Well to answer your question, you don't really know till you shoot it :grin: .
But you are right from all indication, the owners of the Bull Barrel 308 Handis, they are great shooters. I haven't purchased one, due to the shorter barrel, but that's another topic.
Just find the load it likes, some have done well with just the cheap Winchester Super-Xs. I do love the 308, it's so predictable. And truely a proven cartridge if there ever was one.
After barrel break in and a good cleaning/polishing, I am sure you will be happy with the end results.
