The load is developed, the new IOR 3-18x42mm is mounted and bore sighted, the rifle is basically set up and ready to go. I should be getting Exbal and Palm by July.
I want to now develop a 1600 yd range card. I figure to start using http://www.eskimo.com/~jbm/calculati...raj_card.html.
Their are some entries which I'm not sure of. The following is what the entries are.
-Nosler 30 cal 180 BT
-BC of .507
-Muzzle vel 3050 fps
-Chrono screen distance of 10 ft from muzzle
-sight height above bore = 1.9"
-sight offset? What's that?
-Azimuth? What's that?
-Zero height? What's that?
-LOS angle? I assume Line Of Sight?
-Wind speed, I'll put in 1mph
-Target speed, what is the walking speed of deer/elk
-Zero range, I'll put in 100 yds
-Temp. I assume I put in the expected temp on the day I'm shooting
-Pressure. Where do I get that?
-Relative humidity. where do I get that info?
-Altidude. That one I know how to get!
-Vital zone radius. I assume if 10" is the vital zone of an animal, that is the entry; 10.
-Drop units. Does it matter if inches or MOA?
-A few of the next 6 checked boxes I think I understand, like Range in Meters would be meters instead of yards/ and / Zero at Max PBR /The first 4 i'm not so sure of. I can guess but would prefer help on.
Thanks for any assistance you can offer.
