[QUOTE="Doug Brownlee, post: 746021, member: 37106"] I am trying to take the variation out of the case neck to achieve equal bullet tension on my 270 loads. I read on line the new Winchester brass was .015 thick all my brass mikes out to .012. The author also stated he trims down to .0135 mine clean up at .011+or- .0005. I guess it boils down to how much clearance is acceptable between your chamber neck area and your loaded cartridge, and how can you figure out what your chamber was machined to. [/QUOTE]
