Thread: 6mm ARC - What would yours look like

This here is exactly why my 6x45 is in danger of being relegated to the bench. This reality dawned on me when I saw it and the model 7 side by side in the safe - the M7 action is basically the same size as the ‘little’ BSA Hunter, but has so much more power capability. Why try and wring the neck of a small cartridge when I can use a bigger one, in a package the same size. With no disadvantages…. Except a bit more powder burnt.

The ARC has merit in a true mini action, for a niche capability I think. I had contemplated it to go in the BSA action, but after this revelation, I won’t be.
