Seekins Precision SP10 Semi-Automatic Rifle 6mm Creedmoor 22" Barrel (1)-20Rd Magazine 10X Stock Battle Worn Olive Drab Green Cerakote Finish

Annnounced by Hornady in 2016, the 6mm Creedmoor was wildcatted by Outdoor Life's John Snow, the 6mm Creedmoor, as its name implies, is created by simply necking down the 6.5mm Creedmoor case to take a 6mm (.243-inch) bullet. Actual velocity is very similar to the long-popular .243 Winchester. The advantage is offers is that, with its shorter case, it does a bit better with the longer aerodynamic bullets that are winning matches--and that's its intent and primary niche, serious long-range competition with long, low-drag bullets that get past the finish line with very mild recoil. As a crossover varmint/deer cartridge it offers no real advantage over the tried-and-true .243, but it's just as good in those roles, and in the right hands (and the right barrels) might win a few more matches. — Craig Boddington
