Tatershooter, let's get down to some basics. First off, a quick glance at the primers of the rounds that were stuck in the cylinder would tell you if they had been fired or not, since the primers would have dents in them. Or a glance at the front of the cylinder would tell you if there were any bullets in the cartridges (doing so only when the cylinder is open, of course). The next thing to do is get the fired cartridges out of the moon clip and check to see how the moon clip alone fits in the cylinder (do this with all of your moon clips, in fact!) If any are difficult to remove they should be set aside and checked by someone who knows a bit about them. They may be slightly bent or maybe a little oversized, both of which can be fixed fairly easily. If all is working as intended, you should be able to punch the entire clip & spent cartridges out with one thumb. Hitting the ejector rod works if the cartridges are hard to eject but it should not be necessary every time the revolver is fired!
Generally, you want to avoid any steel (Wolf, Tulammo, etc.) or aluminum (some CCI) cased ammo and use only quality brass cased ammo, such as Federal, Speer, etc. The steel and aluminum cased ammo is cheap but these type of cases don't have the same slippery and expansion properties as brass. Whatever you use, make sure it is brass cased, and not plated or some alternative material.
If the ammo you have works in your Glock, even if it is steel or aluminum cased, there is no need to get rid of it, just keep it for your Glock and don't mix it up with ammo for the Ruger.
It is also possible that the chambers in the Ruger are just a bit too rough, in which case you can send it back to Ruger or have your gunsmith polish them a bit. This is not a difficult job, doesn't take long to do and shouldn't be overly expensive to have done.
Lastly, a bit (as in a very thin coating) of oil in the cylinders might help with extraction. Put some oil on a patch and run it thru the chambers in the cylinder, then run a dry patch thru them one time. This will prevent rust and should also help with extraction. However, too much oil in the chambers is NOT a good thing and may actually cause extra wear by not allowing the brass to "grab" onto the chamber walls as it is supposed to!
Just some starter info as you don't seem very familiar with revolvers.
Good luck & good shooting!
Cheers,
