Okay have an issue, used my Kac buffer today 100 rounds of wolf gold then the bolt started to not lock back and also started to fail putting a round in the chamber, it would go bang and click so I'd have to rack it back.

With Wolf Gold?? That's full power 556 ammo.
Did you have the KAC H2 buffer in? I don't mean this to sound condescending, but did you clean and lube the gun before shooting?
My 14.5 mod 2 with KAC H2 buffer ran fine. I did shoot a box (150 rounds) of Lake City M855 5.56 first. After that I shot a few boxes of Wold Gold, it couldn't be too much more than 100 rds if that. I did have one stove pipe with the Wolf Gold, but couldn't repeat it. It's hard to say whether it was ammo, mag, or gun related but I'm not worried about it.

Wait a minute, you replaced an A5H2 with a carbine action H2 and expected improved function? That would be a rare event.
Make sure you cover the basics first, then go from there.
Something to think about though is that the KAC doesn't necessarily need domestic LC like ammo to run, but it can run that better than others. If you want to run some other ammo, a 6920 could be a starting point.
Some ammunition has the potential to run better with the increase in time duration of the applied gas port pressure, some do not.
My personal preference is to feed the base system with ammo that works well, no matter what the base platform is. If your ammo selection runs better with brand "X" than "Y", but all you want to buy is "Y", then buy a base system that suits that better. If you buy brand "X", then buy a system that suits its potential.
The a5h2 bufferweights about ~5.3oz and the Kac buffer weights ~4.6oz. I ran about 300 rounds of xm193 when I first fired it, then I had a good deal on 1k wolf gold which a lot of KAC owners said theirs ran fine.if I have to run xm193 all the time that's fine with me but with others having great success with wolf gold I figured i would I've it a shot.

Wolf gold I have is 223

What would make you think that an import ammo repackager is as consistent as domestic LC 5.56 offerings? Have you looked at the suppliers for Wolf? How could they possibly bring a consistent product to market? With so many variables, it does not seem that that it could be feasible overall, just too many variables.
With most import ammunition, I've found that I do not trust the peak pressure ratings for .223 or 5.56. They could be okay, or maybe not, it's a roll of the dice. Port pressures can be all over the place. Some can work well, others not, just depends on the mix of parts.
What's a few cents extra per round in the grand scheme of things? I tend to caution folks who find ammunition for "a deal", if it worked so great, it would not be that cheap. Normally it is cheap because nobody else will buy it, for good reasons. Simply part of supply and demand.
It may be 223 but it's not weak like pmc bronze. Closer to xm193
