So, the NRA have opened it up on certain days for individual members (up to 6 am or pm):
8:30 meet outside the office for a range brief, drive round to the entrance, RO lets you in, another brief.
9:00 - 12:25 shooting from 2 firing points, 2 shooting, 2 spotting (spotting scopes provided). Roughly 10-15 shots each before swapping.
Dry and low wind on Saturday, so fairly easy going.
