Thread: Impossible 6mm ??

I'd like a 6mm that will deliver a 105gn (or thereabouts) at 3000 fps with decent brass/barrel life. Easy until I say it must do it with a 20" barrel and a COAL of 2.4". It's also gotta feed reliably. I have a 6mm ARC but it's maxed out at 2880 fps with 22". The 6mm CM but is too long for my new action and the one I had didn't have a nice node at 3000 fps.

It's gonna be a hunting rifle.

Tell me about possible candidates like 6mm Dasher, 6mm GT and others in a NZ context.
