.308 and 7.62x51 Chrono Loads - Rock River Arms LAR-8 X1

Running two handloads - 150 grain Hornady FMJ BT, 165 grain SP Remington, plus two factory loads - Patriot Defense .308 and ZSR 7.62x51 M80 through my Rock River Arms X1 - specs here: https://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_ID=96.

Interesting findings, the handloads outshot and out performed the factory loads. These are low cost factory loads, so I didn't expect perfection. I was surprised at the low fps numbers. Temp was round 54-56 degree weather, altitude roughly 5500 feet above sea level.

Enjoying geeking out on the Chronograph and testing loads - I hope you enjoy the video!
