How much is barrel life affected by going from 2900 FPS to 3000 FPS with a 230gr bullet? I have a 30" barrel so 3000 is definitely possible. I'm currently at 2900 FPS with 76gr of H-1000 with ADG brass and it seems like a fairly moderate load. I'm thinking I'm saving a little barrel life by sticking with 2900, but would like some confirmation.
