Zee, I wish I could tell you the chronographed velocities of my handloads but being the lazy bastard I am I left the Chrony home..
However, the 454 loads were taken from the Freedom web site using a 7 1/2" pressure barrel (my 454 is 7 1/2") and listed as a factory equivalent load to their 300gr JFP showing a MV of 1625fps using 27.5 grains of AA#9....The reload info for the 275 Deep Curl came from Speer`s #14 manual showing 31.0grs of IMR-4227 had a MV of 1424fps from a 9 1/2" Redhawk (my Bisley is 5 1/2") while the 500WE was a hoge/poge of 50AE data in a trimmed case...
