So here I am, trimming .308 brass on my Hornady Case Prep Center, for my precision rifle.

I'm having some trouble with consistency from case to case, with the measurements ranging from 2.004 - 2.006. My question, is whether this variance is acceptable, or something to actually concern myself with.

Will my #### fall off, here? Or am I being too concerned about something which will have a negligible effect on my reloading and shooting?
 
I there was .002" case neck THICKNESS difference, you might rightly be concerned. But .002" case LENGTH variation is going to make zero difference. Regards, Eagleye.
 
Not that a .002" diff matters much if at all, but you could try putting the same amount of force into the cutter's crank handle for each case.
This might reduce the 'trim-to' variation to 1 thou
 
Unless you are shooting match 1000yard comp then don't worry, almost all the time not going to matter, but the old adage is if .002 is ok then is .005 ok or .010 ok, come up with a max and go with it all the time.
 
Everyone is actually being really nice to you. Your dink is going to fall off.:eek::runaway:
 
So my #### is going to fall off? Well... I guess that means that I'm a Liberal, now.

Seriously, though, thanks for all of the replies. This reloading thing is new to me, so it's all a gradual learning curve. I'll try to keep my pressure on the handle more consistent, and see if that improves things.

I love the prep center, but to be fair - I have nothing to compare it to. I don't find that the tools turn too slow. Any faster, and I think it might be too fast. Maybe some people are capable of using the tools while they're turning at high speed - but I don't see the need. That's just my take on it, though. I haven't ever found myself going "Damnit, this brass is taking forever."
 
My Lee hand trimmer produces cases with less than 0.0005" variation in length. So if you are concerned you could buy a Lee to touch them up. Would only cost $5 or so. The down side of the Lee is that there is no real choice in length. The gauge is set and you cut to the cartridge "trim to" length.

That said, I would not worry about a 0.002" variation or the impending loss of vital body parts.
