I haven't found any that were really bad, but I don't shoot steel cased .308 out of my rifles. Or, at least I haven't yet.
What type of rifle? And what type of expectations do you place on the ammo. If it's a semi-auto: do you want just good function, cleanliness from powder residue, accuracy standards? If it's a bolt gun, I imagine accuracy is what you are after.
My auto loader is an M1A and it is mostly fed a diet of military surplus ammo along with some match ammo. I've used German surplus, Portuguese surplus, lots of lake Ciyy Ball and match, along with Federal Gold Medal Match. My bolt gun is a Savage 10. It will eat anything but it seems to like bullets in the 165-180 gr range the best. It gets mostly handloads from some of the brass from the M1A.
That which does not kill you makes you stronger...except submarines, they'll just plain kill you.
