I am a newbie when it comes to reloading and I messed up on the amount of powder. I had to pull 50 rounds and start over. When I pulled the bullets I notice they were dented like a mushroom. 1st question... am I crimping them too much? 2nd question... can I re-use these bullets? ( side info... I am going to be using 10.4 gr of Accurate #7 and the bullets are 180 grs. with a Remington primer) Wanna kill these ads? We can help!
