I picked up a couple of boxes of GMX last year for this year's hunting. I noticed that the 150 7mm is as long as the 154 Interbonds. Hornady X has the BC of each at .525; however, Hornady web site has the CX at .455, so I'd contact Hornady about that. I've loaded Hornady bullets for almost 50 years in 22, 243, 6.5, 7mm, 30, and 338. The theme on the box is true - Accurate, Deadly, Dependable.
