I really like the Corbon 275 gr. and 325 gr. but, besides price, availability here in the south is terrible.
I started plinking with the Hornady 200s because of price and availability and, lo and behold, my groups tightened. So I decided to field test the 200 gr. on an Illinois nanny and, lo and behold (again), drop city!
I'm sticking with the Hornady 200, even for Wyoming mulies this fall, until something better (than Hornady)--and more economical (than Corbon)--comes along.
