I like the hardcast for deer as well. How many times have you got in close, only to see a hard quartering angle, facing away?
One thing to remember: "Remove Every Last Trace of Copper Jacket Fouling from the Bore". Lead bullets do not like Jacketed fouling. When you shoot lead past copper fouling you basically solder the lead on to that fouling, accuracy will suffer.
I think there are a couple of other companies that load Wide Flat Nose, Gas Checked, hardcast, if, your accuracy is still no good. If remember right they all were loaded pretty hot, ie: 1400fps, but I think that Garret had some loads intended for the Contender that were a little less stiff than the full throttle stuff.
I'm going hog hunting this spring, Handgun Only.
Have fun, watch your back.
