1/4 inch clicks question for drop charts

[djtjr]

Guys I'm doing a tough mountain hunt in August and wanted to take a lighter weight sheep gun with me. I have 2 guns that would work well and both carry a Zeiss Conquest 4.5-14 with target Turrets on them. The issue is that the click value on the scopes is .25 INCH @ 100 Yards rather than .25 MOA @ 100 Yards. For the first hundred or 2 yards that doesn't matter much but both are capable of accuracy at 5 and 600 yds and thats where the .047" difference between true inches and MOA starts to come into play when making my drop charts because all software i have seen and have is in MOA. Is there a software that will do true .25 inch clicks rather than MOA? If not how do i calculate for that difference so i can be spot on at the longer distances rather than a few inches off? I don't love the idea of messing with velocity inputs to get them to line up as my OCD would drive me crazy and while that may work on one range I wonder if it would cause issues in the program when heading to altitude? Any thoughts. Lets assume Ive verified that its a true .25".

The G7 program allows you to choose the inputs you're looking for.

You can account for this with the Applied Balistics Shooter app. You can do .25 or MOA when entering the parameters for you rifle and it is saved. No sweat.

Shooter does it, it is IPHY. " inches per hundred yards "

+1, It's IPHY.
Ballistics app on my phone has it and so does JBM. I think even my old Palm with exbal has it.

Yup Ballistic and Ballistic AE will output in 1/4 IPHY, and even non- fractional click values like 0.245 IPHY.

iStrelok will also do IPHY, also known as SMOA.

Correction. You are ASSUMING they are .25. However scopes are routinely off mftrs stated specs. Run Brian Litzs tall target test to find out what you actually have and then apply corrections if needed.

The shooter app on my Iphone will do inch per 100 yds (IPHY), MOA, or Mils. Most ballistic programs out there will do IPHY. If yours doesn't do it then it's a simple matter to find one that will and switch to it.

+1, there is a little discussion about it going on here: http://www.longrangehunting.com/forums/f17/tall-target-test-video-comments-155589/

As has been stated you can find iphy in most ballistics progrsms, but if you don't take the time to validate your scopes travel through a tall target test and a box drill ...your just asking for problems.

Ballistics programs are great for educated guesses. Spending time at the range is the only sure way to know your equipment. Spending money for the hunt deserves time spent knowing where to hold. Good enough for Brian, good enough for me.
