RE: 7Mag--Hornady Interbond
I used 139 gr IBs in my 7mmRUM last year. I had them really revved up (around 3600fps), they shot great and worked better than expected on the buck I shot. I bought two more boxes (7mm 154gr and 30 cal 165gr) to load up for this years season in my 7mmRUM and 300 WBY.
Good luck.
