[QUOTE="BrentM, post: 1977278, member: 61747"] Yes a machinist should be able to do that very easily. He'll likely chuck in a lathe and ream to whatever you wish. The polishing process is going to be very critical though. I'd have them mic it or take a piece of brass and measure the OD of the neck after sizing and figure out what you want. If you have a loaded piece of brass at .292 then you'll want .289-.290. I'd probably choose .289 for the slight spring back and expect .002-.0025 tension in the end. With proper annealing it should work fine. My guess is that right now your brass is being undersized .004. I know I used 6.5 measurements and you have a 35 cal. I just don't know what those are. Same principle applies. [/QUOTE]
