RE: What Grain Powerbelt
A5: Did a doubletake with your name there. LOL
If you are hunting whitetails, then you are good to go. Don't see any reason why you would ever need to change.
However, I hunt elk and a 223 gr would not do the job in all situations. I do have some 270 grain platinum Powerbelts that I want to try on whitetails though.
