[QUOTE="J E Custom, post: 1874458, member: 2736"] I would recommend that brass should be trimmed a minimum of .010 thousandths shorter that your chamber, and a maximum of .030 shorter than the chamber. Sammi gives you the recommended trim length of SAMMI cartridges but that doesn't mean that your chamber is that length, so first measure the chamber length for case length and decide where you want to be and trim. Some case designs grow in length each time they are fired so in those cases .015 would be a good start, Remember, the bigger the gap between the case and the the actual chamber the better chances of carbon build up so keep an eye on those case lengths that are near to the chamber dimension to prevent problems later.
