I would pick one load and stick to that for the year. Moose really don't require more than deer to kill. Yes bigger and thicker hide but if you place the shot he's coming down. I am not a fan of the avg. bullet, like a federal classic. I only use prem bullets and for this I would suggest a Winchester Fail Safe or Federal Premium Seirra Boattail. I have taken many moose with a 270...140GR Failsafe and they have always preformed flawlessly. My only ? is why would your gun not like all prem. bullets? I have heard of guns not like Rem or whatever but never guys say my gun likes the cheap shells better. I know lots of guys who but cheap shells, but it is not their guns that dictate it.

To each his own, but I think the extra is min. but the benefits are huge. In any regards good luck!
