speed of sound, which is about 1116 fps at sea level in normal conditions (59° F).

This year, the Civilian Marksmanship Program (CMP) will offer a new Range Officer Training Program. This comprehensive training program will train and certify Range Officers for the CMP phases of the National Matches, CMP Travel (Regional) Games competitions, and CMP 3-position air rifle championships. The first objective of the new program is to train volunteers to serve as Range Officers in the 2017 National Matches. The course fee will be waived for National Matches volunteers.
CMP Chief Operating Officer Mark Johnson explained: “Knowledgeable, fair, effective Range Officers are absolutely essential… The CMP recognizes that the best way to make sure it has excellent Range Officers for its competitions is to train them.”
The CMP held the first-ever New England CMP Games event in 2016.
Range Officer Volunteers will be enrolled in Level I training to be completed in the first months of 2017. Level II courses will be available prior to the start of the National Matches. If you have questions about the RO Training Program, email the CMP Competition Department: competitions [at] thecmp.org.
Level I Range Officer Training
Level I Range Officer instruction covers general topics common to all Range Officer work. Enrollees will receive a Range Officer Handbook titled Becoming a Range Officer and be able to complete an online training course. Enrollees who complete Level I training will receive a certification and CMP Range Officer Vest and be eligible to attend Level II training.
Levels II and III Range Officer Training
Level II courses are discipline-specific, 1-day, in-person sessions taught by CMP-appointed instructors. Level II RO instruction will be offered for four shooting disciplines: 1) Highpower Rifle; 2) Bulls-Eye Pistol; 3) Rimfire Sporter; and 4) 3-Position Air Rifle. The highest Level III certification will be issued after Range Officers who complete Level II training serve as Range Officers in CMP competitions under the supervision of a CMP Master Range Officer. CMP Master Range Officers will conduct/supervise the training of Level II and Level III students. The first Level II courses should begin in March or April.
CMP Rimfire Sporter Competition Level II Training will be offered for this and other specific disciplines.

Boresighting the old-fashioned way — by looking down the bore of a rifle at a target — is not difficult. With a conventional bolt-action rifle, visual bore-sighting can be done quickly and easily: rest your gun securely on bags, remove your bolt and set up a 50-yard target with a large bright orange or black center circle. Look through the back of the action and you should be able to sight down the bore with your own eyes just fine. There’s no need for expensive hardware. In fact it may be easier to bore-sight the “old-fashioned way” rather than try to see a laser in bright sunlight at 50 yards (or even 25).
However, with lever guns and semi-auto rifles, including the popular AR15, M1 Garand, and M1A service rifles, the design of the receiver may make it virtually impossible to sight down the bore with the naked eye. That’s where a modern laser bore-sighting device comes in handy. For those situations where a bore-sighting tool is actually needed, we recommend a laser bore-sighter that fits inside your chamber. The in-chamber configuration is more fool-proof, and is inherently safer.
In-Chamber Laser Should Be Safer
Among the laser bore-sighters available on the market, we strongly favor those that fit in the chamber, rather than in the bore. With muzzle-entry laser bore-sighters, you could have a nasty accident if you forget to remove the device. There is always the chance you could chamber and fire a round with the muzzle-entry bore-sighter still in place. Instant Kaboom. That has happened more than once. With an in-chamber bore-sighter, there is no possibility you could chamber a loaded round with the bore-sighter in place. That’s an important safety advantage. Sightmark in-chamber bore-sights are shown in the video below. You can see that, with the bore-sighter in place, you cannot chamber a live round.
In-Chamber Bore-Sighters for Rifles Sightmark offers compact laser bore-sighters that fit inside your firearm’s chamber. The laser is housed in a brass assembly machined to duplicate a cartridge. These are easy to use — simply twist the end-cap to activate the laser, then place the bore-sighter in the rifle’s chamber. The affordable ($29.99 – $35.77) Sightmark boresighters are offered in a wide variety of pistol, shotgun, and rifle “chamberings”. Rifle options include: 17 HMR, .223 Rem, 22-250 30/30, .308 Win Family, .25-06/.270/.30-06, 6.5×55, .270/.300 WSM, .300 Win Mag, 50 BMG, and many other large hunting calibers. SEE Full Product Line.
Cabela’s also offers a Professional .223 Laser Chamber Boresighter that fits in a .223 Rem rifle chamber. This $59.99 unit, shown below, can be adapted to other chamberings by adding a caliber-specific sleeve over the .223 core unit.
Adapt Basic Unit to other Calibers with Sleeves
Cabela’s Professional .223 Laser Chamber Boresighter unit can be used for a variety of chamberings by fitting additional $19.99 caliber-specific sleeves (sold separately). Each sleeve is precision-machined from brass to SAAMI specs. One purchaser notes: “Extremely well made, the fit is so precise that I would recommend using a drop or two of light oil on the 223 laser insert before fitting it into the sleeve.” Available chamber sleeve calibers include:

TacticalWalls.com, producers of home security/concealment products, has introduced a new line of furniture with hidden gun storage. Tactical Walls’ new Coffee Table, End Table, and Night Stand provide “hidden in plain sight” solutions for defensive firearms. These tables all feature a clandestine metal gun compartment that can be instantly accessed via RFID card.
At first glance, the TacticalWalls tables appear to be nothing more than quality wood furniture pieces. (Each unit is made from hardwood and crafted in Shenandoah, Virginia.) But what’s special are the remote-activated hidden gun bays. By swiping a pre-programmed RFID card supplied with each unit, the hidden compartment underneath the table-top is unlocked, giving instant access to your handgun, shotgun, or rifle.
These products are nicely crafted, and RFID access is a smart use of modern technology. However, the TacticalWall tables are pretty expensive. The Coffee Table (49″L x 24″W x 19″H) costs $795.00! That will buy a pretty big gun safe. The two smaller units, the Night Table (above left, 23″L x 23″W x 31″H) and End Table (above right, 23″L x 23″W x 25″H) each cost $495.00. For that kind of money you have a variety of gun storage choices. Still, this could be a nice “instant access” bedroom option. You could keep your pistol right at your bedside, close at hand, but still completely secure.

A new .22 LR rimfire shooting discipline has been developed, copying the PRS series. Call it “PRS Lite” — a practical-style match shot with .22 LR bolt-action and self-loading rimfire rifles. This series will be called the Practical Rimfire Challenge (PRC) with ELEY as Title Sponsor. The first three matches will be held at the Peacemaker National Training Center in Glengary, West Virginia. Match Dates are March 25, May 13, and September 30, 2017.
PRC Matches Will Feature Multiple Positions and Movement
ELEY Practical Rimfire Challenge series matches are positional shooting events in field conditions out to 300 yards. You can use either a bolt-action or semi-auto .22 LR rimfire rifle. Much like PRS (Precision Rifle Series), competitors will shoot from a variety of positions: prone, strong/weak shoulders, standing, sitting, and kneeling. There will be shots from barricades, and movement from position to position during stages.
PRC rules will, to a large degree, mirror PRS rules. However, shooters will see some different type of stages than what is normally seen at a PRS match. For example, there may be unsupported standing or unsupported kneeling shots in some stages. Peacemaker’s goal, along with ELEY, is not to replicate PRS in Rimfire, but rather to create the ultimate challenge for shooters on the rimfire rifle platform.
Cole McCulloch, owner of Peacemaker, says that the PRC should appeal to a wide variety of shooters: “We expect to see recreational, action, Olympic, NRA and PRS shooters all competing and having fun”. McCulloch also expects rapid evolution in the equipment: “I fully anticipate a Space Race for this sport. Meaning, we already know that the ammunition coming out from ELEY is fully capable of hitting small targets out to 300 yards. What will be fun to watch is the different types of rifles and optics the shooters choose to use. Some examples of this will be: Bolt or semi, heavy or ultra-light weight, MILS or MOA, 10 power or 30 power. The debate will rage and the rifle platform approaches will vary greatly.”
Rimfire Tactical Matches Aren’t Really New
We’re pleased to see this new PRC shooting discipline — it sounds like fun. However, the concept of a rimfire tactical/practical match is not new — at least on the West Coast. California shooting clubs have been running “Rimfire Tactical” matches for a nearly a decade already. CLICK HERE to read our comprehensive Rimfire Tactical report from way back in 2008. This article includes free targets, ballistics charts, and a complete run-down on suitable rimfire rifles.
The Concept Behind the Rimfire Tactical Match by Bill Erwin
Many guys who shoot long-range tactical matches practice with .22 LR rifles of similar configuration. Rimfire ammo is way more affordable than centerfire, you do not need a big range facility, and shooting rimfire saves wear and tear on your centerfire rifle. Further, for learning how to read the wind, there really is no better training tool than a 22 LR, even as close as 50 yards. Check out this table showing how a .22 LR ballistics compare to .308 Win:
22 LR vs. .308, Distances for Equal 10 MPH Wind Drift
This table shows the corresponding distances at which a 10 mph full-value crosswind pushes a .22 LR bullet and .308 projectile the same amount. Values are based on 0.130 BC for a 40gr .22 LR bullet, and 0.496 BC for 175gr .308 bullet.
22 LR 40gr 1050 fps
50 yd Wind 1.0″
75 yd Wind 2.2″
100 yd Wind 3.8″
125 yd Wind 5.8″
150 yd Wind 8.2″
175 yd Wind 11.0″
200 yd Wind 14.3″
.308 Win 175gr 2650 fps
130 yd Wind 1.07″
180 yd Wind 2.15″
230 yd Wind 3.68″
280 yd Wind 5.63″
330 yd Wind 7.98″
380 yd Wind 10.71″
440 yd Wind 14.56″
This table shows how the .22 LR can be an effective substitute for a .308 Win during training. Because the smaller bullet drifts more in the wind, a 22 rimfire shooter will experience roughly the same crosswind effects as if he was shooting a 175gr .308 twice as far out. So, rimfire work can teach you to dope the wind like a .308, but at less than half the distance. Shooting a .22 LR at 100 yards is like shooting a .308 (with 175 SMK) at 230 yards.

While many folks enjoy the convenience of an electronic powder scale/dispenser such as the RCBS Chargemaster, some hand-loaders still prefer to use a traditional balance beam. Balance beam scales are simple, compact, and don’t suffer from electronic “glitches”. Moreover, even if you use a digital dispenser at home, when you’re doing load development at the range, a balance-beam scale may be more convenient. A scale doesn’t require electrical power, so you don’t need to bring battery packs or string long power cables. Just bring some kind of box to shelter your beam scale from the wind.
While designs like the RCBS 10-10 are decent performers as built, they can be made much more precise (and repeatable), by “tuning” of key parts. Forum member Scott Parker (aka SParker) optimizes a variety of popular beam scales, including the Ohaus 10-10 (USA-made model), RCBS 10-10 (USA-made model), RCBS 5-10, Lyman M5, Lyman D5, and others. You send Scott your scale, he tunes the key components, tests for precision and repeatability, and ships it back to you. The price is very affordable (under $85.00).
Scott tells us: “I have tuned several 10-10s. They all have turned out very sensitive, consistent and hold linearity like a dream. If only they came that way from the factory. The sensitivity after tuning is such that one kernel of powder registers a poise beam deflection. For repeatability, I remove the pan and replace it for the zero 10 times. The zero line and the poise beam balance line must coincide for each of those 10 tries. I then set the poises to read 250.0 grains. I remove and replace the pan 10 times with the calibration weight. For linearity, the poise beam balance line and the zero line should coincide within the line width. This is roughly one half a kernel of powder. For repeatability, the poise beam balance line must return to that same balance point ten times. I then adjust the poises back to zero and recheck the zero. I have a master’s degree in chemistry, thus I am very familiar with laboratory balances. Email me at vld223 [at] yahoo.com or give me a call at (661) 364-1199.”
The video above, created by British shooter Mark (aka 1967spud), shows a 10-10 beam scale that has been “tuned” by Scott Parker. In the video, you can see that the 10-10 scale is now sensitive to one (1) kernel of powder. Mark also demonstrates the’s scale’s repeatability by lifting and replacing a pan multiple times. You can contact Mark via his website, www.1967spud.com. To enquire about balance-beam scale tuning, call Scott Parker at (661) 364-1199, or send email to: vld223 [at] Yahoo.com.
