Thread: Newby reloading question. Tight bolt cases

So long as they chamber and close there should be no problem firing them, essentially you would be fire forming them to your chamber. You could load those tighter ones down a bit for the reforming process. If you could get a RCBS Trim/Form die this will set the case back to factory specs. I have several dies for different calibers and a shell that won't fit the rifle are reformed to a perfect fit.
