I cast about a hundred of these in poor light as soon as dinner was done last night. I have a S&W 2nd Model HE with enormous cylinders and bore (4585) so I went with the 457 flavor. With the 3:1 WW-to-softlead alloy I had at the time in the pot, these drop at 4585-459 with a 775F melt.
Don't have a sizer in the right flavor; am going to double coat these in Lee Liquid Alox (LLA). Thoughts on Unique or Bullseye loads with Fiocci (small primer) brass?
Going to need all the help I can get with loads.
ETA: these are not the finest bullets I cast. Was getting dark on the back porch, and I see now I was swinging the sprue plate to early on the first 2-3 dozen after things got working well. I realize I should be using a 1:1 or softer alloy.
