The 30-06 is more gun than you need but will sure get the job done. It will shoot plenty flat enough with 150-165 grain bullets. A hit throough the vitals will reduce meat damage. I like the 270, 280 or 25-06 pretty well for long range deer and pronhorns. I have used the 243 as well. It ok with Nosler partition bullets or the new Ballistic tip in 243.
