After my last Caldwell chrono failed, they gave me a new one free. Great! But now I have two problems with it:
1) Far too many e2 errors. I might resolve this by stabilizing the chrono mount system a bit more...
2) About 20% of my data shows some really HIGH velocities: as in 5182 or even 7789 fps!!! No, there was no decimal point error there. These were MODERATE rounds, hand-loaded meticulously, and the brass/primers/recoil showed NO signs of high velocity.
Is it possible that the small rifle primers I am now using consistently sometimes get a high-vel spark past the chrono far faster than the 140 gr bullet? ( on 7 gr HS-6 powder) THANKS!
