Re: New to the crossbow world.....got some questions.
Welcome to the crossbow world. Questions are always welcome. This is a good time to get aquainted with your bow and get the right combination of arrows and broadheads that work great with your set-up.
Arrowhead will have specific recommendations for your exact bow and he will chime in. I don't have alot of range time with Barnetts.
As for generalities. I would recommend upgrading to some quality arrows instead of the factory stuff that comes with many bows. Gold Tips, Carbon Express and Victory all make excellent arrows for crossbows. Broadheads are a personal choice as most these days are quality. Comes down to what flies good in your set-up. A good starting point would be Wasp Boss's, Jackhammers, G5 Strikers, Slick Tricks, Muzzy MX-3,4's. Most crossbows seem to like these.
The key will be practicing and knowing the exact trajectory of your bow. As with all archery equipment, the range is limited and shot selection crucial.
Arrowhead will set you right.
I support all hunters, regardless of weapon or technique!
