Outstanding work ! If that is a 5-yard average of 2317 fps for 3 shots (2316.7) with 450-gr HYDRO with cap: BC = 0.250 MV = 2337 fps.
In a 24" barrel IIRC ? The LOAD: 450gn Woodleigh HYDRO Winchester case (trimmed) 75gn BENCHMARK (BM2) powder CCI 250 Mag primer 3.340" OAL (crimped)
Buy a donkey for the data.
Someday I hope to find some 400-gr/.458 HYDROs. Bobbed Bullets, Ltd. might have to make them by pulling the 500-grainers out of the Federal factory loads. That brass saws and files nicely !
