[QUOTE="T3-OleMan, post: 713978, member: 14600"] Tod, you are absolutely correct. Don't get confused. When I go to the well I get the bucket full, the excess is free, if anything is ever free. When I go to a real world weather site I get ALL that is there for that elevation. I may need it some day in some other application, and it was ALL real that day! I made a 1 page 11 row, 12 column EXL spread sheet for SC 500' and CO 8k', 9k', 9928' {[URL="http://www.wunderground.com/history/airport/KLXV/2012/11/02/DailyHistory.html"]Leadville(KLXV)[/URL] i.e. Vail} and 11k' with Temps 0F, 10F, 20F......100F as the first Col. All this is for Hornady 185gr GMX Superformance factory round and my zeiss-victory-diavari-4-16x50-t-fl-riflescope, on 338WM. I use the [URL="http://www.hornady.com/ballistics-resource/ballistics-calculator"]Ballistics Calculator - Hornady Manufacturing, Inc[/URL] (this is a new version )and the Zeiss Optical Long Range Reticle Analysis Prog to get the setting for Optimum Power to get max accuracy from my Rapid Z 800. Note that Adv. Hornady wants everything....even still wants humidity? I use REAL station pressure every time I can get it or calculate it cause (being an old pilot) I don't like averaged oatmeal!!!!!!!!!! Can be like the statistian who drown in a creek that averaged 1 & 1/4 IN. DEEP. On my stock is taped reduced / colored-for camo- copy of this sheet. Here is how it works: When I get to hunting site. Record outside temp. Shut the engin off. Set scope for Optimum Power Setting using the temp line @ Elevation. This sheet also reflects the Temp effect on Superformance powder and how if it is 70F and I am 9,928' My GMX 185 goes out at 3,080 fps (on the box)and I must set my scope at 15.27X to get all cross hairs from 200 yds to 800 yds to be ZERO! For 900, 1,000+ yds I have hold over calcs based on the 800yd cross hair. However, if it is 0F my GMX drops to 2,997 fps (-83fps_powder sensitivity) and I have to set Optimum Power Setting to 14.00X. Now all I have to do is get my LEICA CRF 1600 to tell me the accurate Distance to target. I don't have large angle shooting places so I am the only thing that can fail. I can take the pressure. I've missed before and if I get enough opportunities I may fail again? Film at eleven. Note : The CRF 1600 measured Chimney Rock at 1,968 yds as sun set behind it. Yikes!!:D Had two ELK lined up but they would not both fit in the GRILL and under the hood so I stopped:rolleyes:! Dadgummit, only ELK I saw in 9 days. Dang drought was bad last week. Think I'll go ML or 4th rifle next year. [/QUOTE]
