While Hawkmoon's description of my reloading methods makes me sound like a bench rest shooter, I'm not really that anal. In reality. . .
My brass gets sorted by headstamp only because an undersized resizing die is used on thin-walled brass. This done to maximize the grip of those cases on the bullet and minimize the amount of bullet setback suffered when those rounds are chambered. Got a lot of thin-walled brass. Some folks can be real persnickity about their COAL's just after reloading, but the only COAL that really makes much difference is the one when the round is chambered and the hammer is falling.
And if you think COAL (and seating depth for the same bullet) stay the same between the time a round comes off your press and the time it's fired, re-measure the COAL of a top round in a full magazine after it's slingshotted into the chamber (but not fired). You may be surprised.
Only bullets weighed are those I cast because I'm a really bad caster. The SAAMI spec for 45 Auto bullet weight is ±1.5% and even my nice looking ones can exceed that by a fair amount.
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind. [Lord Kelvin]
