How much do you personally trim off your cases?

[QUOTE="Mikecr, post: 1090804, member: 1521"] I measure cartridge base to chamber end with Sinclair's gage. Then I set the trimmer for -1thou. With fire forming the necks will pull back more a small bit from this(~5thou), and given that I don't FL size, I haven't needed to repeat trimming. Seems the trimmed stay within a few thou of each other. The reason I like close is to mitigate carbon buildup at chamber end and reduce blow by(neck sooting). Both affect ES with mid-size hunting cartridges. For cases I can't trim this close, I don't really worry about trimming at all. I want these cases long as possible. Between normal trim length variance -vs- gas blow by, I'll take the length variance. [/QUOTE]
