| Measurement | Before | After |
|---|---|---|
| Ammunition | Hornady factory ammunition; bullet model unknown | Custom ammunition with 215 gr Berger Hybrid Target |
| Group diameter (CTC inches) | 2.04 in | 0.80 in |
| Average velocity (fps) | 2,935.6 fps | 2,817 fps |
| Standard deviation / SD (fps) | 16.1 fps | 7.0 fps |
| Extreme spread / ES (fps) | 49.9 fps | 17.4 fps |
Each group contains 5 shots at 100 yards. Velocity statistics describe the same 5 shots in each configuration, recorded with a Garmin chronograph. CTC means center to center; fps means feet per second.
What these results mean
Results reflect the combined equipment and ammunition changes; individual effects were not isolated. One five-shot group per configuration is shown. Results are specific to this rifle and test.

This Christensen Arms rifle was evaluated and configured as an existing-rifle project. The documented outcome reflects the combined setup and ammunition changes, not a comparison that isolates any single modification.
BHA evaluation, setup & development
- Installed Area 419 Match scope rings; bedded the scope rings and Picatinny rail.
- Adjusted the trigger as part of the accepted rifle setup work.
- Replaced the previous suppressor with a Replicator Ventus 30. Accuracy development used the new suppressor.
- Removed the sling-swivel-mounted bipod, installed an Area 419 Arca rail, and configured the rifle with an Accu-Tac bipod.
- Evaluated five bullet designs and seating-depth variations for this rifle; the final documented configuration used the 215 gr Berger Hybrid Target. Loading recipes remain private.
Test context
Both groups were bench-fired at 100 yards. Each target shows five shots, with chronograph readings from those same five shots obtained using a Garmin chronograph. Exact front/rear support details were not specified. No mechanical-rest use or measured 1,000-yard group is claimed for this case.
Illustrative constant-angle scaling only
1,000-yard baseline group projection
Constant-angle projection of the measured 100-yard group diameter. These are not measured 1,000-yard groups or total-dispersion predictions. Additional velocity-driven vertical spread, wind, and other downrange effects are excluded.
Measured 100-yard group diameters scaled by 10. This graphic is not a bullet-drop chart or a firing solution.
Source note
The original baseline target’s rifle field was labeled ‘300 Rem Mag.’ The owner confirmed the rifle is a Christensen Arms Model 14 chambered in .300 Win. Mag.; the source photograph has not been relabeled. Public target details omit lower ammunition-dimension fields but preserve all impacts and handwritten group/shot-count annotations. The supplied report predates the added Arca-rail and bipod context; the updated work summary on this page includes those owner-confirmed changes.
