The Pac Nor super match barrels are good barrels but I would probably lean toward a Lilja, Krieger or Hart simply because I use so many of these barrels and they always come through with flying colors. I probably use Lilja barrels on 80% of my 338 caliber rifles for customers and simply put, they all shoot and shoot **** well if installed correctly.
It really comes down to installation, have it put on right and any barrel from the top barrel makers will give you what you want.
I prefer the 225 gr Accubond over the TTSX just because it seems to have more reliable terminal performance over a wider range of impact velocity then the barnes bullets. That said, if the rifle like the barnes, by all means.
