No truer words have been spoken.
OP- you can go the old school method as well & add an ACI/ADI to your rig that will give you the correct cosign or angle for inputting into you ballistic calculator. This setup offers a few pros as well as a con or two versus using your ballistic calculator.
It's attached to your rig, you don't need a third arm to try to steady a slippery phone or Ipod on your rifle somewhere. It's not electronic, the batteries never go dead. It should provide a little more consistency as well.
It's another "gadget" you have to buy & they ain't cheap. If you're a Southpaw like I am, finding one that you can swap over to the "correct" side of the rifle can be frustrating. It does stick out from the rifle some, some folks don't like that.
