Started out with a Chrony back around '99 and it still works fine albeit at the home of a friend. Pro Chrono showed up several years back and I have no problem with its performance. I never was one to pursue high velocity with any firearm, preferring precision instead.
I was a bit bemused to discover that low velocity spreads were not the Holy Grail. That came to light one day when a 5 fps spread was FAR less precise than 25 fps, this with a .338 Win.
ahumm - Oh yes, my friend. You'd 'think' that 'consistent' velocities INDICATE an accurate load . But NOT necessarily so.
There are other things that enter the equation. So far I haven't found THE thing most important to tell me what an accurate is........
other than shooting groups.
