RE: Hornady 7mm-08 139 SP
I own two 7mm-08s, and unfortunately neither of them care for Hornady factory rounds. Rifles are fickle like that. Yours may well love them above all else.
The Hornady SP Innerlock bullet is an excellent design, and will serve you well on medium game. As long as it shoots well out of that SPS, it will lay them out in the fall.
