This will be my first pistol reload venture but I've been doing centerfire rifle for some time. I'll be loading for a S&W .357 mag R8 and a Ruger 77/357 rifle. I'm looking at the lead bullets for low recoil practice loads but am concerned about leading. I'm a big fan of the Nornady products and like their 140-158gr offerings in cowboy lead bullets. Any issues with leading by users? Thanks.
