Sir Bob, Buy a donkey for the Crusade. Your load is noted, again. Add 15 fps for an extra inch of barrel and add another 9 fps for plugging your porting on the 24" barrel and your 2782 fps becomes my 2806 fps from a 25" non-ported barrel. Close enough to exact for a Crusader.
My BC numbers follow, from the RCBS BC Calculator with my local conditions, for what it is worth, BC calculated from Labradar 0 to 100 yards vs. manufacturer claim
510-gr W-W RNSN: BC = 0.316 vs. 0.284
500-gr Hornady DGS: BC = 0.267 vs. 0.295
500-gr Federal TBSS: BC = 0.260 vs. 0.328
480-gr Woodleigh HYDRO: BC = 0.198 vs. 0.192 [estimated by (480/400) X BC of uncapped 400-gr HYDRO = 0.160]
480-gr Hornady DGX-Bonded: BC = 0.245 vs. 0.285
480-gr Bubba's XTSX: BC = 0.235 vs. (Bubba was guessing about 0.200, so he is happy.)
450-gr Barnes TSX-FB: BC = 0.338 vs. 0.369
Like I said, this is worth what you paid for it.
