I haven't had any issues with the steel cased ammo.

I didn't test the wolf ammo yet, but these are the velocity numbers i got from a 14.5" Faxon gunner match series barrel, 223 Wylde, shooting Red Army Standard:
SNIP

The 16" barreled upper has had at least 6,000 rounds through it at the time of testing.  I'm not sure if this makes a difference at all.

I was using a Caldwell chronograph set up at 10 feet from muzzle at Koko Head.  As you can see, the RAS isn't really "under powered" as much as a lot of people claim.  Velocity numbers are still decently close to m193 out of a 16" barrel

No experience with .223 Rem RAS ammo, but Tula 55 gr is advertised at 3241 fps.  I've shot a bunch of both 55 gr and 62 gr and they seem to be pretty weak ammo.  Or at least they didn't function well in my mid-length gas guns.  That was way back when I had heavier springs and buffers, which I have gone away from.  Didn't try Tula in carbine gas guns that I owned, at least at that time. 

In recent experience, I have some Rem UMC .223 bulk packs that seemed to be underpowered.  Not quite as bad as Tula, but did have some issues with at least one mid-length gas gun.  Shot the same ammo in a few carbine gas guns and no problems.  Interestingly, I've heard many folks say the same for PMC Bronze, but that ammo has been (or at least when I had more of it) awesome for classes and training.

i think the perceived "weakness" of the ammo could be a difference in the burn rate of the powder that they use.

As a wise friend once told me:

Faster-burning powders create peak pressure, sooner, but drop off very quickly, as well. Slower-burning powders take slightly longer to create peak pressure, but sustain pressure for a greater period of time. Both are bell curves, with more "energy" under the curve created by slower powder. So, all other things being equal, and presuming the powder in question is actually suitable for the cartridge being fired, slower powders WILL create more velocity...they exert "pressure" on the base of the bullet, longer.

I mean I took calculus in HS and college, don't want to deal with integrals when I'm shooting.  Haha.  Nah.  Maybe one day I'll grow up and mature into a hand loader.   

When it goes pew, I go whew, when it goes click, I feel sick.
