The distance used for the long range match is dependent on the facility of the host range. We use 300 yds here at my range, but have seen it as short as 100 yds. Skirmish match targets are usually set at from between 15-100 yds with the majority of them set between 30 and 75 yds. again, the distance is dependent on the facility.
I will use 2 different loads, one, a lead bullet, low velocity load for the skirmish match; and the other a jacketed 220 grain round nose bullet pushed at 2100 feet/sec. for the long range match and hunting.
