Since Sierra introduced the Tipped MatchKing® (TMK®) line of bullets in 2015, we have had a few questions from customers regarding the two lines of bullets (MK vs TMK). Some shooters are concerned that the tried-and-true MatchKing® bullets will be replaced with the Tipped MatchKing® bullets. For those of you worried, relax, the old standby MatchKings® that you have shot for years are here to stay, and we will happily continue to make them for you.

For those that like to try new products, we are planning on both continuing and expanding the Tipped MatchKing® line. Even where there are two bullets within these two lines that have matching weights (pictured above), 22 caliber 69 and 77 grain, 6mm 95 gr, 30 caliber 125, 155, 168 and 175 grains, we are not going to replace the MatchKings® with the Tipped MatchKing®. We are, however, going to continue to offer both lines of bullets for your use and enjoyment. Keep an eye out for new additions to our product line!

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.”

The GMX (Gilding Metal eXpanding) bullets are constructed of gilding metal, the same material used for bullet jackets. GMX bullets expand quickly and reliably upon impact, and retain nearly 100% of their weight. These GMX bullets contain no lead, making them a good choice for areas that restrict use of lead-cored bullets. To learn more, contact Black Hills Ammunition at (605) 348-5150.

New Black Hills 5.56 Ammo
For 2011, Black Hills is releasing two new 5.56mm offerings for commercial sale. First, it offers a new match load with 77gr Sierra MatchKings (SMKs). The new 5.56mm ammo pushes the 77gr SMKs at 2750 fps from a 20″ barrel. According to Black Hills: “this load delivers sub-minute accuracy consistently from 10-shot groups.”

Next, Black Hills is making its 50gr police 5.56mm load available to the public. The BHA 5.56mm 50gr TSX load was developed for U.S. law enforcement. This load utilizes a specially-built version of Barnes Bullet Company’s TSX bullet. It provides expansion to .50 caliber immediately upon impact and consistently penetrates to an ideal average penetration depth of 14″ in ballistic gelatin. Black Hills calls this “an ideal civilian defense or law enforcement patrol-rifle round” that works well through a variety of barrel lengths.
