Any particular type of laser range finder that people really like for this kind of thing?
I recently broke down and bought a LRF. Luckily at the Missouri match I had a chance to check out several different makes and models. Swaro, Leica, Vectronix, and some Bushnell stuff is what is being used most of the time. Lasing reliably beyond 500 or so is gonna be a bit pricey. The Swaro Laserguide is by far the best bang for the buck, and I was able to pick up a very lightly used one for $600 (normally $1000 new).
Assuming ya'll don't want to spend too much money on your first match, I would skip the LRF and get aqcuainted with mil relation formula (even if you are buying a good LRF, you should at least be familiar with mil relation as a backup). You should be able to get a reading, and run the formula, within 10 seconds. If you can do that, you'll be fine. Target dimensions will be given prior to the stage for any UKD, so you can have your constants already worked out, and it is a single division problem from there.
Complete formula:
( Target size in inches X 27.8 )
Mil readingEquals target range in yards
Two part formula:
(Target size in inches) X (27.8 for yards) = ConstantThis is the part that you can do before the stage, although you may have more than one constant to remember, so I would make a sketch. I actually have a giant sheet of constants in my databook that I can reference, so this part of the formula is already done for me.
(Constant) / (Mil Reading) = Range in yardsTarget is 24"x24"
Reticle is Nightforce MLR (Similar to Leupy TMR)
Mag is set correctly for ranging
24 X 27.7 = 666.48
Mil reading is ~0.8
666.48 / 0.8 = 833.1 yards
