App or computer program for variables

I have a 300RUM and Leupold scope with turrets marked for yardage. The yardage is based on 4500' elevation and 40 degrees with 210 Berger VLD's. It has worked well and I have been able to verify the turrets are correctly marked for where I hunt elk each year. I am considering going out of state in search of a big one and most likely that will mean different elevation (higher). Does anyone know of an app for my iphone that would give me the appropriate yardage setting given a true horizontal range and known temp and pressure?

Re: App or computer program for variables

The apps will not return a yardage setting. Just a click adjustment.

If you know how many clicks to your yardage marks, then it it not hard to add/subtract the needed adjustments. The custom turret will be good to around 400 to 500 without any adjustment. But from there on out, you will have to +/- at different intervals depending on the variable adjustments.

You can create a cheat sheet in advance, if one or the other variable is known. Elevation would be the easiest to be known.

Thanks for that information. I will make up some cheat sheets and hopefully get a chance to test them before long.

You may check the g7 program as it may output in yardage, not positive though. You could also have a turret tape made by custom turret systems for another elevation!

Re: App or computer program for variables

I did just get the shooter app for my phone, and playing with it last night it looks like you can set it for 1/4" or 1/8" or yardage turretts. It has more adjustability than I expected. I have not been able to fine tune it to tell for sure, but some of the other guys on here can probly answer issue: but I would think it has what your looking for.

they will give you an moa adjustment, shooter will automatically factor in angle and if you have a kestrel with bluetooth it will also take care of atmospheres, you still need to verify all the fields, verify range and dope the wind. having a dope card handy, the ability to reticle range to verify outputs is very handy.

I just got kindle fire a couple of weeks ago, bought the shooter app first thing. So far its been spot on, and pretty stinkin fun to play with
