I broke out the chronograph today and checked some velocities today. I brought the muzzleloader too since the .450 bushy and the .50 cal muzzleloader are shooting the same Hornady 250 grain FTX bullet (.452 diameter same B.C. & S.D.)
.450 20" barrel clocked in at 2238 FPS
CVA Optima V2 .50 cal 26" barrel got me 1635 FPS with 100 grains Triple 7 pellets.
I need to try 150 grains next time I break out the chrony.
*the 250 grain Hornady SST 20 gauge slug advertises at 1800 fps*
Totally pleased with the results.
