I finally broke my Remington 700P (.308) out of the safe today to get it sighted in. 100 yards was pretty easy and I'll get it dialed in at 200 yards next week. What I really want to do is take it out to 500-600 yards or more . Is there anywhere around the DFW area (within an hour or two) that this is possible? Anyone here shoot distances like that and want to share some pointers? Thanks in advance.
