Yeah, I think Sierra makes a pretty good bullet.Referring back to my 6.5 creed and 600 yard trouble. Got the 140 Sierra bullets. Didn’t do any load development. I just put the same charge in as used with the hornady bullet. The groups at 600 went from 6-8 inches to between 3-4 inch. With load development and seating depth I’m sure it will get even better. Bullets matter. Edk
