Thanks Alpo,

My mistake at just learning to read my dial caliper... the lengths range from2.484 to 2.500.

Yes the brass I have is from different guns but nothing from the range, don't want to risk getting bad stuff. So what I planned to do was tumble the brass, run it into the die to full-length resize, decap it, inside neck expand, trim all brass to same length (if I need to crimp them) or at least trim them to the spec of 2.494 that the Nosler book says (if I don't need to crimp them), tumble again, prime, powder charge, bullet seat.

Maybe there is something I am totally not understanding. OK.... Full length resizing means returning the brass to the original new brass size, except for overall length. And neck-sizing just spreads neck big enough to accept and hold the bullet. Nooowww, doesn't the neck-expanding part of the die open every case to the exact same diameter? So why would do you say that if I plan to neck-size after the full-length sizing keep our brass seperate?

From what I have read so far about crimping... I don't need to crimp.? Maybe I should put a light crimp on the rounds we are going to actually pack around hunting. But if I do that,shouldn't lightly crimp them all to make it all all the more consistant?
