There were I think 5-6 targets past 900 this year. Most everything is 200-800yd. Targets for the most part are pretty fairly sized considering the hunter divisions and people are using factory rifles/ammo, but the long targets are no joke.
Weight limit to get into the "Hunter" class was a 10lb rifle. My partner's rifle wasn't even close so I didn't quite catch all the rules on what can/can't be off the rifle for weighing.
30% score for time (8.5-9 miles with about 800ft elevation change, avg. around 5500ft.). I think it's percentile of the best time?? Not 100% on that one, 70% for targets. 3pts 1st round hit, 1 point 2nd round hit. Each guy fires 2 shots at all 40 targets. Shooting well pays off more than running fast. I've done it the last 2 years and did much better taking my time. If you want to be serious you probably need to physically train regardless. The guys that win it shoot great AND haul ass.
I don't know if I'd recommend a magnum. I think a guy got scoped pretty hard this year shooting a 300 RUM. Could be wrong but I think he had to go get stitches. The shooting positions can get funky and magnums will exploit lack of recoil management or bad position.
