Loaded 100 .430 diameter 250 grain SWCs yesterday. Using a Pacific powder measure, so I had to live with the powder weights the inserts dropped. Half are 7.3 grains of Unique, the other half are 14.8 grains of 2400. I'll report back once I get a chance to shoot them. I need to get the caliber conversion kit for the .44 Special from Dillon.
Thanks again to all of you who responded with data.
