I have had worse hearing problems from the high velocity smaller caliber rounds like the .223 than using the .338 Winchester magnum my preferred caliber in Alaska.
I have made my own suppressor but I would not just yet start using it while hunting, mostly because our critters tend to be bigger, badder, faster and more dangerous. the can works great on my .22 pistol and subsonics or even single fire short rounds. Good for backyard plinking.
