Sidroski,
We shoot here in Wayne Co. on a private range at the Wayne Hunting Club. It is not necessary to practice at 1000 yards. I do all of my load development at 300 or 400 yards. The IBS competitions are in TN, NC, WV, VA, OH, MO, MN & CO. Most of the ranges during the summer will not be that big of a difference than South MS, maybe in humidity. We have a 6 minute sighter period before record fire. During the sighter period you shoot at 4.5” Clay pigeons on a dirt bank. It is no big deal to get on target. No I don’t fly my guns. I drive to each match.
