I'm down to my last 8 lb jug of WC846 (out of 4) and have used it for several different cases. Most of it has been with 223s. Have used 26 grs with both 55 and 50 gr bullets for years. Nice accuracy and adequate velocity with no pressure issues, and both loads shot to the same POI.

Recently, a friend gifted me with an 8lb jug of Data Powder 2200. I loaded a few 50s and 55s with the max charges shown on the original data sheets that Accurate put out for the powder back in the 90s. They surprisingly shot to the same point of impact as the WC846 loads in my L46 Sako. Just for slaps and giggles, I shot one of each of the 4 loads as a group before leaving my range. There were no diamonds left without holes, so I used a corner of the big diamond as the aiming point. The result is shown below. This group was actually smaller than the individual groups...go figure:
