If you plan on sorting cases by the velocity they produce, then forget the Crony because they are just too far off and too inconsistant.
My two Cronys were always reading different than each other on the same shots, alternating one being faster than the other all the time. They were so far off it was maddening to say the least.
I see no value in the inconsistant inaccurate data the Crony brand delivers. A reloading manual is more accurate at giving you an idea of velocity for a load if that is all you want. Within a 100fps or so a manual will do, the Crony won't. So why even spent the $100. on the Crony if thats all the accuracy needed? Besides that, what would an accuracy of twenty to fifty FPS be used for?
A Oehler is a accurate TEST instrument used for MANY reasons beyond just an idea of VE.
I had a 5" Taurus 454 spittin 310gr slugs at around 1650 to 1800fps, ya 5". And my Ruger 416wby with 400 grainers at 2550fps. That was over the Cronys.
When I got the Oehlers they say the 454 is ALWAYS at 1500-1520 and the 416wby ALWAYS at 2650 to 2675 fps.
I have the Oehler 43 and the 35P both and I won't sell or loan either of em.
Hey Ric, most hobbies aren't cheap, at least my wife tells me mine aren't. She points to my 1000 dollar remote control airplane hanging up there for one.
