I was sitting in the reload shop this afternoon resizing a few 25-06 cases. My stepson had left me some of his 30-06 brass... well why not free brass! I had no issues stepping from 30 to 25. I chambered a re-sized empty with no primer and felt no resistance in the bolt. I am not doing this for any reason other than an experiment. I know this was the origin of the 25-06 as a wildcat back in the day, but does anyone know of anything extra that has to be done after full length sizing to use these cases?

Check for case length....trim if necessary and go shooting.

Like Vapodog said check for length. I would also make sure with the thicker neck I had enough neck clearance in my chamber

Paul's right about the neck thickness. 25-06 brass is thinner in the neck than the 30-06. I don't know who the genius is that figured that one out, but check and ream.

1. Anneal your new necks or they will split early.

2. Measure the diameter of a fired case and compair that to the diameter of a loaded (dummy) neck of your new cases. They will likely be fine but you HAVE TO KNOW, not guess. If the loaded diameter is smaller than the fired diameter you are good to go. If not, you will need to turn the necks to make them so.

Turning is preferable to reaming and there are lots of rational priced turners available these days. (I've tried several and settled on the Forster HOT-100.)
