I'm looking to rent or borrow a chronograph for a day so I can make sure I meet PF for the Area 2/Rio Desert Classic this weekend. Does anyone know of a range that has one I can rent or use to make sure my ammo meets it? I'd prefer something on the East Valley if possible. My data puts me at PF of 144, 147 gr bullet going 980 at the muzzle, I just want to double check before I shoot the match for no-score.

Idk of a range that has a chrono for rent or even "out and about" but id think if you go to the range enough there should be someone there shooting and has a chrono out.  Just ask if u (or if they prefer, themselves) shoot a few rounds over the chrono.
