The LEE 476/400 is a good bullet but I wish the rear driver was a tad thinner and slightly deeper grooves. You should melt those other things down for the alloy. Send me a PM when you get time. I have some I will send for you to play with. LBT 350WFN,400WFN,440WFN. See what Flavors you like.
Have a good one.
