Hi Mongrel (and everybody else
), you seem to have your sizing problem resolved for now.
For future reference, I suggest buying one of these in the caliber you're loading for. It's a case gauge, with the correct dimensions for the case. In other words if you've set everything up right, and run the case through, it should drop easily into the gauge and sit inside as it is in the photo.
The other end is important as well, if the neck sits outside the end of the steel, then you should seriously look at trimming your cases. This can be another reason why the bolt won't close, as I found to my annoyance when my AR15 wouldn't go into battery because I as a beginner assumed that my cases were probably ok.
The case gauge is a very fast, easy way to check that your case has been formed properly and will chamber reliably.
I run all my cases through this way and very seldom have anything that won't chamber.
I had one the other day in 9mm, but that was because I obviously had missed it to begin with.
