[QUOTE="Pdvdh, post: 1403646, member: 4191"] Pictures of the Lake City .223 case head. Turned the belt-less case into a belted case. The case rim flowed to the point of shearing outward where the extractor slot is present in the ring of steel at the bolt face, which surrounds the case rim. The case rim also flowed back into, and laterally outward, into the void where the plunger hole exists in the bolt face. The flash hole enlarged to twice normal diameter. The brass case rim and case head flowed into all voids where they weren't supported by the steel in the recessed bolt face, or by the steel chamber. This was a 55gr Nosler Varmageddon bullet, by the way. Flat base bullet with the plastic tip. Fortunately, there wasn't any torching away of the bolt face, extractor, plunger, or anything else. Never knew anything was wrong until tried to open the bolt. It was supposed to be a reduced load that would barely cycle the bolt open. So I thought the bolt hadn't opened and the casing hadn't ejected. Wrong... Don't think there's any salvaging this casing for another loading. o_O [ATTACH=full]90831[/ATTACH] [ATTACH=full]90834[/ATTACH] [ATTACH=full]90832[/ATTACH] [ATTACH=full]90833[/ATTACH] [ATTACH=full]90835[/ATTACH] [/QUOTE]
