Mate,
Please understand that you started the thread asking us to go to some effort. Where I am coming from is that if we are going to do this then let's at least make it worthwhile, for all of us. What seems to have occurred is you wrote a cheque your experience can't cash and have thrown down your toys when someone asked you to explain. You are not entitled to this (private) information, nor are you entitled to our effort. When you ask for something expect that we will get interested and want to get involved - ask what it is for. The cost for something you are not entitled to is that you need to explain yourself... without getting upset.
Now, I have given you my COAL's for 10 bullets. This is my private data and represents effort. I would be grateful if you do the same. Note how in every case the magazine is the limiting factor where jump is concerned. The one that is closest to the lands is the Hornady 95gn which is a short stubby bullet, but even at mag length there is only 4mm of shank in contact with the case neck. Neck tension is now an issue, especially in auto loaders.
Here's my data again with an extra column for the amount of bullet in contact with the case, when seated to max mag length. Anything less than the diameter of the calibre (6.5mm), especially in an auto loader is cause for concern. If you can't crimp to make up the neck-tension difference then I worry that the bullet might shift before firing. So the two lightest rounds with 4mm of contact will need to be seated deeper, which means more jump. I think neck tension is more important than jump in this case so it's the lesser of two evils.
Back to the original request for bullet seating against the lands info - It's all moot in my gun. It's either mag limit or even less... What about yours?
