Thank you so much for taking the time, what I was looking for! Also found this old thread here.

Clicked the linked "Velocity Estimator", left everything default but MV = 2580 (Hornady #81528 24" listed MV) and New Barrel Length = 12", came up with 2281 FPS. Which calcs what appears to be another in the ballpark data point. Thanks again VC!
