Thread: Inaccurate Cartridges

A bullet which is perfectly balanced on the rifling axis is less like a corkscrewing aerobat before its spin eventually stabilises it at some point of its corkscrew. This is why some large groups often describe circles (with the centre less densely holed, rather than a uniform peppering of holes covering the entire area of a circle).

Yes but would be mitigated by close chamber dimensions.

I was hoping someone may have burnt a couple of barrels in a target rig with a long case and gone to a short and fat case in a apples with apples comparison.
