I have the die set so that the new formed cases are about .001" less than the fired cases. It fits the chamber fine.
I have been using H4198 and H110 to fire-form with a middle charge weight.
I understand what you are saying about getting the case as close to chamber dimensions before fire-forming. I wish they would of explained this with the forming dies.
I will have to wait for the weather to clear before out again.
Thanks again,
Ray

You have it under control now. Happy shooting.
again, my favorite case is the 280 Remington, it has a lot of versatility because the shoulder is forward of the 30/06 by .051 thousands, because the 280 cases are available there is no excuse to fire a 30/06, 270 8/06, 338/06 etc with head space issues, cases can be formed for any of the above chambers by forming first then firing.
As to why they omit explaining the versatility of the case forming dies, I do not know, I apply the same rules to sizing cases with the full length sizer die, that makes the full length sizer die the most versatile die I have.

" Case forming dies usually need to be made to smaller internal dimensions to compensate for more spring back, because the case dimensions are being altered to a greater degree. Different brands, different specification i would guess"
Form first then fire. I have case forming dies, after forming I do not have a chamber the case will fit because the forming die is designed to form the shoulder at a more shallow angle to prevent the shoulder from folding AND the case tapper is less than the tapper on the full length sizer tapper, so the dimensions of the forming die are larger than the dimensions of the full length sizer die. And the shoulder is too far forward when formed.
And the instruction read something like: After forming the case must be full length sized before the process is complete.
And I believe the most over used phrase in reloading is 'spring back', when fired the case shrinks, when sized the case pops back out?? I give zero thought to case recovery, memory and spring back 'in' or 'out'. Spring back is not the bugger bear.
