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

I've used one for years when working up a new load.

A friend often downplayed the need until I watched him 'splash' a 270 130 gr partition on a little hill country white tail's shoulder. He used my rifle and finished her off.

I happened to have my magnetospeed in the truck and when we got back to camp I had him fire 5 rounds over the MS. Results were that his handloaded 130 gr was running around 2400 fps instead of the 3000 or so it should have. Ran the rest over the MS and results were the same. Seems he found an accurate load and stopped.

He now has a MS and another chrono he got from Fleabay.

He also found an accurate load for his 130's that's much closer to 3000 fps as well.
