Bedbug, you are reading too much of your own judgement into my post. I said nothing about using the chrony for accuracy. that is your pet peeve, and has nothing to do with why I am using it.

I also never said I was trying to see if my chrono readings would tell me how my ammo would 'perform", that is your wording not mine. I am only referenceing comparative velocities. To be 100% accurate a chrony only measures speed since velocity is a combination of speed and a directional vector and I don't know of a chronograph that measures absolute direction of bullet travel, only that it passes through the sky screen window.

There are plenty of interesting things for which a consumer grade chrony can be used. If you don't want to use one fine, but don't **** on everyone else that is interested in what they can find. I managed to build good handloads for 20 years without a chronograph but now that I have most other equipment I need/want I find the added info from a chrony to be useful and interesting. I also managed to hike for 40 years without a GPS but now that they are affordable I find it very handy.

I think we all agree a consumer grade electronic device will not give absolute perfect velocity readings. My home thermostat is not 100% accurate, neither is my vehicle speedometer, my GPS, my watch or anything else. Yet somehow I muddle through life with reasonable success.
