I was thinking along the lines of one of the lead cored premiums. Midsouth presently has some of the Hornady line of Interbond blems at a serious discount. Shooters Pro Shop sells Noslers of various types and weights - 2nds- at a great discount as they are available. One of the sleek 165s might be advantageous if retained speed is a concern.

Sometimes, the air you 'let in'matters less than the air you 'let out'.
