True, the name has changed, but the load has also. For years I've shot WinXX in 12ga 2.75" #6 (red hull) with 1-5/8oz shot @ 1250fps; the model number was X12HXCT6. These are no longer available. The new 12ga 2.75" #6 WinXX is 1-1/2oz shot @ 1300fps, with a model number of STH126; that is the same specs and model number of the High Velocity that I patterned early last year. So to me, the High Velocity is now called WinXX, with the old WinXX no longer in production.
In my gun, the HV shells never patterned that well. Both the red hull WinXX (X12HXCT6) and WinX did better.
