If you want to stay with a cup and core bullet.....the 180 grain accubond all the way.
If you want a monolithic bullet.....154 HHT, 160 HH or 168 HHT would be my hammer bullet choices. Any of those would work and I would personally go with the 160 HH or 168 HHT. You would have to change your powder to something in the burn rate of H4350 with any of the mono's. I suspect you would be pushing any of those bullets at 3400-3600 fps. With those speeds, I would look really hard at the 160 HH (non tipped hammer). if you go with a mono, you have to go light for caliber as they like speed. It also makes for a really long OACL if you go with standard weight bullets. Check your twist and mag length before buying mono's.
Good luck...should be an amazing rifle.
