Subsonic testing part 2 -- Chronograph

Post by mr.revolverguy »

Part 1 viewtopic.php?f=141&t=97035

My obsession with the 300 Blackout continues and has lead to many fun hours on the range testing my reloads across the chronograph. The 300 Blackout is a great round for an avid reloader like myself, the versatility lends itself to easy reloading and can be used to reach it’s full potential. I have been on a mission to test the largest variety of bullets in my reloads and have also started to include factory ammunition in this testing as well. At some point I would like to evolve this testing into a form of cost effective penetration and bullet expansion test but ballistics gel is so expensive. If you have any good cost effective fun idea’s please share, let me know in the comments but I digress.

Before moving on to the next evolution of testing I have added the Digital Link Module to my Competition Electronics ProChornograph. I purchased it solely for the wireless capability to manage the chronograph from a distance.

At the bench I decided I would mate Reloader 7 with the Hornady 208gr A-Max, SierraProHunter 220gr, Sierra 220gr Match King, and a 203gr Palmetto lead coated bullet with hopes of achieving consistent subsonic loads that produced good accuracy. I used my normal reloading process and checked every round in my Sheridan Case Gauge a tool that has proved to be invaluable on my reloading bench.

Here are some of the amazing export capabilities from Digital Link, a plethora of useful data.

What is the range of the digital link?
Could you use it downrange to check the velocity at the target?

Great question something I will add to the review. I walked out 72Yards line of sight before I lost my connection. With a brand new battery in the unit and IPhone charged to 100%
