Well my bow is a Browning micro adrenaline and I shoot with a release. My bow used to shoot great when it was set at a 40 pound draw weight, but now since I increased it to 50 pounds it has made everything go crazy. I guess I will try the 100gr. broadheads and maybe a heavier arrow. I am pretty sure my drawlength is like 28 inches, so I dont know if that helps.
