	I always blew out shoulder the way John does, and it's perfect. I have also shot factory ammo in one chamber, a .270 imp, and it not only formed 'em up, but shot very nice groups too. Go figger.

	I've done several methods. Might depend some on the shape. It certainly depends on soft enough brass. I just finished 150 rds of 30-30 neck sized to 7mm and blew out with cast bullet (132gr GC) and 6 grains of Unique. Only lost one, but it had a crack in the edge of the neck anyway. All were annealed prior to shooting. OTHERS, have NEEDED a filler.

	I've occasionally had great luck with a load close to what I'm going to fire in subsequent loads, during case forming. The .40-85 Ballard loads I fired last week were fire formed from 9.3x74R and over half of the cases were not fire formed yet, but shot as well as those I'd previously fire formed. Some cases I do use fillers and no bullet, but some I simply fire with a bullet and charge I like. Depends on how much the case needs to move during fire forming.
