One in a row....

Everyone seems to have a Carnival of some kind, so I'm going to start my own: the Carnival of the Chronograph. I've got a bunch of chrono data laying around from my load development that might be helpful to others who don't have access to the same equipment, so over the next few days I'll be posting a whole lotta' data.

Data gathering method: Chronograph placed 10 feet in front of the firing line. Ten shot are fired, with the velocity recorded for each shot. Individual velocities are than entered into an Excel spreadsheet for calculation of average velocity, energy in foot pounds (based on the average velocity), standard deviation, and IPSC power factor. I do my testing in the summertime, so ambient temperatures range from 90 to 110 degrees F with humidity in the 10 to 15% range. Handgun shells are reloaded in mixed brand, range pick up brass. Rifle and shotgun loads are grouped by case manufacturer.

Warning: this information reflects performance in my guns and may not be safe in your guns. Buy a reloading manual and read it. Do not load from the data presented here.

Having said that, let's start with everybody's favorite: the .45 ACP
