In practice, these points tend to significantly cut back the out there magnification range on FFP sights compared to SFP, and FFP sights are much more expensive in comparison with SFP fashions of related high quality. To ascertain the suitable elevation setting the shooter must enter the ammunition kind into the BORS (using touch pads on the BORS console) decide the range (both mechanically or by a laser rangefinder) and crank the elevation knob on the sight until the proper range seems in the BORS display.
