I got a bunch of size 5 eagle claw barrel swivels and I want to know if anybody has broken these. I ran out of the ones I had (I forget the brand name) but they were proven to 300lbs or something like that. I know these eagle claws are not as tough but do you think I will have any problems with big flatheads on them? I doubt I will run into any over 40lbs but Im trying for bigger than that. what do you think?
