jam vs jump test

[JFrank]

I guess the question is how many of you actually see a seating depth change of .005 make a 1'' change at 200Y? As seen in the picture. Is this common? ty Don

Don, I’ve posted this before but since it’s a decent example I saved it.
The first is 300 yards jumping Berger 108
The second is VT 103 jamming beyond touch at 500 yards,
Note that there isn’t a drastic change in point of impact, only the shape changes .

I see the kind of difference consistent with what this sort of test always reveals
