If you can only do one of the following to produce the best accuracy while reloading your match ammo, what one would you pick and why?
My vote is bullets by bearing surface. I have found that when checking bullets by bearing surface that bullet weight coincides with bearing surface. I find bearing surface to be the #1 cause for flier's.

My vote is for consistant Neck tension. Its the single most important part of accuracy in a string shooting scenerio. It can be accomplished by two ways. Either Neck turning which I find not too appealing or annealing the necks. That takes all of about 3 seconds per piece of brass.
Conistant powder charges, good ignition are number 2 and 3 on the list.
This is of course for Long Range Ammo and you can get away with alot more variables at 300 and 600 yards.
If you can feel variation in your bullet seating then you have issues that need to be attended too.

How much neck tension do you run? Do you find the more tension you run the more important annealing becomes? I run very little tension, 1 thou or less in my 6brx's.

Typically I run .001 neck tension on all my prone guns. So far never over .002 Even with that little neck tension I have found that after a few firings like 4th and 5th that I find that the brass work hardens at difrent rates dispite anal tracking on how many times a box of brass has been fired. I have loaded up 7 rounds left in the box and shot them to keep them all on the same cycle.
When this happens I can tell that the seating effort changes when seating bullets. This leads to two things..
1. In consistant seating depth
2. larger Extreme and SD than origional load work up.
Those may or may not show up at 600yds and in but they dern sure will at 1000yds. Or that has been my experience anyway.
Annealing has solved all those issues for me. I feel its single most important aspect of long range ammo.
I load my bullets right out of the box. Mostly Bergers for Long Range and they are just fine that way. They better be for the money we spend!!!
To finish your question ... Im not sure if more neck tension makes anealing even more important or not. Its so easy now I just do it to all of them at 3rd to 4th firing.
Turns out some of those fliers at 1000 yds WASNT me!!! Ha!
