I bought a thousand of the NCC 77's too, Sierras are impossible to get and the Hornady 75's aren't near as accurate.
Anyway I loaded the NCC's a few years ago and noticed they hit pressure before the Sierras but nothing serious, they just won't take the same max loads. I don't recall if I ever killed anything with the first box I tried but I know the Sierras kill coyotes very well. My guns liked the Sierras better but less than a 1/4" better.
I haven't loaded anything else in several years, I like the 77's.
I will add that ballistic gelatin tests show the Noslers to be slightly more frangible than the Sierras.
