This is another subject that has a lot of different opinions.
I learned what little gunsmithing skills I have from a master builder
and bench rest shooter that was so particular that even the color
of the brass made a difference.( he said it was because of the neck
tension that different brass imparted on the bullet even though you
did all the right things, trim,ream,turn,brush etc).
And he said that nothing was a wast of time if you wanted the best out
of a rifle.
I weight sort all of my brass when I get it and store it in batches that are
clearly marked for future use. In my loading data I record the brand,
number of firings, trim length,neck thickness of the brass so that later
I can match the new brass to the old brass. This allowes me to duplicate
my favorite load and not have to start all over with testing .
So that is why I weight sort all of my brass along with all of the other
And as boss hoss said it may not be nessary but "All" of my hunting rifles
will shoot under 1/2 MOA and most under 1/4 MOA with the best 4 shooting
.031,.054,.077 and .092 groups. (all of these rifles are hunting rifles and
weigh 8 to 12lbs).
In the pursuit of perfection I leave no stone unturned.
Why build a custom rifle
and feed it junk like the factory ammo.
Remember this is just My opinion and others are entitled to theirs so
you must make the final choice.
