Stats to take from Chrono?

[CALI SHOT DOC]

I got a Chrono for xmas and am going to go out in a couple days and use it for the first time. I was wondering what I should take away from it other than velocity/power factor. Contemplating using excel or just keeping a journal for the info i get from it.

I'd appreciate any tips/suggestions

Thanks Guys

If you are a reloader you can use it to see how your loadups vary with different assemblies IE: Projectile, powder brand/grain amount etc.. You can plug the average FPS into the elevation formula for your particular weight and velocity of the projectile for easier targeting at distance. Standard rounds say .243 its always good to know your velocity from store bought/off the shelf ammo if you are doing anything past 100m for the bullet drop as well.

I use mine for these reasons and its very helpful for my 800m shots with prarie dogs or to know if i accidently loaded a round too hot (almost never happens).

when you get the FPS, just add that to your records for your recipe. Maybe add the variance (+ or - 100FPS, or whatever it works out to). FPS and bullet weight will give you your power factor, so that can be determined any time later.

I'd love to use a chrono to dial in my recipes, but I don't know if i'll want to permanently own one. (obviously if I'm constantly experimenting or designing new recipes i'd need one.)

If you are a long range shooter or shooting for the best accuracy then knowing your Extreme Spread and Standard Deviation in the speed of you loads can help you find your most consistantly performing loads.

I usually record the gun used, barrel length, average fps and the standard deviation along with the bullet type, bullet weight, powder type, powder weight, oal, wnd primer type. You could also record the date, time of day, and humidity if possible.
