I settled on the 100g NBT. It acts wonderfully at 6.5 Grendel velocities. Out of our Howa Mini Action it gets ~2600 fps with a max load of TAC. Very accurate and easy to shoot. My kids have taken 5 deer ranging from 150 yards to 250 yards. All but one was a one shot kill. The one that wasn't was shot through the lungs and when he turned, we good see good blood on the opposite side. One more shot and he was done. That was the 250 yarder after the first at 241 yards. The only problem with the 100g NBT right now is finding them. I might have to go to 120s after this year if I don't find some soon.
