[QUOTE="vancewalker007, post: 2653179, member: 66917"] If memory serves, we would size down using several bushings that ended up with a lightly seated 7mm bullet using the 7mm STW bushing die being careful to not touch the shoulder and then we would shoot them fire forming them into the chamber shape. This would be easier now because you can buy a neck only sizing bushing die. We used 140gr cheaper 7mm bullets and shot light but not below minimum loads. Going from .308 down to .284 isn't hard. I would try some dummy rounds to make sure they chamber OK before jumping to powder and primers. You would want to step down maybe 0.008 at a time, that would be about 3 bushings. If you jump down too fast, you can cause a large amount of runout. Note - I didn't say this was cheaper. We had to do it to make cases period. [/QUOTE]
