This is with the ultra 7 correct? Can I ask, are you able to shoot without ear pro comfortably?
I hope JLR answers, but when I shoot 6.5 through the Ultra 7 .30 can, I do not think it is hearing safe without earpro. .223 through the same can is borderline
ultimately, all these loads are supersonic so you will get the "crack" which hurts, the sound at the can seems to be fine
