i did something really stupid last week, after i powdercoated 4-500 9x19s i grabbed a handful of them and used the calipers, the biggest one i measured was 358 but most were 357, so i skipped sizing
went to the range to test these things out and it went really bad, every 5-6 rounds i would have to pound one out of the barrel because it was 360 or more, so now i get to spend all day pullingh apart hundreds of rounds and sizing
luckily, i discover that to get the bullet out, all i need to do is run the completed round through the re-sizing die with the decapper removed and the bullet slides right out, thank god i didnt crimp
so long story short, if you PC you need to size
