Wow they must have changed something because my Hart brake didn't do that much on my Sendero in 300ultra. I actually had to mill further into the break just even with the furthest side of the the first set of holes to get it to work better. I did this to make it more like the KDF unit that works much better. At 85% a 300ultra would shoot like a 22lr.
