The writer’s results largely mirror those from my own testing.
After doing a lot of statistical work I figured out that while you could get really great results from reformed Win or Lake City brass, it’s probably cheaper to just buy Lapua and be done with it. You wind up throwing out too many pieces that aren’t within some specified weight range. It’s definitely faster since I have other things to do than trim neck walls to get consistent thickness.

Next time just neck size to .264 some Lapua .308 brass and compare with Lapua .260 brass…

Ive use a lot of lapua and switched to Winchester becuse I found it to just as consistent as long as the brass was all the same lot. But that applies to the lapua as well. The Win is also 15 grains lighter.

Editor: I shot Winchester in a .260 and disagree with your comment. Neck tension on WW all over the map. I had to neck-turn and then anneal to get consistent neck tension, and it still did not shoot as well as Lapua, and did not hold up to repeated firings near as well.

I’m not disagreeing that Lapua brass is more uniform in weight than Winchester. However the 20 case sample size is very small to draw conclusions. I weight sort my brass so I have the exact data on hundreds of rounds, and in 223 Match the Lapua will not hold that same range for a much lighter case. More like 2+ grains.

And while I also find Laupa necks to be more consistent in thickness than Winchester, you have to use the correct tool to measure case necks. And as mentioned in the summary, calipers are not the tool. Use a ball micrometer that reads to 0.0001″ if you are going to do a comparison.
