Haven't loaded for my new 329PD as of yet. However, am using the Buffalo Bore "Reduced Recoil" load, which is a 255 grain Keith-type hard cast, gas checked @ approx. 1300 fps. Should be a good recipe for what could trouble you. And with the M500 grips installed, the recoil is no great concern .... about the level of shooting a M629 Mountain Gun ... at least to me.
