6MM Ackley Qestion

[Tobey284]

Found a 6mm improved at a gunshop today. It's a rebarrelled ruger No 1. Pretty interesting rig. Barrel manufacturer and gunsmith are unknown. I've never loaded for any of the improved chamberings. I have read that bolt actions should have the barrel set back a thread to provide a crush fit in the chamber during fire forming to prevent case stretching in the web and subsequent head space issues leading to case failure after one or two firings. How does one get a "crush fit" in a single shot chamber without the camming power of a bolt action? Any other possible issues I should consider? Going back monday for another look.

You can neck up 6mm brass and then run the die down until you can get the action closed with resistance. You can also seat the bullets into the lands to help with fire forming.

if chambered properly, the AI line headspace .004 shorter than the parent case so just load 6mm brass and shoot.
