170 gr Nosler Partitions and RL-15, have a modern 26" octagon barreled 30-30 Winchester that fires these to 2400 fps, you guys wouldn't believe what they will penetrate through, nice accuracy from the Lyman receiver peep to boot.
The .30-30 has surprised me more than once.
I can believe what that bullet will do at 2400 fps. A .308 with the 170 Partition at 2500 fps is a penetrating, animal-killing, woods-hunting monster.
