    I recently posted a listing of various caliber on the TKO scale.

    I thought I would compare ranking on the TKO with ranking on the IPSC Power scale. The major difference is that the TKO scale takes into account bullet diameter and the IPSC scale does not. Also in the IPSC Scale as of 2008, a value of 165 or greater is considered major, while values below 165 are minor. IDPA uses the same scale but they do not differentiate between major and minor caliber.

    The comparisons are similar with the ranking slightly different, but close.

    P.S. The 25 ACP is even lower this time

    In the IPSC scale the 40 and 10mm and a few others moved up in power.
