I bought some new Winch brass for my .25-06 and found a couple that were around 2.82" long, (min spec per Sierra manual indicates min should be 2.840").. I don't think I would be too much in the wrong if I used these cases anyway for fireforming. Has anyone else had bad experience with Winch case sizes? And if using them would be any major problema? I did try to FL size them but no luck. thanks.
