I'll go over the slugs again today.....
It would not be out of the question that I've got things backwards....
Bottom line: There is an issue.....
If the holiday were caused by something at, or on, the angle of the leade, most likely when the slug was pushed into the bore proper, the depth of the land cuts in the bullet and the reduced diameter of the bore would wash the holiday away.
Now, this from memory:
Seems like the slugs pushed completely through the bore exhibited this holiday, too....
Although don't 100% hold me to that..........
I'll review the slugs and post something later....
Your friend, BC

The ratchet is yet to come......
Here's something for you to ponder before we start with the ratchet:
When one views the bullet from a live round that has been pushed into an "as reamed" chamber, not finished yet..
Or an "as bored" chamber, also....
The angle of the leade has a "signature" that is distinct for each style of rifling...
The ratchet's signature is most distinctive, and unique, since the driving side of the lands are vertical, while the following sides are angled..........
I guarantee J-PAT knows exactly what I'm talking about, since we've spent a bunch of time analyzing the different rifling pattern signatures...
Anyway, keep this in mind when we start discussing your ratchet.....bc
Bill,
I don't see anything like your pic on the left hand side of any of the lands. I did a quick mod on your drawing and what I see is this looking in at the nose of the bullet:
The right side of the land is angled up and away from the bottom of the land groove. But this angle does not run true down the length of the groove. It is more pronounced at the front of the driving band. At the rear of the groove, things look pretty normal.
I sort of can't see how this can be. I drove the slug in 4". You would think that if there was a defect in the barrel somewhere, that this angled look would have gone all the way down the length of the land groove. Unless I somehow manged to stop the slug right at the place where this thing - whatever it is - is situated and I just caught the front of the slug with it. Seems unlikely but I'll drive one in 6" and back it out and see what gives.
It's probably some sort of optical illusion but it sure looks like a real thing.
