Varmint Shooting with the 6mmAR ![]() Sample 6mmAR Varmint Upper with 24" Hart barrel, side charging handle option, and blue hand guard (black hand guard also available). While varmint loads testing has only recently been started, initial results clearly indicate the cartridge has exceptional varmint potential. Some chronograph results from January 14, 2007 indicate the following: 29 gr N133 with Hornady 75 gr V-Max - 3127 fps 29.5 gr. Benchmark with Hornady 75 gr V-Max - 3156 fps This was all shot with a 24" barreled 6mmAR upper that has a Hart 1:8" twist. All loads were using CCI BR-4 primers and the Hornady 75 gr V-Max bullet jumping .010" to the lands. There is clearly a number of powders that will undoubtedly work well in this application (Hodgdon's 4895, IMR 4895, VV N133, VV N135, VV N535, Hodgdon's Benchmark, Hodgdon's H322, along with a host of stick and ball powders too). NOTE: Don't rule out H335 as a powder - after this page was originally published, a number of varmint rifle shooters have reported great accuracy and velocity using H335 (and it throws within .1 of a grain out of most powder measures). One varmint hunter is running 80 gr varmint bullets around 3250 fps using H335 - that's smoking with a 6mm bullet of that weight out of an AR-15! ![]() The 6mmAR (center) vs a 223 (left) and a Hornady 75 gr.
