I've bought Grand Slams for 25, 27, 30 and .338 cals and tested them in my guns for hunting loads and have never had therm shoot good. A friend has had the same experience.

I think they'll work fine for most hunting but 2.5" groups just don't trip my trigger. I've had good luck with other premium bullets such as A-Frames and Northforks and even Noslers Accubonds. I assume Hornady's innerbonds are good too but just never been successful with the Grand Slams.
