The partition is the benchmark for performance, that's for sure. I've killed many, many big game animals with both partitions and accubonds, and I haven't noticed a difference in killing power between them at all.
Agree.
I sorta like the NPT just because, but IME, the gun decides which one it likes and I go with that.
NBT's often will out group NAB's of the same weight, etc. Because the 180 NAB and 180 NBT have the same B.C., same POI in my .300 WM, I alternate depending on what I'm hunting. My .240 Wby shoots the 100 NPT tighter than any other bullet, so it's the one for that gun, an HS Precision SPL wearing a Hunters Edge handle.
So, the rule is there is no rule. You find what the gun likes and go kill stuff.
