Thanks that’s what’s needed to see. Guess I should explain “back side “ for those not familiar with Ponsness Warren machines.
375 head has die mounting holes all around the round head. Enough for one set on the front, another set in reserve on the back. To switch gages take the head off & reverse, front set becomes the reserve, back set moved to the front becomes the active loading set. No need to re-adjust dies. You do have to switch the bottom shell holder out for the new gauge. Wad Guide needs to be gauge switched too.
I should add PW had 2 types of sizing dies. Older type are full finished crimped shell length for 2 3/4 inch, they won’t allow crimping 2 1/2 inch. New type “taper crimp” is shorter allowing the new style knock out station to put a little taper on the finished hull. One in your photo looks very much like a taper crimp. Or they may have 3 lengths now.
Think I will go ahead and order a Short 10 die & experiment with my 12 G set up machine.,
William
