I finally got all of the supplies I needed for case prep and reloading purchased, which was tedious because I had to go to several locations to get it all. Anyway, I have three different kinds of once fired .308 brass on hand-and in cleaning I noticed varying differences in their size and how they formed to the chamber. The Magtech and Federal didn't deform at all, I couldn't find any bulges at the base. The Winchesters all expanded a bit about 1/8th inch above the base. So it appears that Winchester brass is smaller than the spec's of the rifle for some reason. Has anyone else noticed this with Winchester brass?
