I shot a 14 year old P.S.E. thunderbolt got it at a pawn shop gave 100$. I know it kills hogs and after going bow only last three season found out it will kill deer. In my opinion no need to change if you like it. Bought it 13 years ago.
Of course my deer rifle is a 1945 British 303 so you can tell if I like something I stick with it. Why by new when it still kills.
