Well I haven’t actually slugged the bore and I’m assuming that’s what you meant when you asked what it miked at. That’s on the agenda for today if I can find some pure lead egg sinkers in my fishing stash. Haven’t used any of them in a long time but I’m sure I had some somewhere.
I’ve ordered a Lee .452 sizer die for these bullets as they’re crowding .453 unless you really snug the mike down tight. I may be making a mountain of a mole hill but then getting there is half the fun right?


Good judgment comes from experience, and most of that comes from bad judgement! 🥴
