As I recall, the instruction for my 45 Auto resizing die call for it to be adjusted so the shell holder doesn't quiiiite touch the bottom of the die. Even remember grinding down the top of one shell holder so the cases went up a little farther into the die. Doing so insures the case is given as much of full-length resizing as is possible. But this raises these questions:
• Is it important for 45 Auto cases to be full-length resized?
• What happens if they're not full-length resized?
• Could they get shorter?
Don't know the answer to any of those. All I know for sure is I've never seen cases like the ones in your photo. And I've been reloading them for <gulp> 55 years. They almost look belted!
Maybe somebody else has the answers.
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. [Lord Kelvin]
