I'm putting together a 6br on a Tikka for PRS stuff this year. It's going to sit in a Whiskey 3, Gen 5. Barrel is a 26" MTU (with smaller Tikka shank). Obvoisuly I'll have to wait for the barrelled action to fine tune ballance, but I'm wondering what I should be thinking about in terms of which weights to start with. I'm guessing a heavy flat bag rider, and a heavy arca rail? There are limited spots to put exterior weights on the forend, so the weighted arca seems like the obvious solution. I assume the forend t slot and the weighted arca will just make the whole thing too muzzle heavy?
