Thanks, you've given me an excuse to get one!

That was my thought, too.  I'm debating on running to Scheels and picking one up this week so I can (hopefully) try it out this weekend.

I'm just glad I have until November to get myself up to speed.  Because it'll probably take that long to get it so that my rifle and I agree on things past 300 yards!

SeanN:
If I had (or could afford) even half the equipment for this, I would sign up...

But as it is I only have red dots on all of my rifles (with a 3x magnifier that will do virtually nothing to help at that range!) and I have no other equipment that would help here.  ???

The only place I have to shoot long range is the family farm 3 hours north of here, so getting everything set up is going to take some effort.

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 reading
Equals target range in yards

Two part formula:
(Target size in inches) X (27.8 for yards) = Constant
This 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 yards


Target 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
