[QUOTE="BountyHunter, post: 469564, member: 12"] JE Well I certainly do not have 50 years of reloading, (only 45) but 25 years ago I learned something, that you must have missed, so here is a news flash. FYI belted cases are used all the time in LR BR (7mm Mag, 300 Win Mag, 300 & 340 Wthby and derivatives for example) and they are set up to FL size and headspace off the shoulder not the belt as some think you must do. Obviously you did not know that based on what you said, so I can see your confusion and why you think it is personal. Well only one belted case is designed to headspace off the belt and that is the original H&H case, all other belted cases leave .020-.030 of gap from the case to the chamber shoulder for the initial firing and if you resize based on headspacing off the belt, the case will often separate in about 3-4 firings. Custom honed FL bushing die costs $80 from JLC precision if it is a caliber that has a redding body die ($27). So I fail to to see the valid arguement that someone can have a $1500-4000 rifle, $500-2000 scope and somehow we feel the need to say you must NS only because that is the best way to get a chamber fit, when better dies are out there (even for factory chambers) that will not work the brass as much, fit tighter and basically proven by the guys that live for extreme accuracy to be the better method. A case that has only .001 or so of pushback and will chamber every time; and will be as tight in that chamber as possible . Admittedly a min variance reamer and matching die is the absolute best of both worlds, but not necessary. With belted magnum cases that are FL sized with a fitted die going 20-30 firings on a routine basis, works better than NS only and throw away when the bolt locks or does not chamber. I have over 30 firings on a 300 wthby and 300 Baer FL sizing and you never see anyone saying that NS only will do that. Boomtubes Lee Collet and a body die still equals FL sizing also, just two steps. That point is often not stated by someone touting NS, but when you dig down you find that they have discovered that they have to do it. Sinclair Intl tech reps just posted a great article on setting up FL dies and NS only today on 6mmBR.
