I picked up a prefit barrel for my ARC Nuke. It was a really good price, so I dont mind tailoring the bullet to the existing freebore instead of vice versa. Not really a competition shooter, just like banging steel and printing tiny little groups. The barrel has a .105 freebore - which heavy class bullet would be suggested? Ive read it may be too long for the 105 hybrid, but the 107 SMK and 108 ELDM would be just about right - any truth to that?
