Well, I tried a few more today with the chrono.
Had the 150gr zipping along at 2100 with no pressure signs. I did have one round that went 2669? I used the scale to measure the powder for each load and checked the crimp on each one. Don't know what happened with that one.
The 174gr FMJ was going 1625fps with the starting load. It was very consistent with not more than 31fps in the extreme spread.
