Browning a5 barrels are fairly easy to bend. I use to place a bag of shot on a flat surface and hit the barrel like it was a bat and the bag was a ball. I've seen trap shooters place a barrel in between the crotch of a tree or between boards on a fence and bend it that way. It was all trial and error to adjust for poi. My browning was bent while loaned to a friend. Don't know if he dropped it or used it when he fell walking across the marsh. But it was clearly bent which was not that hard to fix.
