For the life of me, I can't find any good load data for the Sierra 165 gr JHP. All that's out there is reduced recoil, slow load data. If we're getting 1850-1900 fps out of a 180, we should be able to get over 2k with the 165. I know, I know...why pump up such a little bullet for a big gun? Because hyper-explosive bullets against water jugs = tons of fun! Right now, were experimenting with 20 gr of Unique with a tight crimp for pressures. Will chrony soon. Have to use a faster burning powder because of the limited capacity in the 44 mag case.
