[QUOTE="El Matavenados, post: 1462184, member: 89192"] Today I fireformed 10 ADG cases in my 338 SS. Case lengths after necking from 7mm to .338 but before fireforming were between 1.939" and 1.945". 7 of them were between 1.940" and 1.942" I loaded them with 60 grains or RL 22 behind a 225 grain Hornady interlock jammed into the lands, as this did a good job forming Norma brass. I did not do any neck reaming or turning prior to fireforming. After firing, the bolt lift was much heavier than I expected, based on my experiences with Norma brass. However, there were no pressure signs. Primers looked fine, no ejector swipes, nothing unusual other than the heavy bolt lift. Lengths after fireforming were between 1.931" and 1.937". 5 were between 1.933" and 1.935". Next Saturday I hope to get the necks trimmed and turned, and get some real test loads sent down range.
