Help with 50 BMG velocity

Use adjacent bench for LabRadar. Set to max offset in software. Ditch the tripod and use sandbags. Caldwell Tack Drivers stood on end with the LabRadar wedge between work great for high muzzle blast. External accelerometer trigger. Don't forget your external battery pack.

Edit: Bring the tripod. Always bring all the things when trying to get one shot sets of data. If you go the sandbag approach, tether the LabRadar so it doesn't fall off the bench when adjusting. Been a few years since I tested an M82a1 for a friend.
