Loadbreak welcome to the forum. It is good to have you here.
Yes, a lot of people use the T/C pink tape or the use simple white Teflon Plumbers tape. This is to help the breech plug release after being shot. You can also use an anti seize grease on it and it will do the same thing. I personally use a combination of the two. I like to know that plug is going to come out at the end of the day.
The reason a lot of them use the tape is there is less mess...
