Mauser,
I've used 180 "Core-lokt" for the past 25 years on Colorado. They kill elk just fine. This year in my camp, 3 hunters all of us used 30/06 with 180 grain "core-lokts". 3 dead elk. 3--1 shot kills. Ranges 250 yards, 200 yards & 125 yards.
Plain jane "Core-lokts" work just fine on elk. But if you have more faith in partitions thats OK use them.
