S&W 500. Looking at bullet molds, sizer dies etc. Closest mold I see readily is 508, if you use WW's they may shrink a tiny bit, say 506/507. The sizer die available is for 501. a .005 or .006 swage is quite a bit,no?? What mold and sizers do some of you guys use? Also, who has shot sabots and 45 cal muzzle loading bullets through their 500 ?? What load and what results?
