FYI post. I was there yesterday. The club is now operating under summer hours, 7 - 3 rather than 9 - 5. Qualification for shooting at 600 is shooting a 6" group or less at 300 and knowing the dope to get to 600. There is steel at 200 and 300 on the public line. Every distance on the public line has huge berms now.
The PRS match is the 1st Sunday of every month so the next is the 5th of August. The 600 line should be open after the match.
