I've dabbled with meplat uniforming (MCR Tool) on a 100 or so 300grn SMK's. They sure look good afterward
I scrapped my 338 before I was able to test them on anything fuzzy. Expansion should be a little more prevalent with the the meplats trimmed as the hollow point is a little larger.
Pointing is a different bag, pointing does tend to increase BC by quite a bit however, I cringe when I think of the terminal ballistics a FMJ would offer in a hunting scenario.
