If so, then sounds like the 1:11” twist is not fast enough to stabilise the longer 200gr bullet.
@shooternz’s 151gr bullets are specifically designed for .308.

Yes, is a 308, my barrel was pretty filthy after that, wasn't that clean to begin with.
I had a bag of the 151gr too but started with the 200gr going with the theory of bigger is better.
Used a standard primer and copied @Flyblown and loaded up some 151gr with 7.8gr of trailboss and had a chance to put them on paper and over the chronograph today and am happy with the results.
Will have another crack at loading the 200gr in the future
