Which bullet? A 60g Partition or a 500g Partition at 1800fps? Nosler claims the same "Optimum Performance Velocity" for both (1800fps to unlimited fps).
Neither. The .223 bullet doesn't make a big enough hole and the 500 is ridiculous. I'd use one somewhere in the middle that makes a big enough hole without the recoil of a 500 grain bullet.
Which do you prefer? Let me guess, the 500.
Either mass does not matter, as you claim --- or it does, as you also claim.
I've made no claims about mass one way or the other, dimwit.
