Well, if the barrel doesn't like 168gr SMKs, then the first place I'd check is the crown.

Flat base bullets can beat boat tails in accuracy because there is less bearing surface on the tail for off center gasses to push against. I'm assuming that the 150 gr bullets are flat base, could be a bad assumption on my part.

I'd try recrowning first.
