i have a question ,and i hope y'all can help me with it. i have a t/c encore and i have read on one of the forums i go to ,that i could cot part of a shotgun hull to fit the post of the forearm on the encore and this would float the barrel and make it group tighter.. i figure if t/c knew this they would put a washer like spacer there them selves ,but all i know about is the shooting part haha.would this make a diffrence or not. just wondering cause i was gonna use an o-ring instead
