Need help with .30 bullet selection

[CptCurl]

The .38 Super Competition brass doesn't have the semi-rimmed case of the .38 Super. It has the same head as a 9mm Para. That's the point of my choice of that brass.

In addition to the slugging of the barrel for dimensions, one might also pay attention to the chamber neck area, one has to be able chamber easily and also let go of the bullet.

This point should be stressed, and it applies to every cartridge. There must always be sufficient clearance within the chamber for release of the bullet. I was mindful of this, and mine is ok with the .312 and .313 bullets. But again, just because mine is ok doesn't mean that every pistol is ok. This determination must be made for each chamber.
