Continuing precision testing my guns I took my old Savage 10FP to the range with boxes of six different commercially-available .223 Remington rounds. The rifle has a 24-inch 1:9 heavy barrel installed in a Choate Ultimate Varmint Stock, which makes it a superb bench gun. I mounted the 14x Nikon scope before I had found good Quick-Detach mounts, and before I had concluded 20x is my preferred minimum for precision shooting. But it’s still fine for setting a baseline with commercial ammo:
| Load | Avg Muzzle Velocity |
CEP (MOA) | 90% Confidence Interval |
|---|---|---|---|
| Black Hills 75gr Match | 2620fps | 0.23 | (0.19, 0.36) |
| Georgia Arms 69gr Match | 2705fps | 0.30 | (0.24, 0.46) |
| Wolf Gold 75gr Match | 2600fps | 0.59 | (0.49, 0.87) |
| American Eagle 55gr | 3170fps | 0.63 | (0.53, 0.93) |
| Silver Bear 62gr | 3000fps | 0.80 | (0.67, 1.17) |
| Wolf Classic 55gr | 3120fps | 0.84 | (0.71, 1.25) |
