i use winchester 180gr silvertips , and i hunt moose every year, they have never let me down, i have found that you dont have to waste money on the premium or ultra bullets, the regular ones will work just fine for you. i bought some remington 180 PSP core lokts to try at the range but havent had a chance to get out, but i think even if they work good i will still stick with the silvertips, like i said they seem to work great in my 30-06.
