To be clear, I DID NOT shoot my chronograph. Instead, I got my brother to do it for me. Mission for the day was to gather chrony data for his .500 Smith and .45-70 handloads, while I zeroed the Aimpoint on my AK in the next lane over. As will be seen, he only completed part of the first half of the mission before fatally injuring the Chrony of Truth with a single 440 grain hard cast bullet, after about a dozen rounds of incrementally more powerful loads through the .500 Smith hand cannon. In hindsight, it's maybe a little surprising that it took that many rounds for this to happen, and we should probably work on a better rest for future handgun chronograph efforts than just a couple of sandbags. Definitely if we are going to be using the Revolving Flinch Generator instead of a more normal handgun.
Chrony of Truth, RIP (rest in pieces). It served me well and truly and honorably in the time that I had it. Please note for the record, that it looks nothing at all like a bear, nor was it charging at the time of its death, despite the .500 hole blown through it.
AlaskaTRX poses with his handiwork.
