In the tests posted by LuckyGunnerLabs they showed the Tula they used had velocities that were nearly as high as the Winchester brass they were also testing.  It was higher than the other two types of steel cased ammo they were also testing.  However the other two types of steel did not cause the issues they witnessed with the Tula.   With Tula ammo the issue is not of being underpowered but one of improper burn rate of the powder being used.  Since the AR uses gas pressures to operate the gun there are "Timing" issues that must be taken into account.  Powder burn rates not only affect pressure but also the pressure curve after the round is fired.
Sometimes the symptoms caused by this ammo make it appear to be underpowered however in reality that is not the case.  Because of the pressure curve of the powder used the carrier is trying to extract the fired case too early in the cycle.  To early and the case is still under expansion from the firing which causes the case to be too hard to be pulled from the chamber.  This will either cause cases to remain in the chamber or enough resistance to cause the carrier to possibly not have enough force for the extraction sequence and appear to be short cycling due to gas issues.

In other words you can't just use any powder in a 223 round and expect it to work properly.   Some guns for whatever reason will work okay using this ammo and others not so much.  Probably due to parts tolerances more than anything.  I would imagine barrel gas port sizes have a lot to do with it as well.

ETA:  Oh and bullet POI changes probably have more to do with barrel harmonics(caused by different charges) over simple velocity changes.

My RRA's will not eat steel. I shot about 20 rounds of it back during the first panic. Shoot only brass.

My BCM 14.5 upper eats wolf like candy.which is odd it has a stt2 buffer which should be a recipe to fail.

Goodluck maybe try cleaning The chamber and run some good lube and try again.
What buffer/lube you running?

Used up all of my WPA.  Finally over.  I am never, ever going to purchase Wolf products again.  They suck.  They could not hit my targets at 100 yds.  I would say maybe 3 out of 10 would hit the mark.  It's as if they come out drunk on vodka.  And they would just fly anywhere.  After finishing off the WPA, I went to brass.  Boy, they were load as compared to WPA.  And they hit their mark.
