Every serious shooter needs to know the muzzle velocity (MV) for his load, so he can run ballistics solvers. And very consistent MV with low Extreme Spread (ES) and Standard Deviation SD is vital for consistent long-range shooting. You need good components and reloading techniques for low ES/SD. You want a good, reliable, and consistent chronograph to record your muzzle velocity — there are many good types now, including the compact Garmin Xero C1 and the handy Magnetospeed units which attach to your rifle.

Today we feature a new 55-minute video from Bryan Litz of Applied Ballistics. In this video Bryan explains how to measure muzzle velocity with various chronograph types and then explains some methods for optimizing your ES/SD. Bryan explains: “Muzzle velocity is an important variable for long range shooters. This video covers some key concepts for beginners and also goes into some advanced topics that are not normally encountered to keep it interesting for experienced shooters as well.”

This video from the manufacturer explains how to use the excellent Garmin Xero C1 radar chronograph. This popular new unit has proven to be user-friendly and very reliable. The ultra-compact size makes it easy to transport and deploy at the range.

Get a Good Ballistics App — Consider the NEW AB Quantum App

Once you have recorded your muzzle velocity successfully you can use the MV data with your known bullet BC and range altitude to plot the trajectory of bullet flight. This will tell you the correct scope elevation setting for the distance of your target. We recommend getting a good Ballistics App for your mobile device so you can run ballistics at the range.

Definitely check out the impressive new AB Quantum App from Applied Ballistics. Consumers can now download the AB Quantum App for either iOS (Apple) or Android devices.
