Well, I live in Iowa also, near the QC. Our Whitetails here in Iowa are pretty large, both Buck or Doe, than in a number
of other states. A deer killer proven, is the Military Classic 124 gr. HP which has the M83 I believe it is bullet. From the
ULY arsenal. Not the 122gr, only the MC or Uly labeled 124Gr. I have used Wolf 154 gr SP, not near enough expansion
Otherwise, buy US made hunting rounds. JUST BE SURE the US ammo has a .310 or .311 dia. bullet. Not .308.
