RE: are these broadheads ok for a 50lb pull bow
I have to agree with some of the others...Not enough pull wieght behind it to shoot a mechanical, or even a hybrid mechanical (cut on contact front with mechanical behind it). I would get some type of cut on contact - either 85 or 100 grain. 2 or 3 blade would do, and should get you plenty of penetration on the shot even at 50#.
