Anybody use a Case Pro roll sizer with .223 plates to resize their brass?

Just like the title says....

 

on another forum, there is a discussion on annealing brass.

 

some guys say their brass's primer pockets get too loose before the necks start splitting.

 

I am just wondering if Case Pro'ing .223 brass would extend the life either putting off the split necks or keeping the primer pockets tighter???

It would have no effect on either. The necks split because the brass becomes too brittle, thus annealing softens is back up. The primer pocket opens up because too much pressure is trying to leave back out the flash hole.

Okay....

 

I could swear I read here years ago that the .38 Super guys were roll sizing their brass with hopes of keeping primer pockets tight.

 

I was also thinking that NOT having to pull the case mouth over the expander ball of a normal or convential full length resizing die would mean less work hardening of the mouth/neck.
