I use WC846 in my 223s, and my favorite hunting load is 27.5 grains of it with a 50 grain VMax. It produces a chronographed 3325 from a 22 inch barrel. I also load the 55 grain VMax with 27 grains of WC846, and it will chronograph right at 3000 fps from an 18 inch AR. I have planned on trying some 40 grain VMaxs in one of my rifles, and if I do, I will try 28 grains of WC846. I did a lot of comparisons between the different kinds of powders I tried, chronograhing all loads and seeing how consistent they were. WC846 was the hands down winner, and that is why I like it so much.....in addition to the fact that I have a lot of it that was given to me. I do think it is a little dirtier burning than some powders, and I would clean my rifles a little more often with it.
