[QUOTE="QuietTexan, post: 2596074, member: 116181"] Ah makes sense. I wouldn't be concerned until you're at less than half-caliber in the neck. I think the two components (tension and seating depth) kind of pair up... if only half the neck is sized then as long as the base of the bullet is below the sized portion it doesn't really matter how much/little is in the neck because the grip isn't changing and release isn't impacted any more. Doesn't matter if it's the front half or the back half of the bearing surface being gripped, it's only so much there to hold. So I guess my answer could be extrapolated to mean keeping the base of the bullet below the sized portion of the neck maximizes useable case volume . That would be analogous to below the neck/shoulder on an FL sized case. I also set up throats to have ~0.040" of jump built in with the base of the bullet at the bottom of the neck, so I don't have a chamber to where I'd be less than 0.100" in the case neck with a reasonable bullet. Seems like a good set up a chamber would be to size half the neck, get a 0.020" jump, and have the bullet base below the sized portion of the neck and above the neck/shoulder junction. That's what I set my last reamer up for and I'll see how it goes. I could do something dumb like put a 110gn TAC-TX in a 300 RUM and have a massive jump with 0.100" in the case neck, but that's not a reasonable combination to start with. And also is impossible on many cases, the 300 WM being the prime example because the entire neck is shorter than one caliber length. [/QUOTE]
