i have a bit of this brass that i believe was fired in an M-60. quite a few of these have small dents in the sholder area, can these be reloaded and used in a .308 marked rifle.
I have uses Imperial Case lube and Hornaday Unique lube. The Hornaday lube has never let me down and is easier to find than Imperial. You can size many thousands of cases with the container and nary a one will stick in the die. It also makes sizing pistol cases in carbide dies, like the high pressure 44 mag go much easier. I lube VERY LIGHTLY every few cases and the effort to size them drops by half.
