I never have and can't see any reason why you should.

No, Trim them up and load em. Shoot them, and then fully prep the fireformed cases for ROUND 2.......Ready.....Fight!

Here's a thought on trimming NEW brass....Some trim NEW brass before firing and some don't. As long as they're not longer than 1.845 and the mouth is parallel to the base your good to go without trimming.Now if you know your chambers length by measuring it, custom fit the brass to your rifles measurements. Otherwise stick to the book spec for case length.Some here on the forum have complained about brass shrinking when fireforming. Yesterday I fireformed 20 pieces of WW.243 brass. Some grew by .005 and some shrank by .005. Sure glad I didn't trim the ones that came up short! That's just my 2 cents and it's worth every penny if you have a 2 cent coupon
