So I am doing my first Savage 110 rebarrel job on my .300 win mag. I have the fosters go and no go belted mag gauges. I know it headspaceing off the belt. I also hand load for this gun, and many other guns.
So my question is, how tight do y'all like the chamber to be on the the go gauge? Just barely able to close? Easily able to close on the go gauge but not on the no go?
In my case, the only time a cartridge will headspace on the belt is with virgin brass... Because once fired they will space of the shoulder/datum as I neck size after that. But I want a saami spec chamber or I would just headspace on a sized piece of brasses shoulder in the first place.
My initial thoughts are to make it tight so the brass grows the least, Which is inevitable on a .300 wm (they can grow as much as .020 in a saami spec chamber). But I just wanted some opinions on this topic.
Thanks for any replies.
