So This year will be my first year going out hunting since I was a teenager. I am looking at rifles now and I have noticed what I can only describe as a barrel wiggle? Not even sure if that would be the correct term. But there appears to be a gap between the barrel and the stock and when I grab both and squeeze I can close the gap. I have noticed this on numerous makes and models of rifles. Is this normal? It just seams it would be an issue to me. Is this something I should be concerned with when selecting the rifle? Any advice from seasoned pros would be great.
