The Powder Room - CAS reloading / Re: Round nosed bullets in a tubular magazine?

You'll find that when the next cartridge to feed to the lifter is stopped by the link, that it sits very straight in the magazine tube. The magazine spring pushes on that bullet nose and it normally straightens up relative to the magazine axis after "bottoming out". Most won't know this unless they have worked on the '92s and '94s and/or had to write up a Design and Function explanation as part of their training. That cartridge could easily be nose to center of the tail on the cartridge in front of it. The rest do sit helter skelter especially with bottle neck cases. There are cutaway rifles with a slotted magazine tube used for training and understanding the workings and you can see that jumble of noses up and down or left and right beyond the first shell against the link.
I've read the discussions about the older cases having "rifle depth" pockets, the truth of the matter is that there was NOT a standardized primer to begin with, Everyone made or had their design made. I knew someone who dissected a lot of shells and the primer thicknesses were all over the place. They were being used in low pressure Black Powder shells and you could get away with almost any thickness. Plus a lot of them were copper instead of the brass alloys used later. Balloon head cases, primers all over the map, it wasn't until the 20th century it really stabilized.
