Very high velocity. Accuracy poor to non existent.
Tried them in .308 Win. / .30-06 and .300 RUM.
Sometimes the Sabot travel along with the projectile.
The Sabots petals can ruin Chronograph Detectors.
.300 RUM achieved over 5,700 fps for one shot ,the next wrecked the detector.
You can't get the same powders that Remington loaded their Accelerators with.
Remingtons' .30-06 Accelerators didn't fair any better then handloads.
Interesting waste of time.
E.Brown carried / carrys Sabots .224 to .308.
