Many of those steel based shells are like that. Steel expands on firing and stays put whereas brass expands and then contracts to a certain degree. So, the steel based hulls have more tendency to stick, esp in guns with tight chambers, as opposed to brass based shells. I reminisce about the good old days where real brass based hulls was all you got. Seems like the only premium competition shells with brass nowadays are Remington STS and Winchester AA. Federal just puked out going from brass to steel. Lets hope Win and Rem dont.
