Winchester/Remington/Federal are just fine normally. Every manufacturer can have a bad lot.
Lapua brass is definitely a product that is sorted and QC (Quality Controlled) better.
My opinion is that no matter what brand of brass I obtain, I will put EVERY case through a concentricity/uniformity preperation procedure.
For example:
Every case is first Sized,trimmed,deburred,chamfered, primer pocket uniformed, and flashole deburring/uniforming. Then the cases are weight segregated into groups that are within 1%.
This kind of brass prep is what I do for long range shooting. (500-1760 yards).
With the Winchester,Federal,Remington,Hornady, I get more cases that are outside the bell curve for Consistnancy than compared to say Lapua or Nosler.
Lapua & Nosler have a way to better control thier end product.
If I have to throw away 4-5 cases per 100 of Rem,win,fed,Hornady, I am OK with that.
With Nosler,Lapua I may Wind up scrapping 1-2 or none.
The thing is, I can buy three cases of (Rem,Win,Fed or Hornady) to every two Lapua/Nosler. Or more.
Because I Shoot a fair bit, I usually side with economy. I have used mainly Winchester and Remington because of availability and Cost.
As far as one brass brand being stronger than another. Thats probably true to a point. I just dont load my rounds so hot that i have loose primer pockets after two reloads.
I Dont care If i have to adjust 21MOA at 1000 yards, or 24MOA. My scope
Dont care, but my brass will last longer "reguardless of Brand".
In the end, Lapua/Nosler are a more consistant product for the end user. But if accuracy is your personal addiction, you will have to work on them
Anyhow. Its your desision, and niether one is wrong/right.
