Thread: Hornady ECX

The ecx is just a blunt CX designed to function in some traditional chamberings that har big blunt bullets. It requires speed like most other monos and in all honesty what they consider opened up is pretty weak. I'd say best performance comes from the impact speed with monos more so than weight so the 125s are probably a good bet as the 308 should sling em quick. There are monos designed for slower impacts speeds and open up well (almost all are designed for the 300blk like the tactx or 110cx etc) but still don't kill as well as a faster mono typically. Monos don't kill as well as lead and cost more I'd ask why spend the extra.
