Josh...It's a shame that the Iowa Game Department doesn't let it's hunters use centerfires...Every state has it's own quirks in it's game laws and it's too bad they affect the type weapons and experience we have in the field...

It does put a different spin on things when you are restricted in this manner...

I'd be inclined to look into a Savage inline if they are legal in Iowa...The fellows that invented it live about 30 miles up the road in Greensboro, they can get you dialed in to long range shooting...

I'm also a member of a NC Hunting Forum, the guy you need to hook up with is 1Shot1Kill...Here is the link to that forum...

I do know that he prefers the Hornady XTP 300gr in .452 diameter...He posts each year on his hunts in eastern NC...We have land over there as flat as Iowa and he has made kill shots over 200 yards with his rig...Must be terribly boring having to hunt to do research and developement...
