Sniper Central Custom Remington 700 Tactical Rifle (SC2) Test Results Average Velocity Standard Deviation Extreme Spread Accuracy w/flyers Accuracy no flyers Best Group 2724 fps 11.93 36 1.744" 1.744" 1.242" For some reason the SC2 would not shoot this round at all. I thought it was the bullet, but it shot the corbon 139 just fine. Uses Remington brass Very good standard deviation and extreme spread Fairly hot load, should provide excellent long range ballistics A large lot of ammo was custom loaded for GA Precision, but continued availability is questionable. KMW Long Range Solutions Custom .260 Tactical Rifle Average Velocity Standard Deviation Extreme Spread Accuracy w/flyers Accuracy no flyers Best Group 2826 fps 20.19 64 .816" .816" .415" 4" longer barrel gains 102 fps over the SC2 22" Ammo shot much better out of the KMW than the SC2 At over 2800fps, the ballistics at 1000y is as good as the 300 Win Mag 190gr Match Very nice long range load NOTE: "Accuracy with flyers" includes the raw averages including groups where the shooter called a bad shot before rechecking the placement of that shot. The "average without flyers" is the average group size with those "flyer" groups not added in.
