Correction: Whitworth Accuracy and Figure of Merit vs MOA
This video corrects a previous misinterpretation of 'figure of merit' accuracy measurements for the Whitworth rifle. The presenter clarifies that 'figure of merit,' also known as mean radial dispersion, is not the same as a group size. This metric, averaged over a 20-shot group, provides a more nuanced understanding of a rifle's accuracy than simple group diameter. The Whitworth rifle's accuracy is re-evaluated, with corrected figures indicating approximately 3 MOA at 500 yards, rather than the previously overstated sub-1 MOA. The video acknowledges contributions from John Simpson, David Minshall, and Rob (BritishMuzzleLoaders) for spotting and correcting the error.
