okay, at least im ahead of the game here. i have 40 .40 s&W rounds loaded. one of which lacks almost all the powder. i had my son helping me and he spilled one of the casings, didnt inform me, and loaded the bullet. i saw the pile of powder near the end of the 50 rounds. so the last 10 i did and set aside. so that leaves me with 40 rounds. i measured the powder and it was almost exactly my charge weight. so like i said at least i know i have a dud. but now how to find it. i really dont want to lose all 40 bullets. the casings powder an primers are cheap enough but my hornady bullets are not. lol i dont have a bullet puller, as of yet i tried to weigh a couple other rounds i knew were loaded correctly. i assume due to brass sizing, the difference in weight between 2 100 percent good rounds was well over my charge weight. leaving me to think weighing them all still might not be correct. thought about shooting 1 at a time and if the bullet got stuck in the barrel get it out that way. but im not fond of that idea. any thoughts? do i need to suck it up and buy a bullet puller? if so, which one?
