i was wanting to go bow hunting this season and didnt get around to getting everything readyso i was thinking of getting a new bow because the one i have may not be strong enough...(it has like 45 pounds i think) and i was wondering if 45 would be enough or i would have to crank it up a bit.

Thanks,

45 is plenty for whitetail. Your trajectory won't be as flat as a 65-70 lb. bow, obviously, but you should get pass-throughs at reasonable ranges. A lower-poundage bow with an arrow on the heavy side is a pretty low-maintenance and foolproof setup.

45 is OK . be confident with the broad side shot and keep it under 20-25 yards
if you can handle more and it is able to be turned up more poundage than i would try that.
also practice, practice,practice

I shot my first 2 bucks with a 45 lb. recurve with Bear Razorheads. I spined the first one after passing through the shoulder blade. The second was a pass-through, taking out both lungs. Both shots were close though. Ten yards or less.

I would check with Your local State recomendations on the lowest amount of poundage Your allowed to Hunt with just to be on the safe side?

45# with a good cut on contact broadhead will be plenty, if legal in your state. I have a good friend that shoots 45#'s and she kills elk on a regular basis including a 365" monstor last year. At 23 yards broadside, she got a clean pass through on the monstor.
