Home Forums Hunting & Shooting Ask The Gunwriters Chrono, Yes or No

I'll add one thing that wouldn't be easy to solve without a chrono. Differences in powder lots.

I had to bump up a max load of H4350 by 7/10 tenths of a grain, with a new can of powder, to achieve the same accuracy and velocity. I would have been reluctant to experiment with a higher charge weight without the chrono.
