Go to theFederal cartridge site and download their interactive ballistic tables. It takes into account temperature, windage, elevation, and different sight indistances. The other cool thing is you can print out the stats on your cartridge in landscape mode, cutout just the table, and shipping tape it to your stock for your trip.Covering the piece of paper with shipping tape pretty much water proofs it too. You will have bullet drop as well as windage results right where you need them. It would be a shame to makea mistake onsomething you can prepare for ahead of time. The only down side is that you eliminated a lot of the excuses as to why you missed.
Oh yeah, I second the Accubond vote, especially in 180 gr.
