So I've seen this happen quite a few times. If you go to some of the competitions the guys will seat their bullets long and with light neck tension. If for some reason there is a cease fire and guys have to open their chamber with a round in the chamber they will sometimes get there bullet stuck like that. Makes a mess and you need a rod to push the bullet out of the lands. To me the easy fix would be a few things. First you need to make sure that your brass is the correct length. Are you messing with neck tension? If so you might want to add a bit more neck tension. I run about a thousand and a half of neck tension on my hunting rounds. You should also be using a full length sizing die when you size your brass. ALWAYS!!!!!!! Then look at where your bullet is seated. It is obviously seated to long. If it was shorter then it wouldn't be stuck in the lands. So seat the bullet deeper. Depending on bullet I run .010 to .050 off of the lands. Keep this in mind. You are developing a hunting round. This doesn't have to be the most accurate round but it does have to be 100% reliable. So full sized case that is the correct length, seat your bullet deeper to get off the lands, add a bit more neck tension, think perfect reliability not perfect accuracy.
