Has anyone used IMR 4166 with 55gr or 60gr bullets in the .223 ? I would like to try it but , I don't want to waste my time if it won't work .
 
Yes it works. Very clean burning and little to no copper fouling in the barrel. I’ve shot about 8 pounds of it at prairie dogs.

Only down side is that you don’t get top velocities and it fills the case up.

Yup, a real yawner in the 223. Plus the price is silly.
