That got the attention of some of you

8x58RD can be made from belted magnums, thats right range pick up!

Start by removing the expander ball.
Pic 1+2: Run the lubed case as far in the FL die as it will go (i used a 300WM).
Pic 3: Turn the base down to 0.50"
Pic 4: Run through the FL sizer again to get the right length.
Pic 5: Trim to 58mm~2.28" and here is the finished product before tumbling.

The rim ends up on the small side but it extraxts positivly in both my Swedish rolling block and Danish K-J.
