One side of this gauge is the “go” side which quickly tells you the depth of a primer pocket, whether any crimp is properly removed, and whether the primer pocket is loose. If it feels loose on the “go” side, use the other end of the tool, the “no go” side, to test to see if the primer pocket is too loose to hold a primer. If the no-go slides into the pocket, then you know to junk that brass.
Primer Pocket Growth and Useful Case Life
Repeated firings at stout pressures can cause primer pockets to grow in diameter. This can create an unsafe condition if your primers are not seating properly. Are your primer pockets “good to go”, or have they been pushed to the point of no return? Do you really know? Many guys try to gauge primer pocket tightness by “feel”, as they seat the primer. But that method isn’t precise. Now there’s a better way…
The folks at Ballistictools.com have created a handy set of precision-machined gauges that let you quickly and accurately check your primer pockets. These gauges (aka “gages”) are offered in two sizes — for large and small primer pockets. A two-piece set of both large and small gauges costs just $25.99. These gauges let you quickly measure the depth of a primer pocket, and check if the crimp has been removed properly. Most importantly, the gauge tells you if the primer pocket has opened up too much. One side of the gauge has an enlarged diameter plug. If that “No-Go” side fits in the primer pocket, you should ditch the case — it’s toast.
Precision ground from O-1 tool steel, The Ballistic Tools primer pocket gauges serve multiple functions. The inventor of these tools explains: “I created the prototype of this tool for my own use in brass processing. I needed a way to quickly and easily measure primer pockets that was reliable and did not require wasting a primer. This tool has been indispensable for me and I would never go back to the old method of uncertainty and guessing.”

Progressive reloading presses offer shooters speed and efficiency in producing custom-tailored rifle and pistol ammunition. However, there is a wide choice of Progressive Presses and a bewildering array of options to consider. In this video, the 6.5 Guys and UltimateReloader.com’s Gavin Gear provide an overview of the leading Progressive Presses on the market along with key considerations for precision rifle shooters. If you are considering getting a Progressive for rifle ammo reloading, you should watch this informative, 25-minute video.
10 Tips for Reloading Rifle Ammo on a Progressive Press:
1. Make sure the brass is very clean. Don’t mix old range pick-up brass with newer brass.
2. Apply a thin, spray lube to all cases before the sizing/loading cycle.
3. Consider priming your brass separately (with a hand or bench tool) before the operation. Then inspect the primers before loading powder and bullets.
4. Always wear eye protection when loading with the Progressive, particularly if you are priming cases.
5. With masking tape, mark the powder measure/dropper with the powder type and cartridge charge weight. Check the charge mass multiple times (see below).
6. Cycle a few cases, sizing and adding powder but NOT seating bullets. Weigh the powder charges to ensure the powder measure is dispensing the correct charge. Sometimes this will change a couple tenths as it “settles down” after the first few charges.
7. Check the brass for shoulder bump and bullet seating depth carefully for the first few rounds, then check again periodically.
8. Try to maintain a steady pace and operate the handle the same way every time.
9. Visually inspect the powder charge in each case (before bullet seating), and use a lock-out die if your Progressive Press has enough stations.
10. Never, ever mix pistol and rifle powders! If you have previously loaded pistol ammo with your Progressive, make sure ALL the powder (every flake and kernel) is removed from all parts of the powder-dropping system before you add rifle powder.

If you are considering purchasing a progressive reloading press, definitely watch this 79-minute video covering a dozen presses from six leading manufacturers: Dillon, Frankford Arsenal, Hornady, Lee, Mark 7 (Lyman), and RCBS. Along with the big comparison video, Gavin Gear has prepared a detailed, 17-page online article which covers all of the presses in the shootout.
In this Ultimate Reloader Progressive Shootout video reviewer Gavin Gear demonstrates how each press works and provides data on costs, output rates, capabilities, and accessories.
Here is a cool video that shows the entire production process for a SilencerCo Octane pistol suppressor start to finish. Beginning with the raw materials, this video shows a wide variety of cutting, milling, drilling, burnishing, fitting, metal bathing, surface finishing, and laser etching processes.
If you have any interest in production methods you’ll want to watch this video all the way through, and maybe a second time.
SilencerCo states: “From cutting metal to chemical baths, to extensive quality control every step of the way, our streamlined process is more than just a few steps.” We think you may be surprised by how many steps are involved in producing this silencer (aka “suppressor”).
The Octane is a user-maintainable, multi-caliber centerfire pistol silencer featuring a modular mounting system for use across a wide range of hosts. High strength, stainless steel CTA™ (Click Together Assembly) baffles are easily disassembled for cleaning. This design makes the Octane one of the most durable small-caliber suppressors on the market.
In its Octane 45 review, SilencerShop notes: “When it comes to ease of maintenance, the Octane 45 is probably the simplest .45 suppressor on the market. It uses the new click-together baffle system from Silencerco/SWR – which allows the suppressor to come apart like a monocore suppressor, while providing performance that is closer to a K-Baffle design.””
NRA publication Shooting Sports USA (SSUSA) has thousands of articles online, all free for the reading. Many of these stories have been written by top competitors, including National and Olympic Champions. You will find SSUSA articles spotlighted every week on the NRA Competitive Shooting Facebook page. We recommend you bookmark that page as a valuable resource. Here are four notable SSUSA articles that have been featured on Facebook this month. Go to SSUSA.org to see even more current articles, with new content every day.
CLICK Above Image to READ Mirage Article
Here is an insightful, fairly lengthy 1850-word article about the phenomenon we call mirage. The article explains how and why mirage appears, how it can best be monitored, and how mirage can indicate both wind velocity and direction. Top competitors follow the adage “Mirage is your friend”, because mirage can often be the most important indicator of wind variables — sometimes even more important than wind flags. “The mirage is more sensitive than the flags since it has less inertia and momentum”, wrote Desmond T. Burke, in his book, Canadian Bisley Shooting, an Art and a Science.
Well worth reading, this SSUSA article talks about the properties of mirage. Here is a sample:
“Mirage — can make all the difference between a shot landing squarely in the X-ring or being victimized by an undetected downrange breeze. The true power of mirage is found in its ability to betray the subtlest of breezes downrange. Its fluid movement… can not only provide wind direction, but speed as well.
Typically, the ability to detect mirage is maximized on warm, sunny and sultry days. Expect mirage to be most pronounced in mid-morning or early afternoon, although it ignores these rules with regularity[.]
Mirage is extremely powerful at identifying winds of less than 12 mph, particularly those gentle breezes subtle enough to not even bother moving the flags.
When there is no wind, or a gentle head or tail wind, mirage will appear to be ‘bubbling’ directly up from the ground. Many call this ‘boiling’, and it is probably the easiest of all to detect.
As a general rule of thumb, when wind speed increases, overall height of the waves produced by the mirage is reduced. Large peaks and valleys in the waves mean that particular mirage is being driven by a very slight breeze. Conversely, crest size is reduced with wind speed, making it harder and harder to detect, until the mirage disappears entirely at somewhere around 12 miles per hour. In other words, the taller mirage’s waves appear, the slower the breeze.”

CLICK Above Image to READ Barrel Break-In Article
Authored by the late Glen Zediker, this article covers barrel break-in procedures. It is particularly useful for dealing with factory barrels. We CAUTION readers — with outstanding, hand-lapped custom barrels from top barrel-makers, you may want to do very little break-in — clean sparingly and keep barrel heat low. Do NOT use abrasives aggressively. On our Krieger and Brux barrels, we simply wet-patched every 2-3 rounds for 20 rounds and the barrels shot superbly from the start with minimal fouling. But for factory barrels, a moderate break-in process may prove beneficial.
Zediker explains: “Lesser, lower-cost barrels are going to have more pronounced … imperfections within the bore[.] These imperfections are largely tool marks resulting from the drilling and rifling processes. And if it’s a semi-automatic, like an AR-15, there might be a burr where the gas port was drilled. The goal of break-in is to knock down these imperfections, thereby smoothing the interior surface.”
CLICK Above Image to READ Case Failure Article
As one who has experienced a cartridge case-head blow-out with a 9mm pistol, this Editor is very conscious of the risks involved and the damage a blow-out can do to the pistol, to the magazine, and (worst of all) to the shooter. Even with new brass, the possibility of a case failure is always present. And even if the case remains intact, we’ve seen primer failures that create a dangerous jet back towards the pistol shooter. That’s why shooters should always employ protective eyewear whenever they shoot.
CLICK Above Image to READ Revolver Forcing Cone Article
We love our wheelguns, but there’s no doubt that forcing cone damage can occur, particularly with hot loads and if your cylinder-to-barrel gap is excessive. This article explains how to inspect your revolvers, and how to mitigate the likelihood of forcing cone damage. The article also explains how to clean your revolvers properly. This is very important to avoid build-up of lead and powder residues.
You can never be too safe when hand-loading your own ammunition. This article outlines the Seven Fundamental Reloading Safety Tips, as explained by Brownells. This is important information for novice hand-loaders and a good refresher for those with reloading experience! The Ulimate Reloader video below has some specific tips on loading hunting ammo, as it’s now hunting season throughout much of the nation.
Summary of the Seven Safety Tips:
1. Do NOT mix powders. Keep your powders clearly marked and dated. You can use masking tape to write the date on the container.
2. Check cases frequently. Look for split necks, case head separation or other signs of fatigue and excessive pressure.
3. Store your reloading supplies in a safe and dry location, away from children and away from any possible source of ignition. It is also smart to keep your powder and primers separate.
2. Get and use respected reloading manuals, especially for new cartridges. Start low and work up slowly while watching for warning signs of pressure and/or case fatigue.
5. Make sure you cannot be distracted when reloading. Turn off your phone. If you get interrupted, stop. (Distractions will eventually lead to mistakes.)
6. Make sure your ammo headspaces properly in each gun if you load the same cartridge type for different firearms. Even with the same cartridge, different guns may require different loads.
7. If reloading military brass, be aware that case capacity is usually reduced, and initial loads should be at least 10-15% lower than published data.
Here are some other tips that will help your avoid making costly mistakes (such as using the wrong powder, or undercharging a case):
Powder Type — Always double-check the label on your powder containers. After placing powder in the powder measure, put a piece of tape on the measure with the powder type written on it. Some guys write the powder type on a card and place that right in the hopper.
Scale Drift — Electronic balances can drift. If you are using a digital powder scale, calibrate the scale with a test weight every 50 rounds or so.
Case Fill — If you throw more than one charge at a time, look INSIDE every case before seating a bullet. Squib charges can be dangerous if you don’t notice them before firing the next round.
Progressive Presses — When using a progressive press, consider using an RCBS Lock-Out Die. This will detect a low charge and stop the machine. These dies will work with RCBS, Hornady, and Dillon progressives.
Conventional brass jags work great — except for one thing. They can react to solvents, leaving a blue “false positive” on patches. In recent years, jag-makers have experimented with many different materials in an effort to cure the solvent-reaction problem. Today we have polymer jags, nickel-plated jags, and stainless steel jags. And the latest innovation is the aluminum jag from Dewey.
J. Dewey Mfg. offers a series of “Copper Eliminator” jags and brush adapters made from aircraft-grade aluminum with the same hardness as brass. Dewey claims that its aluminum jags will not become embedded with grit or particles that could harm your bore. At the same time, Dewey’s aluminum jags will not react to ammoniated bore solvents that can turn patches blue green when used with brass jags. Dewey aluminum jags are offered with either male OR female 8/32 threads.
This coming Saturday, September 26th, is National Hunting and Fishing Day, held each year on the fourth Saturday of September. To help the avid hunters among our readers, here are Twenty Tips that can help ensure a safe and successful hunt. These tips have been compiled from our AccurateShooter Hunting Forum, with help from Hunting Editor Colton Reid (who has already been out hunting this month). Some items are preparatory — such as working with maps, sighting in the rifle, and improving physical fitness. We also talk about equipment — having the right gear, from proper boots to a GPS for multi-day hunts.
Of course there are entire volumes written on hunting, but these 20 Tips can benefit all hunters. Follow these suggestions and you should have a safer hunting experience with greater likelihood of success. If you liked these pointers, you’ll find two dozen more helpful hints on the NSSF Website.
Preparations Before The Hunt
1. Map Your Hunt and Notify Others — Before your hunt, make a plan and notify friends and family members about WHERE you are going and your intended return date and time. Print out a Google Satellite map and locate landmarks and trailheads. Mark where you plan to park your vehicle and give a copy of this map to friend and/or family members. A hunter may injure himself by falling off a rock, or tumbling in a creek-bed. After that kind of injury the hunter may be confused or unable to walk. If you get stranded in the wilderness, you want trusted persons to know where you are. So, before you leave on a trip, provide a map to a friend or family member. Show them where you will leave your vehicle, and where you expect to be every day of your hunting adventure.
2. Licenses and Permits — Make sure you have a valid hunting licenses and all the necessary tags. Begin this process with ample time before your intended hunt(s). The NSSF adds: “If you are crossing state or national borders, find out about any special considerations you must take care of. Border crossings can mean knowing about firearm transport laws or Chronic Wasting Disease-related regulations.”
3. Work on Your Fitness — On a multi-day hunt you may be trekking many miles. You need to be in good shape. If you are out of shape you may be putting yourself in a precarious situation, particularly if you underestimate the terrain difficulty. As the NSSF says: “Not being able to handle the conditions lessens your chances of success, can turn a great experience into an agonizing one and can endanger your health.”
4. Do Your Homework — Study the area you will be hunting. Talk to other hunters. Look at satellite photos. Get a real sense of the walking and terrain challenges. For a multi-day hunt, MAKE a PLAN. The NSSF states: “Eliminate surprises. Learn as much about where you will be staying, the area you will be hunting, what the weather might be like and what you need to bring[.]”
5. Rifle and Ammo — Make sure your rifle is sighted-in and your ammo is tested. Sight-in your rifle with the ammo you plan to use on your hunt. CLICK HERE for 4-Shot Sight-in Method. After sighting-in from the bench, confirm your zero by shooting from typical hunting positions (kneeling and with forearm supported on a rock or post).
6. Shooting Positions — Practice the shooting positions you will use in the field. Practice sitting, kneeling, and prone positions. You should also practice with shooting sticks, using your day pack as a rest, and with a bipod. Try to have a rock-steady rest before taking your shot.
7. Back-Up Irons — If possible, select a rifle with back-up iron sights. While modern scopes are very durable, they can and do fail (glass can crack). If you’ve invested a lot of time and money in your hunt, back-up iron sights can keep you in the game even if your riflescope fails.
8. Communications and GPS — Bring a GPS if you are in a wilderness area far from civilization. It’s a good idea to bring a cell phone, but you may not have coverage if you’re quite a distance from populated areas. A smart-phone also doubles as a digital camera to record your trophies. For navigation and safety, consider getting Garmin inReach Explorer+. This high-tech handheld unit features interactive SOS, connecting you to the GEOS 24/7 search-and-rescue monitoring center. They also allow you to send and receive text messages, no matter where you are, via advanced inReach satellite technology. Yes you can communicate even if you are miles from the nearest cell tower.
9. Select Good Gear — Make sure you have GOOD BOOTS that are comfortable — you’ll spend a lot of time on your feet. You may want a pack with harness for your rifle so you have both hands free. On a multi-day trip, make sure you can carry enough water, and that you will stay warm enough at night. Good practices for backpacking apply to multi-day hunts.
10. Make a Gear Checklist — Create a complete checklist of the gear and supplies you need. That includes arms, ammunition, rangefinder, binoculars, proper clothing (including spare clothes), hunting accessories, sleeping gear (on multi-day hunts), toiletries, medications. Don’t forget a good first aid kit — lots of bad things can happen during any wilderness trip. You can cut a hand, break an ankle or worse.
During The Hunt
11. Have a Plan — know where you plan to go and when. Try to be where you want in the early morning and early evening hours when deer are likely most active.
12. Take Your Time — If you spot a deer and get too excited and don’t take your time you may spook him. Go slow and glass. If possible, wait for the animals to bed down and relax. Then work out the best way to approach your prey. Remember, “You get so few opportunities, don’t screw it up!”
13. Glass More, Walk Less — Let your eyes do the walking — get good binoculars and use them. With their heightened senses of smell and hearing, deer/elk are able to spot you way better than you can spot them. If you are walking around a lot, chances are you are getting spotted by your prey.
14. Riflescopes Are Not Binoculars — Never use a riflescope as a substitute for binoculars. The temptation to do so is real, but when one does this, one is by definition pointing the muzzle of the gun at unknown targets. We like binoculars with built-in rangefinders. When glassing at long range, try supporting your binoculars on your pack.
15. Be Sure of Your Target before Shooting — Every year during whitetail season, farmers are forced to spray-paint their cattle or risk having them “harvested” by hunters who don’t bother confirming the species in their sights. Hunters with “buck fever” can make mistakes. When in doubt, don’t shoot.
16. Know When to Unload — When finished hunting, unload your firearm before returning to camp. You should also unload your gun before attempting to climb a steep bank or travel across slippery ground.
17. Bring Hearing Protection — While pursuing and stalking your prey you’ll want full sensory use of your ears. But when you’re finally ready to take the shot, slip in hearing protection. A shot from a large-caliber hunting rifle can exceed 170 decibels. Unprotected exposure to noise from a SINGLE 170+ dB shot can cause permanent hearing damage. (Source: ASHA.org). If you make a follow-up shot, you double that noise hazard. Therefore a hunter with a non-suppressed rifle should have hearing protection available.
You can keep a pair of easy-to-use quick-insert ear plugs on a cord around your neck. Or, get a lightweight neck band with earbuds, such as the Sellstrom Band, Peltor Band, or 3M Safety Band, all with a good 25 dB or better Noise Reduction Rating. You can keep these lightweight bands around your neck for quick deployment before you shoot.
“Once a hunter is successful, the REAL work begins.” — Colton Reid
18. Harvesting the Animal — When dressing your animal, be careful with the meat. You’ll want very sharp knives. Some hunters prefer knives with replaceable, razor-sharp blades. Don’t rush the task. Make sure you don’t get moisture or dirt on meat. The three spoilers of meat are heat, moisture, and dirt.
19. Pace Yourself When Packing Out — If you DO succeed, and bring down a big buck, will you be able to dress the animal and carry out the meat? Always be prepared to hike out with extra weight. If you are successful, make sure not to waste the meat you worked so hard for. Choose a pack that can help you carry a heavy load. Remember, this is not an insignificant challenge — you may be carrying 60 to 100 extra pounds in addition to your other gear. Again, take your time. Rest as needed. Don’t hurt yourself.
20. Remember to Enjoy the Experience — Our Hunting Editor, Colton Reid, offers this sage advice to all hunters, but particularly to novices: “Have fun, and appreciate your hunt, whether you bag a buck or not. It is a privilege to experience the wilderness and to get away from the city. Enjoy it while you’re out there. And keep your spirits up. You may get tired, but remember that ‘comes with the territory’. At the end of the day, yes you may be exhausted. And you may want to quit and go home. But stay positive, stay focused. Be patient, the experience is worth it.”

There’s a great online resource for hunters that will help you find game locations in your state and ensure you have all the proper permits and game tags. WheretoHunt.org features an interactive map of the country. For all 50 states, the NSSF has compiled information about hunting license and permits, where to hunt, hunter education classes, laws and regulations and more. For each state you’ll also find a link for required applications and license forms.
Wipe-Out brushless foam bore cleaner is a product we’ve used with great success on many rifles. With sufficient dwell time, it removes both carbon and copper fouling. You can combine it with Wipe-Out Accelerator or Patch-Out liquid to speed up cleaning time. Many shooters, including this editor, find that bore-brushing has been virtually eliminated with the regular use of Wipe-Out. (With some barrels however, you may still have to brush or use a bore paste if you notice stubborn carbon build-up in the throat area.)
CLICK HERE for full official instructions on use of Wipe-Out foam applied from the muzzle or the breech.
Method One: Apply Through Muzzle Our standard procedure with Wipe-Out is to insert an O-ring-sealed cleaning rod guide into the chamber and then squirt through the muzzle in short puffs. IMPORTANT: Put a towel or rag on the comb of your stock and watch for a little bit of foam to exit the rod guide. We usually wait 30 minutes for the bubbles to dissipate, then do a second foam application. Be sure to clean off any excess foam before it drips on your stock. It is important to keep the foam off fine wood or paint finishes.
Our actual routine normally starts with 3-4 wet patches with Carb-Out (to get the loose black stuff out), followed by the two foam cycles as explained above. Then we plug both ends of the barrel, drive home from the range and dry-patch out on arrival at the house. If the gun is going to be used again soon, that’s all we do. If there will be long-term storage we’ll run some Eezox down the bore.
Method Two: Apply Wipe-Out from Breech
You can also apply Wipe-Out from the breech. To allow breech-first application, Wipe-Out cans now come with a short plastic tube and a plastic tip that fits in your chamber. These can also be purchased separately for $2.50. However, we’ve found the plastic tip is too big for some chambers and it is not always easy to get a good, secure seal even if it does fit. Jason Baney has come up with a solution. READ Jason’s Wipe-Out Article.
Use Fitted Tubing for Breech-First Applications of Wipe-Out
You can apply Wipe-Out through the breech very effectively if you use fitted, plastic tubing. While this works well for bolt-actions, breech application is particularly handy for the Garand, M1A and other semi-autos. Jason Baney has written a short article describing this process. In a nutshell, you need one piece of tubing that fits the chamber tightly and then connects with a second, smaller diameter tube that attaches to the Wipe-Out can. This avoids any “over-spray” of foam in the action area, providing a clean, simple solution. Just squirt for a second or so, and wait for white foam to come out of the muzzle. Be sure to keep Wipe-Out off fine wood stocks.
Hunting season is starting soon in most states. For many, Fall hunting season involves liberating a rifle that sits in a safe most of the year, grabbing a box of cartridges, and heading to the wilds. But this “once a year thing” carries with it potential risks.
It is all to easy to grab some rounds that may look right, but which are, in fact, a slightly different chambering. Likewise it is possible some hunting rounds got put in the wrong box after last year’s hunting trip. Be very careful when you get ready for a hunting trip — check the headstamp, cartridge dimensions, and bullet diameter of all your rounds. If you make an ammo selection mistake, the consequences can be disasterous, as this story reveals.
The .223 WSSM and 6mmBR Disaster Report by Dr. Jim Clary
Under most circumstances, shooters don’t have to worry about chambering the wrong cartridge into the wrong rifle. After all, the cartridges are well marked and we all know which rifle we are shooting on any given day. In many cases, incorrect cartridges cannot be chambered — larger cases will not fit in smaller chambers, for example. No problem! That being said, I can tell you that even an experienced, careful and normally safe shooter can make a mistake.
The following is an account of just such a mistake that could have resulted in death or dismemberment. Fortunately, the shooter was not hurt, but the rifle was completely destroyed.
Last year, a friend purchased a Savage Precision right bolt, left port, single shot bolt action in 6mmBR Norma. It was an incredible prairie dog gun and he spent the summer burning powder and busting dogs. In October, he purchased a stainless steel Browning A-Bolt Varmint in .223 WSSM. The weather in the upper Midwest turned sour by the time he got the brass tuned up and he only got to fire it a few times before he was “socked in” for the winter. Thus, he spent his evenings loading ammo for the spring thaw.
During a break in the weather, he grabbed both rifles and a couple of bags of .223 WSSM and 6mmBR cartridges and headed to the range to check out his new loads. In case you are not familiar, the 6mmBR is smaller in diameter and a mite shorter than the .223 WSSM. Because of this, it will chamber in a .223 WSSM, but the .243 caliber (6mm) bullet is too big for the .22 caliber bore. That is what happened to my friend.
The rest is history — when he squeezed the trigger, all hell broke loose. The entire bottom of the rifle blew out, including the magazine assembly. The explosion actually cut the stock into two pieces. However, the bolt held and amazing as it may seem, the .243 bullet was “swaged” right out of the .223 barrel.
6mmBR (left) and .223 WSSM (right) cartridges above the remains of Browning A-Bolt rifle.
One Small Mistake Is All It Takes
Now, realize that my friend has been shooting all manner of firearms, safely, for over half a century. He is meticulous, thorough and conscientious in his approach to reloading and shooting. However, he made one mistake. He put some lose 6BR cartridges in a baggie as he packed up from a prairie dog hunt last summer, without noticing that the baggie was marked .223 WSSM in black marker. Then, when the break in his winter weather came, he grabbed the bag, believing it to be the WSSM cartridges and didn’t check the head stamp.
Couldn’t happen to you? How many times have we emptied our pockets of cartridges and dropped them into a plastic container on the shooting bench? How many times have we set down to a marathon reloading session, loading several calibers in a row? How many times have we put the wrong bullets, cases or primers into the incorrect container? My point is that even the safest of us can make a mistake. So, look at the picture above and take a bit more time when you reload your ammunition at home or chamber a round in the field. It might save your life.
Many short-range Benchresters have thought about converting their 6 PPC rig to shoot a 30BR for score matches, or a Dasher for mid-range (or even 1000-yard) games. That way you can have a rifle that does double (or triple) duty, giving you the most bang for your buck. Though an action with a PPC bolt won’t normally work with 30BR/6BR/Dasher cases with their larger .308-class rim (0.4728″ diameter), there is a pretty easy solution that allows you to cycle these bigger cartridges with a 6PPC-style bolt (designed to fit .220 Russian rims).
“Rebating case rims … lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle.” — Butch Lambert
Butch Lambert of ShadeTree Engineering provided this tip. Butch notes that many 6 PPC benchrest group shooters also enjoy shooting in score matches. But to be really competitive in the BR for score game, that means shooting a 30BR, which has a wider, .308-class rim (0.4728″ diameter). Likewise, if you want to compete in 600-yard registered BR events or in varmint matches, you probably want to run a bigger case, such as the 6BR, 6mm Dasher, or 6-6.5×47. Those cartridges also have the larger 0.4728″ rims.
Rebate Your 30 BR Rims
To convert a PPC-boltface action to shoot bigger cases you can spend a ton of money to buy a new bolt. That can cost hundreds of dollars. The simpler solution is to turn down the diameter of the larger cases on a lathe. Butch explains: “We’ve seen plenty of interest in rebating case rims. This lets you shoot a 30BR in score matches using your PPC action. All you need is a new barrel. This saves buying another bolt, receiver, or rifle if you have a PPC boltface. Anyone who has access to a lathe can do this job pretty easily. Yesterday I turned 150 case in about an hour.”
At right is the lathe form tool Butch uses to rebate the case rims.
The folks at Ballistictools.com have created a handy set of precision-machined gauges that let you quickly and accurately check your primer pockets. These gauges (aka “gages”) are offered in two sizes — for large and small primer pockets. A two-piece set of both large and small gauges costs just $25.99. These gauges let you quickly measure the depth of a primer pocket, and check if the crimp has been removed properly. Most importantly, the gauge tells you if the primer pocket has opened up too much. One side of the gauge has an enlarged diameter plug. If that “No-Go” side fits in the primer pocket, you should ditch the case — it’s toast.
Method Two: Apply Wipe-Out from Breech
Hunting season is starting soon in most states. For many, Fall hunting season involves liberating a rifle that sits in a safe most of the year, grabbing a box of cartridges, and heading to the wilds. But this “once a year thing” carries with it potential risks.
