If weighing charges is not an issue, nothing beats Varget!
No temperature sensitivity! It works great across the
bullet wt spectrum of the 223!
TAC runs like water through a powder measure, and it seems to fairly temperature insensitive, but no where near Varget.
N133 for lt. wt bullets is pretty good deal!
Benchmark is not a bad choice.
748 is very temperature sensitive, and I think it is worth staying away from if you are loading for PD hunting!
