We seem to be seeing a fair few questions on reloading that the answer seems to be trim the case to the proper length.
This has got me wondering how many don't trim or don't even know that cases need to be trimmed.
One need not spend a small fortune of a trimmer as there are lots of ways to achieve the proper end result. From trim dies or the Lee Trim studs to the case prep stations.
However it's done it's something that must be kept in check.
