I use Winchester White Box, sometimes as a practice load and mixed as my carry loads in .40 (180 grain FMJ/JHP), and my .45ACP (230 grain JHP).
It is an excellent performer from my perspective of shooting. Even better, it's readily available and inexpensive enough to rotate with my carry ammunition frequently.
I've carried the "premium" stuff, and while it's nice to have a fancy name on the box...the White Box gets the job done just as well and will "kill" just as proficiently.
