Rifles are like kids: they each have different appetites.

I've found my '06 likes 165's better than 150's, 180's or 220's. Among the 165's though, some shoot well out of a clean barrel, but not a dirty one. Oddly enough, others like a dirty barrel, & won't group for a hoot out of a clean one.

'Tis my understanding that the '06 won't push most cup & core bullets so fast that they'll come apart, so a "standard" 165 to 180 bullet oughta do fine for moose & deer. You can try Corelokts, Power Points, or Hot Cors, & see what your riflelikes best.

Or, if it will put your mind at ease, you can step up to the bonded bullets like Accubonds, Scirroccos, or CoreLokt Ultra's. They'll stay together better when crunching bones at close distances, and will give generally deeper penetration on moose. They're also designed to still offer some expansion, too, though not as much as the standard bullets. FWIW, I've gotten excellent accuracy andperformance fromHornady Interbonds.

Try a few different loads to see what your rifle likes, then go shoot a bunch of it to get comfy with your setup.

Good Luck,
