I got my 5" 625 back from the smithy this week rechambered for the 460 Rowland. I had a 25 and 625 just gathering dust after years of shooting 45AR target loads. The 460 is a little more interesting. I loaded up a fresh batch of starter ammo with 185gr JHPs and AA#5 powder with loads ranging from 12gr up to the max load of 14.5gr. Accuracy was excellent with all loads but it was obvious that 14.5gr was probably a little on the hot side (although the primers looked good, extraction was difficult). I settled on 14.0gr as my max load for my gun. I didn't have a chrono so I'm not sure of the velocity (Clark advertises 1503fps for the 185gr JHP pushed by 14.5gr of AA#5 although no barrel length is mentioned). As expected, recoil was about the same as a similar 44mag load.
