I used to be real persnickety about it...

Trimmed every batch when new and kept them together. I asked the same question and everyone pretty much said I was too OC about it so I stopped. I don't know if I see any accuracy difference but I definitely feel the difference when crimping. I've been slowly getting all my batches trimmed again simply because I like uniformity. I don't worry about my ACP cases since I taper crimp them and I've yet to have one grow to where it wouldn't fully chamber.
