I am in the market for a variable power handgun scope to put on a Browning Buckmark Varmint. I found this one from Nikon with a BDC reticle but cannot find any info from Nikon on what it is calibrated for. SWFA website shows 200 and 300 yds. with a 100 yd. zero. Sounds a little extreme for a handgun scope. Does anyone have this particulat scope and is able to give me any feedback on it ? Any input is appreciated..thanks
