My first time firing a GP100 with .357 (only .38 Spl. previously) and the cartridges slide quite easily fore and aft in the chambers (the owner had cleaned the chambers due to advice about switching to .357 after .38 Spl.).

The .357 cartridges would slide back against the frame when the revolver was tilted up.

Question: Is there a problem if the cartridge is free to slide back and forth in this manner? I realize that the firing pin strike on the primer will knock the cartridge forward upon impact, but what happens after that?

This may only be a problem with a clean chamber, and a few rounds of residue will most likely change the situation.

As always, thank you for sharing your knowledge with me.
