.2505> .248 > .2465 .246 > .2455 .245 > .2450
I have some once fired Winchester .223 cases I want to size to .244. I measured them and the necks measured .2505 in diameter. I decided to take them down in stages to minimize stress on the necks, so I used a Redding titanium nitride bushing, ran 5 through, and measured them at .2465! I replaced the .248 with a .246 bushing, sized them again, .2455??? Used a .245 bushing, sized them again, finally .2455.
Has anyone ever experienced this? I am fairly new to rifle reloading and haven't read about this situation. How can a .248 bushing yield a .2465" neck?
I have 300 of these sized to .2465 at this point, but I don't want to make a career of neck sizing ("Yeah, old callgood, he shoots just so he can use his neck sizing die.)
But I'd still like to ease the brass down to .244. so I may omit the .246 and go directly to .244 from .246.
