Ballistic software

[SamT1]

is there a free or $4 app that will calculate windage and elevation adjustments. I've downloaded 3 and all of them have been a bust.

I found a sweet free app that does mildot range finding calculation I think that will help me learn that quick.

It may be easier to just print a card off with my info on it and tape it to the gun or something. But not sure how I would adjust for wind like that.

I'm not sure what apps you've tried, but the free Nikon "SpotOn" app will do it. Enter your cross-wind in the atmospheric conditions settings and press "APPLY" then open the Ballistics Table. Wind drift vs. range for that wind speed will be in column #6. You do have to have reasonably accurate values for muzzle velocity and the bullet Ballistic Coefficient, but the app has a good selection of factory loads built in. If you select one of the Nikon mil-dot scope types it'll show you the ranges for various hold overs as a function of zoom setting.

I've only tried a few other ballistics apps, but they all seem to do what require.

For a range card you typically put in a 10 mph cross-wind and then adjust the drift as a function of range by multiplying drift X current wind / 10. For the Nikon app you can buy a wind meter to plug into your cell phone headphone jack, take a reading with it and them apply to calculate a table for that measured wind value. I've not bought the wind meter dongle so I don't know how accurate it really is.

I use strelok, it gets me close, the biggest variables are whether you've chronoed your loads, know the b.c. accurately, and properly guesstimate the wind/slope.

I hand load so everything I have has been chronyed. Also have a wind meter.

All I don't have is a rangefinder and app at this point. I'm just trying to shoot at pre measured distances for now and learn to use the mildots to range find roughly.

Strelok has been very useful for me so far but it does require inputing all the data before you get somewhere if you want to use it well. I have a Leupold Mark 8 on my .338 with the H-58 reticle. I put 3 rounds at 100 yards on paper to get my zero then used the calculator to go out to 600 yards on steel. First shot was right in the center and the next two touched the first. I got kicked off the range after that as the three rounds put a hold through their steel target. I have a Bushnell CONX 1 mile rangefinder that connects with a Kestrel and a smart phone with the Bushnell app that I'm selling now since I went with the Gunwerks G7. I haven't tried out the Bushnell app since the Strelok app was working so well for me.

I use strelok, and nikons spot on. Both work fine if you enter the variables correctly. I use a bushnell Gforce Dx range finder which stores a number of drop tables.
One of the ways to make it easier is to use your balistics app along with local environmental conditions to pick out a drop table thats already stored on the range finder. At that point you just need to adjust for windage manually on the app as your drop is calculated by the range finder....its a little more work, but i find it satisfactory for my shooting.
