[QUOTE="bkondeff, post: 1596648, member: 10444"] First, if you have well developed ballistic data for your guns that you can currently calculate and dial, you have a good start. If you have verified that your dopes are accurate to distance where you are then the transition to WY atmosphere should be relatively simple if you stay in ranges mentioned. I feel 500-800 yds is quite manageable with decent tech if winds cooperate, in real field conditions. I hunt Idaho and move from 9500’ to 4000’ from early to late with no adjustments to scope. I do NOT recommend 300 yd zero. 200 keeps you always well in kill zone, and quick shots make little sense with LR equip. If you have enough adj capability to allow for 100yd zero, fine. 100 or 200 matters not, as long as you have field verified drop data. This is very easy in Idaho. Nice rocky hillsides with faces 300-800yd spacing, a good LRF, good spotter, and phone skope. Now I recommend field verifying you drops at 500-600 when you arrive at your hunting grounds. Make necessary drop adj there but not at zero. Zero adj simply for elevation will be min, but at longer distances can be enough in field conditions to concern you. I shoot 168gr .284 at ~2000. Moving from 0’ to 9000’ is almost 2moa shift at 750yds, while at my zero(200yd) only .3. That’s 15” vs .6”. So set up your system to dial, and field verify. Keep fresh batteries in your kestrel. Only use charts if your tech fails. Use charts for mid of likely hunt range. Dial, breath, squeeze.... [/QUOTE]
