300 BLK OUT 10.5" vs 16" Velocity Data

[zimagold]

I collected some data on both 16" and 10.5" uppers and figured I would share the info.

10.5" - Aero Precision CM, 1:7 Twist, Pistol Gas

16.1" - Noveske CM, 1:7 Twist, Mid Length Gas

In general the velocity gain was about 125-140 fps with 125gr Nosler Ballistic Tips and H110.

All velocities were recorded using a Magneto Speed V3 at 72F at an indoor range. The testing was completed using 2003 production H110, I have added one point based on a 2014 lot of H110 for correction.

I chose not to include specific load data, but the testing was following the min and max loads listed in the Nosler Reloading Manual #7 which is available online.
