[QUOTE="MagnumManiac, post: 2236814, member: 10755"] I aim for a bump that ends up being .001”-.0015”, which is AFTER any spring back. If you have sized .009”, then you have created an excessive headspace issue and your load, and brass, will be different to a properly sized case…so, yes, it can affect accuracy. It will also change ES/SD, no way around that. Do not be surprised if your cases show incipient head separations in one or two more sizings if you shoot them with .009” headspace. Cheers. [/QUOTE]
