You've resurrected a very old and somewhat long/confusing thread. As a new reloader, please forget "depth in case". It is difficult to measure. The more relevant thing is case volume behind that bullet - even harder to measue

If you have two cases otherwise identical but with slightly different lengths . . . and seat two identical bullets in them to the same overall length . . . the two cartridges have identical internal volume despite having different amounts of the bullet in the case! Seat them to the same depths and they will have DIFFERENT internal volumes, and different pressures.

So as a new reloader, check the maximum OAL for your caliber (for 9mm it is 1.169") and DON'T GO LONGER THAN THAT.

Then find a recipe for your powder that uses the same bullet, or one close to yours in shape and size. EG Hodgdon Reload Data for 9mm, 115gr LRN, HP38. Check the OAL listed in that recipe (1.100"), and DO NOT GO ANY SHORTER THAN THAT (for the time being).

Any OAL within those boundaries with any powder charge between the listed min and max is a safe combination.

Many folks want about a caliber's length in the case for sufficient neck tension (~.355"). But the fact of the matter for pistol is that the best OAL is chosen by your pistol.

Min and max length cartridges are least likely to feed, although my own loads are set at 1.100" for any RN bullet. Something close to factory ammo's length will likely feed well.
