i new to chrono's and my first was a magnetospeed v3. had some shots that wouldnt clock but normally pretty good.
picked up a xero c1 last week and noticed it clocked faster on 2 of my 308 loads by 100 fps and 75fps BUT it was spot on with the 223 ammo tested.
i figure it was the magnetospeed being off because sometimes it would come loose and not read. glad to have the xero since the v3 seemed hard to get tight to the barrel and it works with everything. i have some rifles with rails out to the end of the barrel and am not interested in setting up an old school chrono.
