Default Re: Taylor Knock Out (TKO) Scale

Quote:
My calculations of the 10MM Auto are a bit different.

180gr bullet X .400 dia. X 1287fps / 7000 = 13.24 TKO

1287fps is per Hodgdon data, I run 9.2gr of Longshot to 1305 avg fps.
The 165 grain bullet in my calculations is the reason for the lower TKO value
