I have shot many brands of factory ammo in both of my 7mm-08s, but the most accurate ones have been the light magnums.
I have only used the BTSP, not the SSTs, both on paper and on game. The 139 BTSP light magnum hit with some authority despite the fact that they are little. I have used them on deer and they work great. The exit wound was a nice size and the deer didn't go more than a 10 yards or so.
The 7-08 is my favorite deer cartridge, and the light magnum ammo is my favorite ammo for the 7-08. :grin:
