I'm casting my own bullets from WW. Mostly for .357 and .44 mag. My reloading manual says that under 1400 fps that checks aren't really needed. It also states that liquid alox will take care of most leading problems and in fact states that there's NO leading problem if it's used. I'd like to hear from you veterans on the subject. At $35 / 1000 it seems pricey to have to use checks. I'm thinking of using Titegroup and Greendot with 158gr for .357 and Greendot for 310gr 44 mag. Both loads are well under 1400 fps.Thanks
