Sierra GameKing bullet (bottom) and MatchKing bullet (top). The MatchKing’s extremely small aperture stands in contrast to traditional hunting bullet designs that depend on large or skived openings or other enhancements to improve terminal performance. For those that like to try new products, we are planning on both continuing and expanding the Tipped MatchKing® line. Creedmoor General Manager Dennis DeMille, a past National Service Rifle Champion, states: “As a National Rifle Champion and having fired probably a Gazillion rounds down range (mostly hand loads), I would not hesitate to compete with this ammunition on a National Level!”.

Sierra MatchKing (SMK) vs. Sierra Tipped MatchKing (TMK) by Sierra Bullets Chief Ballistician Tommy Todd. First and foremost, the wind resistance is strong with these new projectiles.While 55 grain stuff is the flattest shooting inside of 600 yards, it gets bullied by the wind. The 1.355″ long bullet is advertised with a G1 ballistic coefficient of .518 at muzzle velocities above 2,200 feet/second. Both shot very well. We wouldn’t see these incremental changes in the performance of the AR platform if we didn’t push it to the edge of its capability. The civilian contractor took the ammunition out of its storage space, looked at the marking on the box stating “NOT FOR COMBAT USE” and refused to issue the ammunition to the sniper, instead instructing him to down load less-accurate linked M80 ball for use in his sniper rifle. Joined: Mar 14, 2015 Messages: 477. I also asked if there were plans to introduce a 6.5mm 130 grain MatchKing, to which Sierra responded, “not at this point in time, but our line is ever changing. The International Criminal Court limited the prohibition to military use of bullets designed to expand or open easily only when employed to “uselessly aggravate suffering or the wounding effect upon the target.”  In this respect the international community belatedly arrived at the point argued by Captain Crozier in 1899.

That gives you confidence that this ammo is consistent lot to lot. In 2006 a U.S. Army sniper approached his ammunition supply point in Iraq to request a re-supply of the M118LR. Today OTM ammunition is offered by a number of manufacturers for law enforcement and military use and has been adopted and employed by other militaries in the Afghanistan and Iraq conflicts. Potential functioning reliability issues, particularly in machine guns, discouraged interest in projectile design other than FMJ standard ball. _gaq.push(['_trackPageview']); This incident was avoidable. I am still tempted to try the 190s. 139 Posts . Nonetheless an important legal obligation was neglected by those who hesitated in requesting approval for combat use of the MatchKing, particularly given the significant increase in accuracy it manifested over the M118. })(); To comment on a post, click Post Title or "Comment" Link. When my 130 TMKs arrived, I immediately went to work developing some loads for my 6.5 Creedmoor. The addition of a ballistic tip to the product line increases the ballistic coefficient of both the 69 and 77 grain loadings and reduces the velocity drop off and increases wind resistance. 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. If i understand yoi correctly from above then you have a 1/4" jump to the lands. Good luck.

Sorry, your blog cannot share posts by email. 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; As described in this article, military interest in the MatchKing and other open tip match (OTM) bullets, including sniper use in combat, developed slowly due to misunderstandings that persist to this day. I understand H4350 is popular with the 6.5 Creedmoor, however, I’ve never really liked it in the cartridge. You may not reproduce original text or photos without advanced permission in writing. (function() { 6.5 Creedmoor load development: Sierra 130 grain Tipped MatchKing (TMK) with H4350, Varget, Reloder 15 and Reloader 17. Consult appropriate load manuals prior to developing your own handloads. Looking at my results thus far, I’ll be doing more work with Varget and Reloder 15. A common error is to look at the BC that Sierra gives for your MV and just use that. 44.5gr to 45.0gr is the correct charge weight range for Varget and 175 SMKs and long range. Confusion existed with respect to MatchKing use because different entities used the same words differently. I didn’t put enough orange dots on this target. In the late 1980s Naval Weapons Support Center Crane procured and tested 7.62 and .300 Winchester Magnum OTM ammunition with specially manufactured polished closed tips for possible sniper training and combat use, based on the belief that the OTM was prohibited for combat use because of its “hollow point.”  Although tests results were positive, Crane officials expressed concern that the projectile might violate the Hague Declaration because of bullet break up at close range, notwithstanding the fact that fragmentation of the polished closed tip M852 was no greater than U.S. military FMJ M80 Ball, and appreciably less than M80 Ball projectiles used by some NATO militaries. Sierra Bullets has remedied this somewhat by referring to it as “open tip match” in its invoices. If not i would seat them out farther and take advantage of more case space. Minimizing the meplat minimizes aerodynamic drag, preserving velocity, reducing time of flight, and providing a high quality flatter shooting bullet. Our 123 is one of our best sellers and suits a lot of uses for which the 142 is too heavy. Confusion bred by ignorance continues in some circles. ga.src = ('https:' == document.location.protocol ? Compare the above scenario with “normal” 77 grain SMK and the total flub factor is 33 yards where our mis-estimate can still score a hit. When I was at my first high power match, i saw a 60 year old man tear up the center X at 600 yards with his A2 service rifle and Irons. Using a Hornady OAL gauge, I measured the 6.5 Creedmoor with 130 TMK‘s to have an OAL of 2.866″ to the lands. many people fall back onto the “it is just a .22”. Past 100 yards I would probably take the opportunity to evade the danger, quietly if possible, than take a shot and give up my position. Precious few of us have access to anything past 300 and those are the lucky ones. I've used them quite a bit and I just load with same as I used for the SMK's. Many shooters are aware of the previous level of awesome unleashed on the 5.56 ballistics world known as the 77 grain SMK which is famously put together in the Black Hills Mk262 Mod 1 loading. In each case wound ballistics tests based upon Dr. Fackler’s protocol, today an integral part of the legal review of new military small arms ammunition, reconfirmed Dr. Fackler’s 1985 conclusion that the terminal ballistics of OTM projectiles are similar to those of FMJ Ball, that is, they do not “expand or open easily” in soft tissue. M852 use in DESERT STORM cannot be confirmed. Do you have room in the magazine for a longer overall length? An ally recently (and quickly) rejected a private citizen’s assertion that OTM ammunition violated the 1899 Hague Declaration.

This just means you’ll have to step out of your comfort zone and try different powders. According to Bryan’s measurements, here are some comparisons: Bryan provided this additional advice for users of Ballistics programs: “Sierra’s stated BCs are measured by live fire, and are typically pretty accurate if the velocity bands are properly observed (7mm being the exception). All shooting was done prone, from a bipod with rear bag. Some shooters are concerned that the tried-and-true MatchKing® bullets will be replaced with the Tipped MatchKing® bullets. Lack of military interest evolved into an assumption by many that military use of “hollow point” projectiles is prohibited in all circumstances, regardless of design intent and terminal ballistics. Below are Litz’s findings for four out of the six bullets he has able to acquire and test so far. I get the same velocity I was getting with the hp matchking 77`s. Work back up slowly and see if you find the higher node. 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). Would that time be better spend practicing? MatchKing Bullets: This is the classification for Sierra's pre-eminent target bullets. Dr. Fackler’s tests – firing the M852 into ordnance gelatin (20x25x50 centimeter blocks of a 10% weight concentration shot at four degrees centigrade calibrated to reproduce the crush and stretch seen in living animal tissue, a protocol developed by Dr. Fackler widely accepted today) – prompted him to suggest that the MatchKing’s terminal ballistics would be improved by expanding the aperture because M852 terminal ballistics were like those of 7.62mm FMJ M80 Ball.
