So because it is often discussed as a solution for fire forming, and correcting excessive headspace. I'm in the second group currently. Are there general guidelines on how much bigger the expander should be than the actual caliber. Just as an example if I'm needing a false shoulder in 6.5, should I be using a 7mm or 30 caliber. Does the ratio or size differential the same for all or does it change.
