Forming 7mm TCU What am I doing wrong?
I have started reforming cases for my new 7mm TCU barrel and I am not sure if I am doing it correctly or not.
I have done both once fired and new brass.
I backed out the sizing die as recommended to start with so it just expands the case mouth and doesn't move the shoulder back at all and figured I would start here and then bring the full length resizer down till the action would close for proper fit.
Much to my surprise the first round I did with no adjustment on the full lenghth resizer and each one after that dropped in fine and action closed. In essence what I am ending up with is what ever shoulder is left after the neck is expanded up from .223 to 7mm..
Is this ok?
Thanks.. DonT :shock:
