A friend is selling me his TC Omega Z5. He let me shoot it and I used my Hornady sabots. It was a major job to push it down the barrel. I know some guys hate PB bullets, I don't want this to be a bash PB post, but my question is this. For whitetails and black bear here in PA would a 348 gr. AT PowerBelt with 2 pellets alleviate the loading issue and be enough for the game I mentioned? Any advice would be greatly appreciated, thanks!
