Better than you think - SIG SAUER SBR Solid Copper .300 AAC Blackout 120 Grain Hunting Tipped Brass Cased Centerfire Rifle Ammunition

I've tested this in and 8" and 10.5" upper. Accuracy was superb with both uppers coming in with under 1" @ 50yds both using RD sights. Velocities were surprising in both uppers breaking 2K fps with the 10.5 touching 2100 fps. That is just shy of Barnes 120 gr full up loads. Combine that with very clean burning powders, flash suppressed and impressive bullet performance this load is nearly ideal for under 150 yd shooting on mid sized game or as a defensive round.
