What is the best way to check a chronograph and make sure its accurate ??

[viper9696]

put it in line with Hammer's 7 linked together chrono and see how it rates. ;D

I try mine against all others I come across just to see how it stackes up,found mine to be close enough for me,some read higher soom lower so I'm gtg.

I use match grade rimfire ammunition as a reference. If at room temperature ... subsonic 22 rimfire ammunition is just as good ... just dont leave it sitting in the car on a hot day ... because it wont be subsonic anymore. ;D

I went trough some of my old chronograph notes on factory cartridges and
now I think its pretty close. I just have a couple of loads I expected better
results out of

I have some Wolf 22LR target I will try out.

Thanks

I have set aside a couple of boxes of Wolf MT 22LR ammo with the same lot number just for checking my chrono. So far it has been very consistant.
