Here is the plastic shroud from the T3 after the .308 through a .270 trick. As you can see there might have been just a tiny amount of gas released. I had thought about getting the aluminum shroud before but after looking at the response to the gas and the way it was designed I was not concerned about it being plastic.
Hunt hard, kill clean, waste nothing and offer no apologies.
