[QUOTE="MagnumManiac, post: 1654478, member: 10755"] I form using COW (Cream of Wheat), a fast pistol/shotgun powder and a plug of TP (Toilet Paper). The formula I use is take the average volume of the case with a max load with NORMAL powder, reduce that charge 90% and start loading with that charge of Universal or Clays, load case, place paper wad over powder, fill to just below the neck with COW and twist the TP into the neck to fill and seal it. Most often, the TP is tight enough when it squeaks a little as you poke it in with a pencil. Keep increasing the powder by .5gr increments until the cases are fully formed, but NOT SHARPLY formed. Trust me, you can have a pressure excursion when fireforming, I know, I've done it. Just go slowly, and stop when all the case is formed, at the lower charge weights, you may find the the lower third of the case doesn't form at all. If this happens, put then aside and fireform with a load that gets the other cases fully formed. Hope this helps. Cheers. [/QUOTE]
