Dan, in general,, we will try & help answer any & all honest questions here. But,, we also need serious details too.
Since the ammo you mentioned is 3 different brands,, and all of it is used by many of us here,,, arfmel may have your answer.
LIGHT lubrication is all that's necessary as a metal protector against rusting. Wiping the exterior of the gun down after cleaning with an oil cloth, is all that's necessary. Serious lube goes onto moving parts such as internal action parts. And even then,, it's not to an excess.
Oils, greases, etc can & will hold dirt, grime & powder residue. so, wipe off all the excess prior to shooting. The key here is LIGHT coating of protectant.
Let us know how it does after your cleaning & all.
As for the Ruger Customer Service,,, not being party to the actual conversation,,, I can not say if they were good or not. Quite often,,, it's how a conversation goes & it MAY be that you hesitated, or felt that Armscor was the main ammo used & the CS rep THOUGHT that was all you used.
Or,, heck, we all have bad days or jump to conclusions at times.
In general,,, Ruger CS is quite good.
