Yes. I use 90 and 115 gr 6.8 SPC, 150 gr.308 and going to try some 123 gr in 7.62x39. From my personal experience, talking to other knowledgable hunters and seeing some of the ballistic gel tests on the Tube, Fusion bullets work very good.

I've found the factory ammo to be pretty accurate in most rifles, maybe not "sub MOA" but almost always hunting accurate.

I personally like buying the bullets as reloading components. I've found Speer provides good information for reloading their bullets.
