2230 seems to be off the radar for most shooters but I have shot 2 8# jugs at prairie dogs and think it is the best for my guns.
TAC was developed for the 308 but many people also use it in 223 .
Like the man says only your gun will tell you.
I have not tried 2230 in the 308 yet. I did find a 30-30 load I like.
