Loading some *REAL 10mm HARD CAST

Using my Arsenal 403-200 WFN mold cast from pure 100% Virgin LINO TYPE lead. These bullets weigh in @ a lite, 185.5g. (200g weight is with softer COWW alloy)

Im loading them in Virgin Winchester Cases.

Using Alliant Power Pro Powder.

Sparked with CCI 300 LP primers.

Powder charge is not disclosed as I am beyond book but safe in my pistols loaded to my needed velocity. No appreciable pressure signs on my brass.
