I just returned from the 25yd indoor range. I am very pleased with the results of my little rifle and big SWFA SS 12x42 MIL-Quad scope. I used the following ammo: 1) New PMC cat# 223A 55gr FMJBT and 2) New Federal XM193 5.56 NATO 55gr FMJBT. After sending 4 PMC bullets down range the rifle was sighted in at 25yds. The next 3 shots measured .215 inches center to center at the widest distance according to my RCBS micrometer. The total spread of these 3 bullets was .420. These 3 shots were fired with PMC ammo. The next 2 shots, one with PMC and one with Federal were in the same hole and the diameter measured .288. This compares to a single bullet hole with a diameter which measures .220. I understand if no ones believes these data. The system says my photos are to large. I cropped them to make them smaller. I am not good with photos. I hope you can see the results. The bullet hole to the left of the 3 holes is my 4th and final sighting shot. My total investment is about $950 for a little rifle, big scope, rings and 20MOA rail that shots inexpensive ammo accurately enough out to 300 to 600 yards. I am ecstatic about this experiment/project. I will be selling my Winchester Model 70 Extreme Weather SS.
