there is a trick to loading lead. and if you go to fast or to slow with your bullets, you will get leading in the Barrel. and it can damage a good gun fast, saying that becarefull where you get your Bullets. I have picked up Lead bullets at Gun shows , tested them on a Seaco hardness tester. and they have Been all over the place. Most cast load books are for Lyman #2. a little harder than clip on wheel weights. but a lot of guys are throwing the stick on weights in and they are just over pure lead. a good test if you have a good scale . say if you are shooting a 158Gr. bullets the The more the bullet weighs 159Gr, 160Gr, the higher the lead content. inturn the softer the bullet. pushing to hard a bullet to slow will lead as will pushing to soft a bullet to fast. I cast my own bullets and heat treat them, but I still never go over 900 FPS unless Gas checked
