Did you not get my reply yesterday chap when you asked the same question? Wrapping something around the head isn't the solution. You need to make sure the lengthmaster is positioned correctly. I have a few videos in the lengthmaster section explaining this in detail.
You should be strapping in below the head. I would look through the LengthMaster stickies and the Wrapping forum to learn a style of wrapping that will work for you. The head should ever be crushed in the LM, it should be clear of the chamber.
