For quite a few years WC-820 was my favorite powder in .357 and .44 Mag's. Then the surplus powder market dried up and WC-820 became very difficult to find. I then went to Alliant 2400 and H-110. This caused my reloading costs to go up a little and I didn't get the performance I was looking for. I missed my WC-820. Low and behold .... today I found 24 pounds of WC-820 and it all came home with me. I'm going to give it a good work out in my 454 Casull along with my .357's and 44's. I figure 24 pounds should last me a few years.
