Here’s a valuable web resource our readers should bookmark for easy access in the future. ShootForum.com offers a vast Bullet Database, which includes over 3900 bullet designs in all. We counted nearly 200 different 6mm bullets! The bullet info comes from the makers of QuickLOAD Software. Access to the online database is FREE. Most database entries include Caliber, Manufacturer, Stated Bullet Weight, True Bullet Weight, Length, Sectional Density (SD), and Ballistic Coefficient. In many cases multiple BCs are provided for different velocity ranges.
The database is great if you’re looking for an unusual caliber, or you want a non-standard bullet diameter to fit a barrel that is tighter or looser than spec. You’ll find the popular jacketed bullets from major makers, plus solids, plated bullets, and even cast bullets. For those who don’t already own QuickLOAD software, this is a great resource, providing access to a wealth of bullet information.

Sierra has announced a new line of plastic-tipped MatchKing bullets. “Say What!? — that can’t be right…” you may be thinking. MatchKings have always been jacketed, hollowpoint bullets. Until now, plastic tips have been reserved for other Sierra projectiles, such as BlitzKing varmint bullets. But that is changing with the introduction of Sierra’s line of Tipped MatchKing (TMK) bullets featuring green acetal resin tips.
Plastic Tips Offer Better BC
Sierra says the plastic tips on TMKs enhance the Ballistic Coefficient (BC): “The major advantage of adding a tip to the bullet is the reduction of drag, producing a more favorable ballistic coefficient.” Stated BCs for the new TMK bullets are listed below. These BC numbers look good, and they have been verified with real-world testing: “We shot [all the new TMKs] multiple times (we actually test our BC numbers instead of letting a computer tell us what it is) and those numbers are all proven out!”
There will be six (6) new TMK bullets, two in .224 caliber, and four in .308 caliber. The six new tipped bullet types should be available in “early 2015″. Sorry, Sierra will not be offering 6mm, 6.5mm, or 7mm TMKs for the time being, although Sierra will introduce more TMK varieties in the future. Currently, Sierra is focusing on “the most popular calibers”. Notably, the new 22-Cal 77gr TMK has a 0.420 BC — identical to the BC of Sierra’s 80gr non-tipped HPBT MatchKing. So, you get the BC of a heavier bullet in a lighter projectile that can be pushed faster. That’s big news for .223 Rem and 22-250 shooters.
New Bullet Shapes Along with Plastic Tips
In addition to the bullet tip, some of these new TMK bullets have slightly modified shapes compared to previous-generation, non-tipped MatchKings (SMKs) of like caliber/weight. Sierra’s technicians reported: “The [plastic] point on the tip is smaller than the meplat on a SMK and if you look, you will also see the ogive on most of these [new TMKs] have been changed as well. Most of the big BC gains are from the reshaped ogives from the legacy SMK product.”

Quality .30-caliber bullets aren’t cheap. But here’s a deal that should make you take notice. Midsouth Shooters Supply has major-maker 175gr HPBT bullets in 500-count lots for just $99.01. That’s right, ninety-nine bucks for FIVE hundred 175-grainers from one of USA’s leading bullet makers. (Clever boys can probably figure out the source).
If you need match-grade .30-caliber bullets for your F-TR or tactical rifle, this is a very good deal — you’re effectively paying just $19.08 per hundred. We haven’t seen these kind of prices on .30-caliber bullets in a long time. If you’re interested, act soon — quantities are limited.
NOTE: These over-run bullets are also listed as OEM blem. That means there may be some cosmetic flaws, such as water spots or discoloration. But they should shoot fine.

If you shoot Service Rifle, or use a .223 Rem at medium to long range, you should read J. Guthrie’s ShootingTimes.com review of Black Hills MK 262 Mod 1 ammunition. Originally developed for military applications, this very accurate ammo is now available for civilians to purchase. It uses a special Sierra 77gr MatchKing bullet with cannelure. Black Hills did extensive testing to develop this ammunition, shooting over 250,000 test rounds with various propellants and projectiles. Eventually, the Sierra 77gr MK bullet was chosen, with a powder that delivers 2750 fps MV (from a 20″ barrel).
Sierra’s 77-grain bullet delivered great accuracy at long range. Guthrie explains: “Several bullets were used during the development process, including the 73-grain Berger, 77-grain Sierra MatchKing, and 77-grain Nosler HPBT. Black Hills finally settled on the MatchKing when Sierra agreed to put a cannelure on the bullet. In test fixtures Sierra’s bullet proved slightly more accurate. Accuracy was exceptional, certainly an improvement over M855 [military 5.56x45mm ammunition].”
Guthrie’s article explains that this ammo design started off as target ammunition developed for the USAMU. That was followed by a 1999 request from the Naval Surface Warfare Center, Crane Division for a round that would work with a suppressed, short-barrel M16 variant. Over the years, as Black Hills produced more ammo for the U.S. military, this ammunition continued to be improved. Guthrie notes: “The name changed with each modification. MK 262 Mod 0 was adopted in 2002, Mod 1 came along in 2003 with the cannelure, and an improvement to temperature sensitivity came along in 2005.”
According to Black Hills President James Hoffman, the MK 262 ammo “developed a cult following… so [in 2011] we started offering it to the public. The only difference is the packaging — it is the exact same ammunition as is delivered to the U.S. Military — loaded to the exact same specs”. The commercial version is sold in black/red 50-count boxes labeled “5.56mm 77 GR OTM”. The exact same ammo is issued to American war-fighters in 20-round, brown cardboard boxes labeled “5.56mm SPECIAL BALL, LR MK 262 MOD 1.”
Field Test of Black Hills MK 262 Mod 1 Ammunition
About J. Guthrie: Last April, at the much-too-young age of 37 years, outdoor writer J. Guthrie passed away in his sleep, leaving a wife and two young children. Field & Stream noted: “Guthrie was already a major player and a pro’s pro, but he wanted to be more. He wanted to be a Gun Writer in the old style. It’s a terrible loss for all of us that his run was cut so short.”

The 300 AAC Blackout (300 BLK, or 7.62x35mm) was created by Advanced Armament Corp. and Remington in order to provide the military with a way to shoot .30-caliber bullets from the M4 carbines with only a barrel change. It has since become popular with AR shooters for a wide range of uses including hunting and home defense. With the increased popularity of this cartridge, folks have been looking for reliable 300 BLK load information. Now, thanks to Sierra Bullets, we have some good load data for the 300 AAC Blackout. Sierra has released a FREE 6-page Load Guide for this cartridge, as part of the Sierra Reloading Manual (5th Edition).
Here is ONE of SIX Pages in the Sierra Load Sheet for 300 AAC Blackout
About the 300 AAC Blackout (300 BLK)
The 300 AAC Blackout cartridge shares case-head dimensions and body taper with the .223 Remington. Not only does this allow for compatibility with existing magazines and bolts, but it allows reloaders to form their own brass from cut-down 5.56×45 mm or .223 Rem cases. You can also form 300 Blackout cases by necking-up .221 Fireball brass. Take Note: Lapua has started producing .221 Fireball brass — this should be available in the USA by early April.
The 300 AAC Blackout is a similar concept to previous wildcats, such as the 30-221 and 300 Fireball, as well as the proprietary 300 Whisper®, except that 300 BLK was the first to be a SAAMI-approved cartridge and any company is free to make firearms or ammunition.
300 AAC Blackout is also finding use with hunters, who may not have been able to legally hunt with .223 in their state, and who prefer .30 caliber bullets for medium-sized game. It provides similar effectiveness to the 7.62×39 or the slightly more powerful .30-30 cartridges except works in the more up-to-date AR-platform rifles. Effective hunting range is about 150 yards. Some innovators, such as Dave Whitford, have also experimented with the 300 BLK for Across-the-Course competition. READ Whitford story in Rifleman’s Journal..

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.

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.

Prices of bullets and brass have gone up dramatically in recent months. We are hearing from active shooters that cost considerations are influencing their decisions about what calibers and chamberings to shoot. There is a definite trend to smaller cartridges and lighter bullets.
One match shooter told us: “I’ve been debating between a 6.5×47 Lapua and a 6-6.5×47. After comparing the cost of 6.5mm vs. 6mm bullets, I decided on the 6mm. If I save $7 bucks a box, and shoot 4000 rounds a year (40 boxes of bullets), that’s $280.00 in savings–enough to buy a new barrel.”
Here are some comparative bullet prices for 6mm, 6.5mm, 7mm, and 30-caliber bullets at Midsouth Shooters Supply. Prices are for a 100-count box. Note that the 6.5mm match bullets cost 25% more than the 6mms. For active shooters, the price difference adds up quickly. (Prices from current catalog listings; particular items may be out of stock.)

Consider Barrel Life Also
Certainly, moving to a smaller caliber can often reduce what you have to pay for brass and bullets. On the other hand, you need to consider barrel life. Hot-loaded 6mms, such as a .243 Ackley, can burn up a barrel much more quickly than a .308 Winchester. In comparing the “operating costs” of various cartridges, you need to factor in barrel replacement costs as well as component prices. If you have to spend $550 (including smithing) to replace a custom 6mm barrel every 1500 rounds, you’re spending $1100 more than a guy who has a .308 Win which lasts 4500 rounds.
