[QUOTE="MagnumManiac, post: 1290469, member: 10755"] Trim to the shortest case AFTER the first firing. Trimming before fire forming causes necks to lengthen unevenly. You most often find that the first firing is where the brass lengthens the most, then settles down somewhat. The actual length, if short, does not pose a problem in regard to function, unless you are crimping the bullets. In this case, you will need to trim them all the same. Longer than the max length can cause very serious excessive pressure issues. Cheers. gun) [/QUOTE]
