Ok, have now fireformed 20 brass or so, so I'll report.
Its going well, in between sleeping and working 12 hour shifts I'll load 5 and go out and shoot.
only precaution I have to give is, remember the feel of the bolt going closed, the burnt COW sometimes is left in the neck and smears the next brass upon firing, so about every third round I run a nylon brush through the barrel.
The shoulders just show a hint of being rounded but they will be fine.
