Savage Barrel Zero Test
Testing whether a removed and reinstalled barrel can return to the same point of impact.
Why I'm Testing It
One of the things that makes the Savage bolt-action rifle interesting is its barrel-nut system. With the proper tools and headspace gauges, barrel replacement can occur seamlessly, allowing barrels to be removed and replaced without the traditional barrel-fitting work required on many rifles.
This capability raises a question I want to answer for myself: if I remove a properly headspaced barrel and reinstall it in the same Savage rifle, how closely will the rifle return to its previous point of impact? Specifically, I want to assess the barrel replacement accuracy.
Establishing the Baseline
This project starts with my Savage Predator chambered in .22-250. Before changing anything, I’ll establish a shooting baseline using the rifle exactly as it sits now.
The test will include:
- Four three-shot groups around the target.
- One five-shot group in the center.
- Seventeen rounds total.
- No scope adjustments during the test.
Remove It, Reinstall It, and Shoot It Again
After establishing the baseline, I’ll:
- Remove the .22-250 barrel.
- Record the barrel, barrel-nut, and receiver witness marks.
- Reinstall the original barrel.
- Verify headspace with the appropriate GO and NO-GO gauges.
- Repeat the exact same shooting test.
The original and repeat targets will then be compared and overlaid to see how closely the Savage rifle returned to its original point of impact, effectively testing the Savage barrel zero.
That is only the first part of the project.
Next Comes the Caliber Change.
The next step will be installing a 6.5 Creedmoor barrel on the same Savage rifle and documenting the complete caliber conversion. From there, I want to find out whether a properly set up multi-caliber Savage rifle can realistically serve as a repeatable multi-caliber platform. The goal isn’t simply to show how to change a barrel; the aim is to measure the actual outcomes when we conduct these tests.
