Crimping 9mm on bullets without a groove or cannelure is nearly useless. Case tension on the bullet holds 9mm rounds together.
I've seen factory ammo pull out on those small Rugers.
9mm automatics tend to try to push the bullets deeper into the case during cycling and under recoil. 9mm was not designed for revolver use.
As a reloader, you can do something about this. You need both a standard and an undersize sizing die. You also need standard and undersize expanders. Lyman M-type expanders can easily be undersized with a drill and a stone.
Experiment with different combos of sizers, expanders and bullet diameters by making dummy rounds. For example, Remington brass is very thick, needing only a standard sizer and expander to give strong tension on .356" bullets. FC brass is very thin and needs an undersize sizer and expander for good tension on .356" bullets. For loading .355 bullets, WW brass is perfect with a standard sizer and undersize expander.
The possibilities with different headstamps of brass, dies and bullets is endless for getting that case tension right.
Also, those cases need to free of ash where the bullet sits. Ash acts as a lubricant. Get it all right and enjoy those small 9mm revolvers!
