BC,
I' ve been using Black Hills in my 223. They are loaded with the Hornady V-Max. They' re terrific for ground hog. They work really well for turkey also. I' ve tried many other factory loads in my 223, but mine seems to like the BH the best. My best group being .566" (five shot @ 100 yds.) I' ve never tried BH in any of my other calibers but if it works for you, go for it.
