Jordan, they will be fine. That's all I shoot, you still have to hit them if the BB's are round or not.
They are 2 3/4", the FPS on them is 1450 for 1 1/8 oz and 1550 for 1 1/16 oz, that is hauling ***, never saw steel hit a duck so hard until I shot these. I used to shoot all the big shells, now all I shoot are these in my Beretta, and life is good, best shooting I have ever done, don't have to lead much with these, just point and shoot.
