I got a 7-08 with the ventilated Boss right after they came out, which I sighted in while wearing hearing protection. No problem. Then I used it in Wyoming for Mule Deer. I took a shot at about 165 yds and no hearing protection. It was really loud, and my ears rang for about a day.
I contacted Browning and told them that they should warn their customers about the very loud noise blast. They told me that I could buy a non-ventilated device that would not cause hearing damage. I told them I did not plan to pay for something that they should have warned their customers about ahead of time. They sent the non-ventilated device without charge. It works pretty well. But the ventilated device is pure trouble.
And hell, I did not hear that well to begin with.
I had to laugh a little bit at the above in shared misery. I acquired a browning bar in .270 with the boss system, and ported. Shot it at the range with muffs on and highly impressed took it deer hunting. Saw a deer, fired, and thought i had lost my hearing. The port came off, the non ported option went on, and perfectly happy with the rifle except for two things.
It is heavy.
and I don't like carrying a loaded round in the chamber, and you do have to let that bolt slam shut in my opinion for positive lockup. But it is quite accurate.
