Bought my wife a Mk II in 280 Rem 20 + yrs ago, It is a dandy combination. It loves 150 grain bullets and as Todd shows, they don't have to be premiums.
Though I finally developed a load for her using 150 grn NPT's and RL22, she did just fine with 154 grn Hornady's on pronghorn, deer, elk, and even moose.
As for the Hawkeye's, just like its predecessors, they are darn good rifles. The 338 I had was a moa rifle, and the 7mm Rem Mag I shoot presently is sub moa,
though honestly I did have to float the barrel to get it to settle down.
