[QUOTE="hubel458, post: 1273936, member: 6474"] I use 11 steps make a case, face off rough end., Cases fired many times, and we section couple, no stretching away from base, Neck lengthens, which no problem as chamber has room. More neck to hold cases out for better fit of bullet in freebore. Cases without bullets way down in powder space have less pressure problems and stretching. Shallower shoulder , bullets loaded out right, less case sticking at top pressures. Expanding cases with both belt and shoulder contact shows no stretching with fireforming loads( fast powder, filler, plug) or hydraulic forming. And we still have over .010" taper per side, along with shallower shoulder, bullets loaded right, it works. If we load bullets down in below the bottom of the shoulder, that a lot do, , we need twice as much taper, and still will have sticking long before we get to our speed we have now, where maybe only .020' of some bullets are below neck, and others nothing below. That is why I set up old barrel and freebore just to check where bullets set, I won't do it, setting bullets way down in, and won't tell others to do it...Ed [/QUOTE]
