All good info and we even have a bid to go to 130 grain bullets.

Lazyarcher brings up an interesting point about Nosler Partitions. I have not tried them, but others have echoed the same message that they are great performers in the 150 grain bullet, but do not expand enough for deer in the 180 bullet. This is where things can start getting complicated. Does a 180 grain soft-point Core-Lokt bullet perform the same as a 180 grain Partition or is the bullet constuction that much different?

Normally, pointed bullets do not expand as much as round-nose bullets, so will a 150 grain pointed bullet transfer more or less energy that a round-nose 180 grain? I think that majority of posts so far indicate that the 150 will still transfer more energy.
