Ok, my first Chrono arrived this week and I've set it up and played with it. What do you consider to be a good high/low difference in FPS for handloads on a progressive press?
I had a batch of .500 S&W that I loaded on a single stage and dropped charges with a Lyman Model 55 powder measure and it was all over the place. I suspect this is because I contaminated my primers but I'm not sure.
On the other hand I had a bunch of .45acp that was staying within 10-15 fps over 10 shots with shots 11 and 12 being outside that range by another 10 fps or so. (higher an lower). I was pretty tickled.
Anyway, just curious as to what variation you see in FPS and what you consider 'good'. (as in your reloading correctly with your progressive press)
Have a good one,
Dave
