I like Chronys.....
Whilst sighting in my then brand new 35 Whelen, I managed to hit one of the diffuser support rods with a 250 grain round nose Hornady (at about 2500 f/s). The top half of the rod was hanging from the impact hole of the target at 25 yards.
"Betcha can't do that agin, fella."
Then, while fireforming some brass (after checking some other rounds) I got sloppy and put a 115 grain cast lead 30 caliber bullet just .5 inches below the top of the front panel.
Chrony gave me a fair tradein on a new Chrony Master Beta.
I've been lots more careful since then.
