[QUOTE="Mysticplayer, post: 87598, member: 8947"] Kirby, that's what I like to see, predictable 'linear' ballistics. I can see that you aren't going to need to dial up much with that reticle. 4.5mil X 3.6min/mil= 16.2 min to 990yds. That is nice and flat. I assume just a bit high for a 100yd zero (maybe 17.5 mins from a 100yds zero???). My 7RM and 162gr Amax at 3150fps needs about 18.5 to 19.5 mins to 1000yds (940yds is 17.5 so extrapolating to 1000yds). What type of rangefinder are you using? When you generated your drop table, which G function did you use? The most important thing is that the wind drift is really low. That matters more then just about anything in LRH. 1 mil of wind drift in that type of wind is superb. For those not that familiar, run the numbers on a 175grMK from a 308. You are working way too hard to dope this cartridge. A enormous benefit of that high BC is the retained velocity. That just ensures consistent bullet expansion and a good wound channel. Me guess Mr. Whitetail is not going to run far with a 4" exit hole. Not too far at all. Good luck on your hunt... Jerry [/QUOTE]
