[QUOTE="Saskquatch6, post: 2161574, member: 58704"] Brought out some older Lapua brass - 4x fired 6.5x55AI - can't remember when it was last used, but likely 5-7 years ago. Its in good shape, primer pockets tight etc - but when I measured case length thinking I may have to trim, I found it all to be around 2.135" with some shorter at 2.127". Specified trim length is 2.155" (max is 2.165"). Checked the Lapua brass I'm currently using (not resized) 3x fired and its length is 2.147" - still short but at least close(er) to min. Checked trimmer pilot and it measured 2.163" (actually a bit long vs trim length). This brass was purchased new and fired only in this rifle. Two questions 1) In your experience is it typical to end up with shorter case necks in this range when FF cases to AI? Would you use these FF cases with necks about .020" shorter than min specified trim length and potential issues/dangers of doing so? PS- my usual case prep procedure would be to trim all new brass to same specified "trim" length then size, load, FF etc. [/QUOTE]
