Ideally, I'd like to see quantitative data, but I know how forums and the interwebs work, so anecdotal commentary is welcome too.
As a reloader/shooter, do any of you have data to prove what variables make the biggest difference in your precision? I have the tools to measure all sorts of stuff, but it's very difficult to prove the effectiveness of minimizing particular variance, and the time involved would be prohibitive to anyone but an ammo company.
How would you rank the following measurements, in terms of how they affect precision in a quality rifle setup.
1) Runout/Concentricity
2) Powder weight (obviously not talking "two teaspoons", but within reason on a consumer grade scale)
3) Brass trim length
4) Bullet seating depth
5) Brass volume consistency (i.e. brass weight sorting)
6) Bullet sorting
Obviously, I understand that wind and shooter skill dominate the above variables, but I consider myself pretty steady. I can hold my reticle within a 1/4 MOA from my makeshift "wheat field prone bench", but my groups tend to be 3-5 times that with my new barrel, even on dead calm days.
I'm curious to hear what variables you all think are worth focusing on, so I can feel confident that I've addressed the "worst case scenario" as I go forward with practice. I'm happy with 1 MOA in my hunting rig, but if I could spend a little time in my shop to shave some off, I'd be willing to do it, but figuring out what to obsess over is tough without an unlimited budget...
