Re: Forming 9.5 x 57 brass...

Hi Waidmannsheil,
If you expand the neck over size, and then size the neck back down until the case just chambers, that will form a false shoulder to headspace on.

This is as I explained above by necking straight- then to a crush fit.
When using new 8mm brass, I lost no (zero) cases, when running 8mm out straight (or .30/06 or .35 Whelen) - that is, from 8mm to .43 in the .44 mag expander, & 8mm to .45 with the expander I turned. 1 pass - 0 losses.
When I opened up just over 150 old .30/06 brass, including some .270's, I lost 7 cases to split necks - out of over 150 old cases. Some of that brass had been loaded over 5 times. After forming them to chamber in my rifle, I annealed the old brass before continuing to load them.
