I was loading some 308s last night and was sizing the cases and placing them in a block awaiting powder and bullets, when I noticed light shining through several of the necks (I had a light on my bench behind loading block).
I would have caught this even if I hadn't seen the light as I inspect and feel of each finished round. My question is what would happen if the round had been fired? I suspect that the split may have been sealed with the bullet IF the split was not a large split. Would the case neck collapse on the brass with larger splits? The brass had been reloaded ~ a dozen times. Guess it is time to buy some new brass. |

Wow, 12 loads on brass; that's doing well. I can only get 4-5 but it's in a semi auto.
You will run a risk on some gas cutting on the chamber, I would scrap them myself, I doubt that you would have had any major problems, but one should be safe frist off. sdshooter...................... |

Generally it'll fire fine and it's not a safety issue, like a case head separation. I've often thought about loading up cases with splits in the middle of the neck and not out to the edge, but life's too short and I do keep spares. You're dealing with just the grip of the bullet and it theory, tension could be broken with a full neck split, to some degree, so the release might be different from that case to the rest. Benchrest shooters love to soft seat their bullets, seating them long but loose. When chambered, the bullet hits the lands and self-seats itself. I bring this up because tight tension isn't something that has to be present, although unchambering a softly seated bullet will allow the powder to spill out if the muzzle isn't pointed upwards. The split neck will expand and then retract, just not as tightly. Chris |
