SHOT Show: New 125gr Flat-Based .30-Cal MatchKing from Sierra

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.
