Keep guessing my angry old rube.
In any case, play on words intended (like many things I know you won't get that -- just move on), the Ruger 30 owners manual you don't have and wouldn't read or understand if you did apparently, says to use U.S., i.e. brass, ammo. And for a reason. They are so much less reliable with steel ammo to the extent that the point had to be made to customers.
I couldn't care what bad things happen to you now CA357 and, heaven forgive me, I actually hope they do, but there are other readers here who are decent folk.
