How accurate are these chronographs. I just bought one and tested out a couple of loads for my 270 WSM.
70gr of Reloader 19, Rem 91/2 primer, winchester brass, 130gr Hornady bullet, 24 inch barrel in my Sako A7 rifle.
registering velocities of 3759, 3768, 3761 fps = seem way too fast.
sunny day, about 90 degrees and I was following directions included
unit was about 12 ft away from muzzle.
