Want smoother chamfers on your case-mouths? Here’s a simple tip that can: 1) remove the sharp edge left by chamfering blades; and, 2) create a smoother entry for your bullets. Smoothing the inside chamfer can avoid nicks on your bullet jackets, and can also make bullet seating more consistent.
If you are using a 45° rocket tool on newly-trimmed brass, start your inside chamfer with two or three turns in the normal cutting direction. Keep the tool centered, and use light-to-moderate pressure — you don’t need to remove a lot of brass. After your cutting turns (which should reveal a shiny chamfer line), take out the tool, inspect the neck and remove any small brass chips or shavings.
Now here’s the secret — put your tool back in the neck and go in the reverse direction for a couple partial turns. Again, be sure to keep the tool centered and use a light touch. The reverse rotation of the rocket tool inside the case mouth will burnish and smooth the chamfer. Next you can make a quick spin with some fine steel wool held in your fingers. Don’t grind away — you do NOT want to get rid of all the carbon in the neck. As a last step we run a hand-held nylon brush in the neck for 2-3 quick passes to further smooth out the chamfer and remove any residue from the steel wool.
We think, if you use this procedure, your will find that your bullets seat more smoothly and consistently. That can improve accuracy and help avoid mysterious fliers.
You can use this same technique even if you prefer a sharper angle chamfer tool for your initial inside-neck chamfering operation. Reverse your tool gently a couple turns to burnish and smooth the cut. And always remove brass chips and shavings before you run the tool backwards (in the non-cutting direction).
Don’t Forget to Smooth the Outside Chamfer Too
You can also use the backwards rotation trick on outside chamfers to smooth and soften the sharp edge. A little steel wool, applied judiciously, can help here. If you are chamfering a large number of cases after trimming, you may want to tumble the brass in corn-cob or walnut media after the chamfering procedure. Tumbling further smooths the chamfer. You want a nice, smooth chamfer with no burrs or sharp edges.

Well it looks like there’s some real talent in the next generation of IBS Benchrest shooters. Watch out for those young guns — they can give seasoned veterans a run for their money — and then some. Young Kevin Donalds Jr. fired a perfect 250-25X score to win a 100-yard IBS score match at the Thurmont, Maryland range on May 18th, 2013. At just 12 years of age, Kevin is already showing he has the focus, talent, and determination to win. And, yes he managed to beat his proud father Kevin Donalds (Sr.) who finished second with a 250-23x. Like father, like son. It’s great to see a father and son who shoot together — and share the podium together.
Above, 12-year-old Kevin, match winner, is shown flanked on his left by his father (second place), and on his right by third place finisher Larry Fritz. Young Kevin was shooting a 30BR (no surprise), with a BAT action, Krieger barrel, and an affordable Sightron 8-32X scope (about $860). The rifle was smithed by Sid Goodling and stocked by Roy Hunter. The load was a stout charge of Hodgdon H4198, fired by Federal primers, pushing BIB 112gr bullets.
How would you like to lower your Extreme Spread (ES) and Standard Deviation (SD) significantly by a simple procedure that takes seconds and costs almost nothing?
Here’s all you need to do. After lubing your cases for full-length sizing, be sure to clean your hands (removing ALL residual lube) before you handle your bullets. As an extra measure to avoid lube contamination, slip on thin Latex gloves before you handle and seat your bullets. Will this make a difference? Let me tell you a story.
Keep Those Greasy Fingers Off Your Bullets
I recently loaded a couple dozen cases for a 6mm Dasher. We were in a hurry to leave for the range so I was loading faster than normal. When we started shooting the ammo I noticed that the 5-shot ES was bad — really bad — 48 fps. I was shocked because this was a known good load that had previously showed ES in the teens. This one had me stumped. What could have resulted in this high ES? What did I do different while reloading this time?
Then a lightbulb went off. I realized I had been seating bullets (round by round) immediately after lubing and sizing each case. My fingers still had some greasy lube on them which obviously got on some of the bullets, “polluting” them. My normal reloading procedure is to lube and size all cases, clean them off, then place the brass in a loading tray. Then I would clean my hands BEFORE adding powder and seating bullets. This time, in my rush, I sized a case, wiped it off, then immediately added powder and projectile. I did not take the time to clean off my fingers carefully before handling the bullets.
Big Drop in ES When I Avoided Bullet Contamination with Case Lube
The next day I went back to the loading room. I loaded the same brass with the same powder, same primer, same bullet type, same bushing — same everything. But this time, I washed my hands thoroughly with a hand cleaner, dried them with a clean paper towel, and I even put on thin latex gloves before handling the bullets. I loaded 10 rounds and fired them over the chronograph again in the same rifle. The 5-shot ES was 14 fps and the 10-shot ES was 22 fps (That’s normal for this load/rifle). Compare that to a 5-shot ES of 48 the day before. I had reduced my 5-shot ES by 70%! We were back in business. (By the way, the groups were also very small).
Lesson Learned — Keep Case Lube Off Your Bullets Your results may vary of course, but now I always make sure to remove ALL residual lube from my fingers before handling bullets or doing anything that can get unwanted lube inside the necks.
What about gloves? I don’t think the Latex gloves are essential (if your hands are dry and clean), but they just cost a few pennies when bought in bulk. You can buy a box of 100 latex gloves for under $7.00 on Amazon.com. I suggest the non-powdered type.
Use Your Common Sense
Before the critics launch a tirade, let me be the first to acknowledge that many champions have loaded perfectly good ammo (and shot great groups) without paying much attention to greasy fingers. We’ve all seen short-range benchresters loading ammo between relays. They work fast and may not take the time to clean all lube off their fingers before seating bullets. And we’ve seen some of those guys go out and shoot itty-bitty groups in the ones and zeros. So I am NOT claiming that careful “reloading bench hygiene” is essential to shooting small!
All I am saying is that I observed and recorded a significant drop in my ES when I made sure to avoid contaminating bullet jackets with case lube. This is a simple precaution that is easy to follow when loading at home. It may help you cut your ES/SD. It may help avoid that one “mystery flyer” that ruins a group. Cleaning your hands before seating bullets may seem obsessive. But the smart reloader knows that paying attention to the small details, in all respects, is the key to making ultra-accurate ammo that exhibits low ES/SD on the chronograph.
Shooting a 50 BMG, off-hand, at 1000 yards may seem absolutely nuts, but read on — this story should make you smile. At the Texas Triggers Ranch (Sonora, TX), former Army Ranger and Sniper Team Leader Ryan Cleckner, shooting OFF-HAND, hit a torso-sized steel silhouette target at 1000 yards with a 50-caliber Barrett M107. That would be impressive enough, but consider this — Ryan hit the target on his first shot. And yes he was shooting standing (on his hind legs), holding the 37-pound rifle with his arms (no support).

Jumbo-Sized Ammo, and Jumbo-Sized Recoil
The ammo Ryan used in his 50 BMG Barrett pushes a 661-grain bullet at 2900 fps muzzle velocity. This load (fired from this 37-pound rifle), has 12,357 ft-lbs of energy at the muzzle, and 81.88 ft-lbs of recoil energy. To put things in perspective, an 18-pound, .308 Win F-TR rifle, shooting a 168gr bullet at 2750 fps, has 7.99 ft-lbs of recoil energy. So, Ryan was shouldering a weapon that delivered more than Ten Times the recoil energy of a .308 Win. (Energy numbers calculated with Point Blank software). And he made it look easy. Kudos to Ryan for proving what a properly-trained marksman can do. Rangers Lead the Way….

For those of use who have sweated through fire-forming and load development, it’s nice to see things coming together right out of the gate. With the 6mmBR improved wildcats such as the BRX, BRDX, and Dasher, it’s not unusual to see outstanding accuracy even while blowing out cases. In fact the accuracy is usually good enough that you might as well do your fire-forming during competition (once you’ve confirmed that everything is working with a 10-round function test). We’ve seen Dashers shoot in the low twos and even ones during fire-forming — so long as you load carefully and use good bullets, powder, and primers. Here’s a report from Forum member Chris W. (aka “baydawg”) on his new 6mm BRX tube gun:
Shot my 6 BRX last night for the first time at 600 yards last night. The result was a 199-11X. Not bad for fire-forming brass with thrown loads… LOL. Thanks Gary Eliseo and Competition Machine for a kick-ass chassis!”
Gun Specs: Competition Machine R1 in Granny Smith green. Pierce repeater tube gun action. 32″ Bartlien 6mm barrel, chambered in 6mm BRX. Smithed by Pierce Engineering in Lansing, Michigan.
Hornady has received an inaugural Gold Predator Xtreme Readers’ Choice Award for its Superformance® Varmint™ 17 Hornet Rifle Ammunition. The 17 Hornet is currently available in 15.5gr NTX® and 20gr V-MAX™ offerings.
Hornady’s 17 Hornet employs Hornady Superformance® propellant technology. Hornady claims that, in the 17 Hornet, its Superformance powders can deliver 100 to 200 fps more velocity than other commercially-available propellants. As a result, Hornady’s Superformance® Varmint™ ammunition shoots flatter, drifts less in the wind, and retains more energy out to a practical range of 300 yards. And many varminters have praised Hornady’s low-recoil 17 Hornet, saying this new cartridge is economical, accurate, and fun to shoot. 17 Hornet ballistics are far superior to the 17 HMR, as you can see:
Hornady’s 17 Hornet was derived from the 22 Hornet parent case. Claimed velocity with 20-grainers is 3650 fps — an impressive number considering the 17 Hornet uses about half the powder of the 17 Remington. The 17 Hornet is based on the rimmed .22 Hornet case. However, the case is not just necked-down from .22 caliber. The case designers reduced body taper, moved the shoulder, and changed the shoulder angle to 25°. This effectively modernizes the old .22 Hornet case, improving efficiency while retaining the max OAL, so that the 17 Hornet can work in any action big enough for the .22 Hornet.
Predator Xtreme Readers’ Choice Award
The Predator Xtreme Readers’ Choice Awards, sponsored by Predator Xtreme magazine, honors the best new products for varminters and predator hunters. A Gold award is the highest honor bestowed in a number of shooting categories. Products are chosen for award recognition based on surveys of magazine readers, so this is truly an “people’s award”.
The 6mm Dasher is based on the 6mm BR cartridge with the shoulder blown forward about 0.100″ and “improved” to 40°. Case capacity is raised to about 41.0 grains. This allows the Dasher to drive 105-108gr bullets comfortably at 2970-3000 fps without over-stressing the brass. A popular load used by many successful Dasher shooters is 32.5 to 33.0 grains of Reloder 15, CCI 450 primers, with 105gr Berger VLDs, .010″ in the lands, or Berger 105gr Hybrids .015-.020″ off the lands (jumping). At the upper end this is a “warm load” and should only be used with fire-formed brass. Norma 203B is very, very similar to Reloder 15, and may be more readily available in the near future. As with any load, start 10% low and work up.
You may also have good luck with Hodgon Varget powder. Forum Member Rodney Wagner recently shot a spectacular IBS-record-setting 0.349″ five-shot group at 600 yards. Rodney was loading 32.5 Grains of Varget with CCI 450 primers and Berger 108gr BTs seated about .020″ off the lands (jumping). In preparation for fire-forming his Dasher cases, Rodney used a .257 expander to create a false shoulder on his case necks. This helps stabilizes the case with a good “crush fit” when fire-forming, but other methods of forming Dasher cases (including hydro-forming) can work well also.
Robert Hoppe, one of the top 600-yard shooters in the country, was the 2009 NBRSA 600-yard champion. In 2007, shooting a 6 Dasher, Robert nailed a 0.5823″, 5-shot group. At the time it was the smallest group ever shot in 600-yard registered benchrest competition. In 2008, John Lewis shot even smaller with an IBS Heavy Gun, but Robert’s 0.5823″ still remains the NBRSA 600-yard record, and we believe it is the second smallest group ever shot at 600 yards (in registered BR competition) by a 17-lb class rifle. Robert has been very successful in the 600-yard game, and is one of the best 600-yard shooters in the West. He knows how to wring the best accuracy out of the 6mm Dasher cartridge. Here Robert offers some tips on load development and tuning for the 6mm Dasher.
Our IT guy, Jay (aka JayChris in the Forum), was having some issues with his .260 AI. A load with known accuracy had suddenly and mysteriously stopped shooting well. Jay couldn’t figure out what was going wrong. Then he remembered he had cleaned his brass using a powerful ultrasonic machine.
He inspected his brass carefully and saw that the ultrasonically-cleaned necks were so “squeaky clean” that he was actually scratching the jackets on his bullets when seating them. As well, Jay noticed that it took more force to seat the bullets and the seating force became less uniform case to case. Jay solved the problem by applying NECO Moly dry-lube inside the necks of his brass before seating the bullets.
The Perils of Ultrasonic Brass Cleaning by JayChris
I rotate my brass so that I can keep track of each firing, so I keep a “clean/ready to load” bin and a “fired” bin. I have 400 pieces of .260 AI brass. So, all of it was on its first firing (after doing a Cream of Wheat fire-forming) until I hit the 400-round mark. To my surprise, things went south at the 500-round mark. The first time I noticed it (according to my range log) was at a match last year, when I dropped several points and had some vertical stringing issues. After that match, I had 400 rounds through the barrel and all of my brass had a single firing on it. So, it was time to clean.
I have used an ultrasonic cleaner for a while now. I recently got a more powerful Ultrasonic cleaner, although I don’t know if that makes a difference. My brass comes out dry and squeaky. Emphasis on the “squeaky”.
I found that my new US machine may have been getting the necks TOO clean. After ultrasonically cleaning my brass, I had noticed that it required a little more force to seat the bullets, but I didn’t really think too much about it. But then, after going over my ordeal with a shooting buddy and going over my process in minutiae, we had an “AH HA” moment when it came to cleaning (he uses good ol’ vibratory cleaning).
So, I used some moly dry-lube to pre-lube the case necks and took some rounds out to test at 200 yards. I used my last known good load and sure enough, the vertical flyers disappeared! I shot two, 10-rounds groups with .335 and .353 MOA vertical dispersion, which is consistent with the results I was originally getting.
Other folks have suggested necks may get “too clean” after ultrasonic cleaning. It was pretty sobering to actually witness, first hand, what can happen when brass is “too clean”. I had read some discussions of issues with neck friction/bullet seating after ultrasonic cleaning, but, frankly, I dismissed the idea. Now I understand. The “too clean” effect doesn’t seem to affect my Dasher at all (perhaps because Dasher necks are very short), but on the bigger .260 AI, it definitely does.
Close-Up Photos of Case-Necks
Here are photos Jay took with a microscope. You can see the difference between tumbled brass and ultrasonically-cleaned brass. Jay says: “Here, in sequence, are the Ultrasound-squeaky-clean case neck, a case neck after treatment with NECO moly dry-lube (you can see the particles that will help coat the neck during seating), and, finally, the neck from a case cleaned with corncob media in a vibratory tumbler. You can clearly see how much smoother the inside of the tumbled neck is. Yes, it’s dirty, but it’s also very, very smooth.
Close-Up of Scratched Bullet
Here is a close-up of a bullet that was seated in an ultrasonically-cleaned (“squeaky clean”) neck, with no lubrication. You can clearly see the damage done to the jacket — in fact, in a couple spots you can see the lead core through the scratches! Jay also observed that quite a bit more seating force was required to seat the bullet in a “squeaky clean” neck.
NOTE: The bullet jacket is naked — NOT coated in any way. It looks a little dark because of the shadow from the microscope lens, and the high contrast.
We often get questions about the 6.5 Creedmoor Cartridge — folks ask where they can find good resources for this cartridge, which is popular with Across-The-Course, High Power, and tactical shooters. We did some searching and found that the August 2011 digital edition of Shooting Sports USA has a good article for all fans of the 6.5 Creemoor.
Development of the 6.5 Creedmoor Cartridge
In the August 2011 Edition of Shooting Sports USA you’ll find a lengthy feature on the 6.5 Creedmoor cartridge. This story covers the origin of the cartridge and its performance both as a match cartridge and as a hunting round. Hornady Chief Ballistician Dave Emary explained: “the original intent of the cartridge was as an across-the-course match cartridge. We envisioned it as an off-the-shelf round that would produced the accuracy and ballistics to compete in all match disciplines right out of the box. At the same time we realized that the same characteristics would make an exceptional hunting cartridge with the right bullets.”
6.5 Creedmoor Brass No Longer Washed After Annealing
Here’s an interesting update on Hornady 6.5 Creedmoor brass and loaded ammo. In a move to improve case quality and neck uniformity, Hornady recently changed the 6.5 Creedmoor production process, eliminating the case-washing step after annealing. So now you will see annealing coloration on 6.5 Creedmoor brass, just like on Lapua brass. Dennis DeMille of Creedmoor Sports wanted to improve the consistency/uniformity of 6.5 Creedmoor case-necks. At Dennis’ suggestion, Hornady conducted tests which showed that the “standard industry practice” of washing brass could potentially alter the necks in undesirable ways. Bottom line, unwashed annealed brass was determined to have an accuracy edge over washed brass. Looking at these results, Hornady decided to forgo the post-anneal washing process. As a result, the latest 6.5 Creedmoor brass now displays the distinctive coloration left by neck/shoulder annealing. Learn something new every day, eh?
You can use this same technique even if you prefer a sharper angle chamfer tool for your initial inside-neck chamfering operation. Reverse your tool gently a couple turns to burnish and smooth the cut. And always remove brass chips and shavings before you run the tool backwards (in the non-cutting direction).
