Has anyone ever made 6.5x55 brass from .30-06 brass? I am in the process of having built a 6.5x55 on a 1909 Argentine M98 Mauser action. I have about 500 rounds of once fired .30-06 brass and no 6.5x55 brass. Redding makes a 6.5x55 form and trim die that takes the 06 brass to 6.5x55 in one pass. You then shorten the brass and then size in 6.5x55 FL die. The problem is that the 6.5x55 case is slightly larger at the head than the 30-06 brass. In researching this on line, opinions are about 50/50 as to whether this is a safe process or not. The boys say that the 06 brass will bulge slightly at the case head. Some say that you can load the brass 2 or 3 times and not experience any signs of case head separation, then discard it just to be safe. Others say don't try it at all. I do know it was once a common practice when 6.5x55 brass or ammo was not available in this country. Anyway, please share your experiences if you have done this conversion and what were the results.
