Article on shot missed the mark

The article states that low carbon shot is "interchangeable with other steel shot." This is not the case. Low carbon shot, due to its microstructure, is by nature softer than high carbon shot and therefore does not demonstrate as high a level of energy transfer. Lower energy transfer translates to slower and less thorough cleaning of the work piece. Typically, low carbon users must use one size larger than high carbon users, which means less coverage and slower cleaning rates.
