Anyone bought one of those cheap Chinese chronys off that auction site?

[Phil Russell]

Thanks guys.

I was thinking of writing one out (for quick evaluation) but is there a crib sheet/excel graph or whatver online with given calculations, ie left hand column reading say feet/metres in 10ft increments of 200 fps to say 800 fps and along the top given power for certain grains ie 5 thru 20 etc?

Yes there is. Not sure where I found them but I have just sent copies (Xcel sheets) to your e mail. I hope they turn out OK. I printed mine out and laminated them as a quick guide.

Cheers, Phil
