Just got in a case of Remmy 260gr Accu-Tips, and this batch is not going to win any awards for good looks. Most cases and bullet jackets have cosmetic "stain" issues. It looks like some sort of liquid got splashed on the majority of the rounds. I'm not overly concerned about it, at this point. HOWEVER: I took my spectacles off, and...
Using my 20/400+, x-ray nearsighted eyeball comparator devices, I did notice something about these rounds that is puzzling and/or concerning. Looking very closely, I can see that the case mouths have three different configurations randomly distributed through the lot. One bunch has the usual slight crimp inwards toward the bullet jacket. Another bunch doesn't seem to be crimped at all, with the case mouth perfectly straight "ahead". The third variation has the case mouth very slightly expanded outward, away from the boolit, like it just barely got bumped by an expander plug. Below the area of the case mouth, they are all straight, no bulging or anything unusual, other than the previously noted scratches and dents on some.
Anyone else noticed these case mouth variations? I'm going to sort them by "design" and see if there's any difference noticeable at the range (fps, groups, etc.), what with neck tension being a tad important to this caliber.
(The Hornadys I have all seem to look identical, including the microscopic ring along the top edge of the case mouth...?)
