Editor: Yes, the vast majority of F-Class Shooters are using high magnification. But 55X is certainly not needed. Plenty of matches have been won with 32X mag magnification or 42X. Our Systems Admin has also used a 45X fixed-power March with considerable success. At my home range, which only goes to 600 yards, the match record was held for many years by a shooter using an 8-25X Leupold.
