I bought a chrono and it's a fairly low end one, because it was affordable.
So I'm suspecting there may be some error.
Loads that are listed as having a particular velocity are slower than expected, in the testing range between 2000 to 3000 FPS
So I fired some factory loads : PMC - 308 - Winchester - 147grain FMJ-BT, from my rifle with a 20" barrel and I got 2550 FPS avg.
This is about 200 FPS slower than what's listed on the box.
Which supports the idea that there may be an error with my chrono, because other loads I've tested have been about that much slower than I'd been expecting
Has anyone else chron'd those PMC loads to see if the velocity matches their advertised?
I'm actually leaning toward having to get into troubleshooting my chrono.
It's a Pro-Chrono Digital
Thanks in advance - Any advice appreciated
