Interesting chrono readings

[Chief 101]

Thanks. I loaded 5 rounds, and will shoot them periodically throughout the day tomorrow, and see what happens.

Thanks.

It may help to keep your ammo at the same temp during this period

Going back through my notes, I have fired this load on a 100% cold bore 3 times. The readings were

3205
3200
3189

That lends its self to barrel heat more than the chrono in my book. Thanks for all the help folks.
