For those of you that had no problems with the bolts, prior to the "boiling" fix:
2. Barrel bore diameter. .691 (Stock E-Mag w/plastic Nubbins)
3. Range of temperatures you have used it in. 40-70 D.F.
4. Average velocity you use it at. 260-295fps
Mine did not break. It was .015" oversized, and I sanded it to the proper length. My bolt broke paint like crazy, before and after shortening the length. You folks (AGD) have had the bolt since Jan 2.
