The club that runs shoots on Ben Avery's High Power range is
Arizona Desert Sharpshooters - NRA Competitive Shooting
from oct thru may they run over 100 events. ALL ARE OPEN TO THE PUBLIC
3 or 4 weekend events each month from 600 to 1000 yds and the retired/self employed guys shoot every thursday morning 600 to 1000 yds.
Again that's oct thru may, there is no shade there so they take the summer off.
500 yd shoots at Rio Salado once per month & PRGC, as many as 2 or 3 per month year round.
Nearly all of these events are NRA Prone/F-class (there is also service rifle in addition to the above). The targets are always 6' square cardboard, aiming black is 44" for long range (smaller for medium or short range) but the 10 ring or X rings are quite small, sub MOA for F-class (where scope is allowed).
they almost always split into 2 or 3 groups, with one group shooting and another group working the targets. They fire a 20 shot string then swap positions. Most shooters you get to shoot 3 such strings and work targets for the next guy 3 such strings alternating. (one match is 15-shot strings). Plus 2 to 10 sighter shots per string.
Nearly all the regulars are competition shooters, and competition shooting is about as closely related to hunting as golf is related to fishing. But they always welcome new shooters, mostly in the hopes of getting new competitors into the sport. if you have a hunting weight rifle, you probably won't want to shoot strings of more than 5 due to barrel heating. tell them you're only firing 5 and record misses on the score card for the other shots, or bring 2 or 3 rifles to the line and fire 5 from each. If you show up with a hunting rifle, they usually let you shoot, but they'd probably cringe and 4 or 5 guys would offer to let you try their spare match rifle instead....
when the weather cools down, go shoot with them!
