I just found out about this BT knob from High Power Optics and bought one. Unlike other turrets that fit over the BT marking rings, this one fits in place of the rings. The knob fits perfectly on the turret and has knurls for better grip. It uses replaceable labels, so I can re-use the same turret knob for a custom ballistic label. Cost me $60 for a standard IPHY knob and four labels.
I just confirmed my 7 WSM bullet drops at 500 and 700 yds, and ordered a custom ballistic label. I’ll update after I get a chance to shoot it with the custom label.
