[QUOTE="Greasegun, post: 1775757, member: 112196"] Curious what you long range guys consider acceptable shoulder bump variation. I was able to get my spread down to .001" by switching to a different sizing lube. My sized shoulders now range from .001"-.002" shorter than fired dimension. I do notice a bit of sooting beyond the neck, partially up the shoulder on some cases after firing, but most seal off good. I do not anneal my brass, although I wish I could. I use this wilson gage with a .0005" test indicator to measure (see pic) [/QUOTE]
