When you're reading bbti graphs account for this
in every case with the T/C Encore the length of the barrel was measured from the end of the barrel back to the breech face. This is how semi-auto pistols are measured, but revolvers are measured as the length of the barrel in front of the cylinder gap. Take this into consideration when comparing calibers using our numbers.
The Ballistics by the Inch website shows data two ways. From the same barrel as it is cut down, and from actual revolvers with different barrel lengths.
