Switching from Lapua to Pererson brass for my Dasher, what are the issues?

I couldn't hit my accuracy node with Peterson so I went to alpha and couldn't be happier.

What bullet/powder combo are you using?

Have you annealed your many time shot brass? If the primer pockets are still tight, then get it annealed and keep on trucking! I mean shooting it!

I’ve shot Lapua fire formed Dasher brass for three barrels, then I decided to give Peterson a try.

My first issue was that I was shooting a Lapua Blue Box No Turn neck at .2704”. The Peterson has a thicker neck which would only give me .0014 total clearance, a bit too tight. I turned the Peterson’s neck to about .0122”. That gave me .003” total clearance. I shot a moderate load the first loading. They shot well and resizing them I had to go to a .266 bushing to get the neck tension I wanted.
All in all they are quality brass, but a .272 neck chamber would have been a better fit.

A miracle……….

Took months of searching for a box. Contacted Lapua and they said they keep making them and just keep searching.

If that wasn’t enough of a miracle I also found 1000 LR primers (federal) the same day.
