I shot a lot of Remington Core-Lokt in 150gr and 170gr through my Marlin when I was shooting factory ammo. The only difference was the 150gr hit just a bit higher at 100 yards, both were accurate. I now shoot mostly reloads, but still keep a box or two of Hornady LeverEvolutions around. When I get ready to order more 30-30 bullets I'll get some LeverEvolution bullets to load my own.
Keep in mind when you're at the range, the 150 and 170 flat nosed Remington bullets will hit lower than the LeverEvolution rounds. I would sight the rifle in with the Hornady then just hold the crosshairs/sights high to compensate for the increase drop when you're target shooting or plinking.
