Many precision-oriented shooters are discovering that the “middle ground” in cartridge size is optimal for the 100gr to 115gr match bullets. With a mid-sized cartridge, you can run these pills faster than a 6BR or Dasher, without giving up much, if any, accuracy to a 6BR or BR Improved. The most accurate 600-yard rifle at this Editor’s local club is a 6-6.5×47. It can shoot as tight as a 6BR past 300 yards, plus it offers better ballistics, pushing 105 Bergers at 3140 fps.
If you’re considering a mid-sized 6mm cartridge for your next rifle, you’re probably wondering WHICH mid-size 6mm cartridge is best. We are often asked “what’s the difference between the 6×47 Swiss Match, the 6XC, and the 6.5×47 Lapua necked down to 6mm?” All three cartridges have 30° shoulders and fit a .308-sized boltface. However, alone among the three, the 6mm-6.5×47 has a small primer pocket and small flash hole. The 6×47 Swiss Match (made by RUAG), and the 6XC (produced by Norma), have a large primer pocket and large flash hole, just like a .308 Winchester.
Forum member DesertLefty has provided a line-up photo, with 6mmBR and .260 Rem cases provided for comparison. As you can see, the three mid-sized cases (6x47SM, 6.5×47 Lapua, and 6XC) are very similar. The Swiss Match has the longest neck, while the 6XC enjoys the highest capacity. But performance is very similar among the three cartridges (with the 6.5×47 necked down to 6mm). The same powders, (particularly H4350, Reloder 17, and IMR 4007SSC) work well in the 6×47 SM, the 6XC, and the 6-6.5×47 Lapua. The parent 6.5×47 Lapua case is rated at 63090 psi, while the new CIP rating for the 6XC is 63844 psi (4400 BAR). Both the necked-down Lapua brass and the Norma-brand 6XC brass can hold stout loads. Though the 6mm-6.5×47 has slightly less powder capacity than the 6XC, max velocities with 105-108gr bullets are quite similar. However, you should not substitute loads from the 6XC directly to the 6mm-6.5×47 or vice-versa. Because of the different case capacities and primer sizes, you should work up loads separately for each cartridge.
Sierra Bullets rolled out few new products for SHOT Show 2012. The one new bullet is a .30-caliber flat-based bullet, the 125gr OTM (open-tip match HP) MatchKing, item #2121. This unique flat-based bullet was designed in conjunction with AAC (Advanced Armament Corporation) and Remington for the new .300 AAC Blackout (BLK) cartridge, a relatively small cartridge based on the .223 Rem necked up to .30 caliber. The bullet length is tailored to correctly fit and feed from AR-15 platform magazines. The relatively light weight of Sierra’s new 125gr MK allows it to reach fairly impressive velocities even with a modest powder charge. Of course it can also be used in subsonic mode, running at sub-Mach velocities. However, it is more typical for .300 BLK shooters to run a heavier bullet, such as the 240gr SMK, for subsonic applications (the heavier projectile delivers much more downrange energy at subsonic MVs).
The projectile’s Open Tip is pinched for greater uniformity in the same manner as Sierra’s Palma Competition bullets. The G1 BC is surprisingly high for a relatively short, flat-based bullet: 0.310 (below 1600 fps), 0.330 (1,600-2,000 fps), 0.338 (2000 – 2650 fps), and 0.349 (above 2650 fps). Though it will perform well at low velocities in the .300 BLK, this bullet can handle the higher velocities produced by common .30 cal mid-sized cartridges, such as the .30-30.
The new 125gr Matchking is now being loaded in factory ammo, including Remington’s Premier Match, which retails for $34.00 for a 20rd box. These 125gr bullets are available now from MidwayUSA for $34.99 per hundred.
We dropped by the Stiller Precision Firearms SHOT Show booth to see the latest product roll-out from Jerry Stiller and his crew. Jerry showed off some of his hot new action designs, including the long-awaited Copperhead rimfire benchrest action. Along with two rimfire actions, Jerry unveiled his hot-selling P1000 Benchrest Action, and his new TAC30 AW bottom metal system for Rem-clone actions.
The advanced Copperhead rimfire BR action, “in development” for years, is finally a reality. This is a pure benchrest-quality action, built from the ground up to deliver the smallest groups with today’s rimfire ammo. The Copperhead’s innovative design features DUAL firing pins at 6 and 12 o-clock. This serves to make rimfire ignition as consistent as possible. This action also has an Anschutz-style feed ramp to aid feeding of single-shot rounds. Being very complex to manufacture, the Copperhead commands a fairly high pricetag — roughly $1300.00. For those in the highly competitive rimfire benchrest game, who demand the very best rimfire receiver available, the high price is can be justified by the action’s superior performance. Prototypes have already earned top places ijn many notable rimfire BR matches.
Along with the Copperhead, Stiller Precision offers a nicely-detailed, smooth-running 40x clone rimfire action that will fit any stocks inletted for the Remington 40 Rimfire rifles. This 40X Rem clone action is in stock and available know for about $950.00.
Yet another unique action from Stiller Precision is the Tac-30 AW. This is a Rem-footprint action made as a purpose-built tactical rifle foundation. It has beefy #8 screws for scope base attachment along with the ability to add rail pins to a picatinny rail to reduce the possibly of any screw failures. Along with that, it is specifically made to work in concert with Stiller’s detachable magazine bottom metal and Accuracy International AW magazines. The entire action, bottom metal and magazine combination is available for about $1,100.00. The AW magazine is superior to the standard AICS mag; the AW design is easier to load, and it holds ten rounds in a more compact (shorter) box.
Last but not least, Stiller showed us a P1000 action which is becoming more popular in the long range benchrest realm and is available in standard and magnum bolt faces for short and long action calibers. This dual-port action is only available in a right-bolt, left-port, right eject configuration. It is also available in 2 diameters – 1.350” and 1.550” in case weight is an issue. Interestingly, the P1000 is made to work without the standard recoil lug as you can see it has recesses cut in the bottom that will act as a recoil lug surface. Similar to other Stiller’s actions, the P1000 has a small size (0.068″ diameter) firing pin for enchanced accuracy.
Stiller Precision is working hard to catch up on existing orders as well as continuing to develop innovative, state-of-the-art actions for discerning customers. Most of the actions on display at SHOT show are in stock and ready to ship. In addition, Stiller hopes to resume production of his popular Viper and Diamondback actions in just a few months. Jerry cautions “be patient” if you are looking for a drop-port or other classic benchrest not currently in inventory.

The Swedish company Norma is making a major push to expand sales in the North American market. As part of this effort it is re-packaging Norma cartridge brass in affordable, 25-count boxes labeled “Norma USA”. At the 2012 SHOT Show in Las Vegas, Norma USA will introduce a complete line of US, European, and Weatherby cartrige brass for the consumer market. The brass will be sold in 25-count consumer packs with new Norma USA branding and graphics. According to a Norma spokesman, “the idea behind the 25-count pack is to provide an affordable option. Folks can try the brass, see how good it is, and then buy larger quantities as needed.” Later, Norma plans to offer 100- or 250-count “Shooters Packs”.
Here’s the big news folks: Norma is finally getting its USA distribution system in order — at least that’s the plan. Norma USA will warehouse and fulfill all Norma products in all calibers by mid-February of 2012 with distribution through major US retailers. Hopefully this means product will be on the shelves and there won’t be long waits “for the boat to arrive”.
To support the Norma USA product line, a completely new, up-to-date Norma USA website will be launched mid-January 2012. In addition, the Norma USA product launch will be supported by an extensive advertising campaign in NRA publications. Norma reps will also attend the NRA Annual Meeting in St. Louis, Missouri, April 12 – 15, 2012. New loaded ammo offerings will be announced at the Annual Meeting. (Sorry, Norma won’t release any info on the new ammo at this time.)

Sale Tip by EdLongrange. We welcome reader submissions.
How would you like to be able to shoot a rimfire rifle or pistol that only makes 25% as much noise as a standard .22 LR gun? And no, we’re not talking about a suppressor-equipped firearm. CCI claims that its new Quiet-22 rimfire ammo “generates one-quarter the perceived noise level of standard velocity .22 LR rounds.” So this stuff is very quiet indeed, and it’s also affordable — a 50-round box sells for under $4.00 at major online vendors.
CCI’S 710 fps Quiet-22 Ammo only produces 68 Decibels (dB) of sound at the shooter’s ear (compared to 132-139 dB for a standard .22LR). How do we put that in perspective? Consider this: 68-70 dB is the noise level inside a typical family sedan cruising at 70 mph. For additional comparisons, a typical alarm clock ringer produces 80 dB of noise, while a hair dryer can deliver 90 dB. The sound levels at rock concerts can top 115 dB, and a chain saw can hit 125 dB.
To achieve its low sound levels, CCI’s Quiet-22 ammo sacrifices both speed and energy. Rated velocity is just 710 fps, and the 40gr LRN bullet only has about 36 ft-lbs of energy at 100 yards. So this ammo may not be a great choice for varminting, except for very small prey. On the other hand the ammo could be ideal for short-range plinking and fun shooting. For paper punching, CCI notes that Quiet-22 ammo offers better performance than an air rifle with similar noise levels. CCI’s Quiet-22 Ammo may also be perfect for areas where shooting is allowed, but noise pollution is a concern.
Do You Need To Wear Muffs?
CCI says you can shoot this ammo without hearing protection. The 68 dB report of this ammo is well below the 85 dB(A) noise level at which OSHA requires hearing protection in the workplace. However, remember that, when you’re at a range with other shooters, you must shield your ears from the noise produced by other firearms. So even if you use Quiet-22 ammo, you’ll need muffs/plugs if other shooters nearby are using conventional rimfire and centerfire ammo.
Following up on the success of its Zombie-Max ammunition, Hornady has introduced a new line of Z-Max Varmint Bullets fitted with “slime green”-colored plastic tips. What can we say — it’s a gimmick but it sells. P.T. Barnum would be proud. Hornady will initially offer seven (7) types of Z-Max bullets, in calibers .172 through 7.62 (.310), with weights from 20 grains to 123 grains.
Along with showcasing his books, match ammo, and other products, Bryan Litz’s Applied Ballistics website offers detailed Bullet Data Profiles for popular match projectiles. These profiles provide accurate bullet dimensions, stability factors (based on barrel twist rates), plus sophisticated multi-value BC tables that provide field-tested BCs across a wide velocity spectrum. Using these tables, you can select a G1 or G7 BC that closely matches a bullet’s actual muzzle velocity fired from your gun. Choosing the right BC for a bullet’s known MV from your rifle provides a more accurate ballistics solution — which translates to more first-round hits on the target.
New 6mm Bullet Data Profiles
Bryan recently added two new 6mm Bullet Profiles to his website: Sierra’s 107gr MatchKing, and Hornady’s 105gr A-Max.
Sierra 107gr MatchKing, HPBT
Sierra’s 107gr MatchKing has been used reliably in many medium- to high-capacity 6mm chamberings for many years. At 107 grains, this bullet is heavy enough to have a respectably-high BC while not being excessively long. This bullet is the ‘middle brother’ in the heavy end of Sierra’s 6mm target bullet line-up. The 95gr and the 115gr bullets have essentially the same nose and tail, and almost identical form factors as a result. The only difference being the weight which is taken up in the bearing surface. This bullet is comfortably stable in a 1:8″ twist in all but the worse case conditions, and even then the stability factor is still 1.33 which would result in acceptably accurate flight.
Hornady 105gr A-Max, PTBT
The 105gr Hornady A-Max is a very well-designed bullet with good performance. The plastic tip (PT) promotes a little higher and more consist BC compared to standard match bullet meplats while the 2.71-caliber long tangent ogive produces a low drag profile and good accuracy over a wide range of seating depths. The experimentally determined average G1 BC of 0.492 varies from 0.515 at 3000 fps down to 0.454 at 1500 fps. The G7 BC is a much better match for this bullet. Application-wise, this bullet was designed to be a match bullet, but has found favor with hunters as well due to the relatively thin forward jacket promoting good expansion.
Bryan’s Ballistics Book Offers Hundreds of Bullet Data Profiles
Bryan currently offers ten (10) detailed bullet profiles on his website — you can access these for free. If you want information on scores of other projectiles, you’ll find 236 other Bullet Data Profiles in Bryan’s definitive book, Applied Ballistics for Long-Range Shooting.
