Newbie here, just got a cz 527 carbine in 223. Has a 18.5 inch barrel with a 1/9 twist. Looking at a good deer bullet. I know some folks are skeptical of them, that's not what this is about. I'm thinking I want to use the heaviest bullet my barrel will stabilize. Anyone have any experience with any 223 deer bullet? I see federal makes a 62 and 64gr fusion, also seen the 60gr nosler partion and I've seen some barnes ammo. I need factory loaded ammo since I don't reload.
