I was loading Winchester 124 gn fmj bullets to a col of 1.125 These bullets measured from .589-.591 I bought some Precisio Delta 124 grain fmj. I measured a few of those, and they were between .603 and .607, so I settled on .605 and shot a couple hundred of them with a col also of 1.125 All shot just fine. I was using starting loads of powder. Then the other day while it was raining, I measured a bunch of the PD's, and the lengths ranged from .584 to .625. That seems like a huge difference to me. The weights weren't any higher than 124.5. This brings me to my question: If my bullets were the same weight, and I'm using starting loads with a col (1.125) which is way above minimum col (1.095), should there be a problem? I know I must have already shot some of the longer ones.......Thanks
