Just found this site the other day and looks very informational. A bit about myself---- retired trooper, went to Iraq to instruct firearms as a private contractor for a year 06-07, then a year in Kosovo with the United Nations Special Operations 07-08 and return to the states in June to enjoy life. Been big into shooting all my life and now need to learn about shooting cast bullets in a Ruger GP100 357 Magnum. I want to use 125, 158 and 170 gn cast bullets, will probably start molding my own. Helped do some 20 years ago and sort of have the gist of it. Are tire weights to soft to use for deer/pigs? Are flatnose ok or need hollow points? Any certain style or brand of mold I need to get and do they need to be resized? Thanks for your help, I have a bunch of time off before I fly back and will look this site over for more info and help.
