I have a Lee press, I do not use it but I have one just in case. Meaning I understand press flex and deflection on all the presses I have. If the case has more resistance to sizing than my press can overcome the case does not get returned to minimum length/full length sized.
And then there are all of those methods and techniques used to overcome the case's ability to resist sizing, and then, there is the discipline involved in determining how much deflection/flex the press is going through. I use the companion tool to the press, the feeler gage when determining the winner, the case or the press.
Some extractors have a hard time getting over the rim when the round is placed in the chamber, then the bold closed on it. Its possible to even set the shoulder back a few thousandths. New brass is undersize enough already. Headspace should not cause misfires with a Savage .
You guys are at a disadvantage. You have case head space and chamber head space; my cases do not have head space and I do not assume the extractor is jumping the case rim.
But there was this reloader that kept sizing the case until the bolt closed. 'AND THEN' he had case head separation, his rifle was a push feed and he assumed the extractor was jumping the rim. AND THEN, he argued, he claimed the case head extracted, it was about that time I was out of breath and said 'FANTASTIC".
