[QUOTE="MagnumManiac, post: 1107247, member: 10755"] How are you fireforming? In your situation, you can safely fireform cases by using a medium/middle load for a standard 243, seat bullets to be into the rifling .005" and shoot, this will allow a complete fireform to YOUR CHAMBER, then only neck size until chambering becomes tight, then, once you set your bump at .002"-.003", bump from then on, because if you FL size, you will have to fireform again and start over. I would also advise you to anneal your necks prior to fireforming. If you want this issue fixed, you will have to take the barrel off, remove one or two threads and re-chamber with .005" negative headspace, which is how it should have been in the first place. On a side note, you can use a fast shotgun powder, Clays is perfect, it is bulky and a load that fills the case 2/3 with a twist TP over it and compressed slightly with a chop stick, should give a good fireform for your chamber without case stretching or split necks.
