I’m just stepping into aggressive shooting six.5 CM within an RPR) and I’ve selected H4350 various months in the past after reading the many analysis I could obtain on its temperature balance.
It in fact tracks the bullet out to about eighty yards, getting numerous velocity readings along just how. The muzzle velocities collected proved to generally be quite identical between The 2 products, which gave me plenty of self confidence in the data. Both of those units appear to be considerably more accurate and dependable than conventional mild-based mostly chronographs.
