Over bulleting?
Maybe its using cup and core bullet 50-150 grs. more and jumping up calibers to do the work a little mono does with less powder, more velocity is the definition of "over bulleting".
I ddn't state my question well enough, but basically in .308 going from 165gr. C&C's to similar weight mono's and seeing them used primarily for much larger critters. the suggstions in this thread to go down in weight and up in velicity with the mono's is golden. I'm gonna do that just gotta find a load
