"BTW the C8 or C8A1 (14.5"bbl) goes below the fragmentation threshold at 95m (this is the 2700-2550 fps area) the C8SFW (with its 16" bbl) does this at 140m."
That link was a good read. I stand corrected, and will try and find the ref I read on that so I can see it in context, and see if I am blind or the ref bad.
Thanks for the info.
