I experienced serious setback from both DT, and BB .357 sig ammo. I even tried pulling the bullets and re-crimping them, but they kept "falling" into the brass. I could even apply finger pressure to a few of the rounds.
Winchester White Box....not the same issue, but I wouldn't want to use it for self defense.
Will post a few pics tonight.
