I have two Red hawks one 44 mag and one 454. I was shooting the 454 at the range a couple weeks ago and had several miss fires. I thought it might be because I was using CCI SRM primers. I usually just use CCI small rifle primers. After several minuets I looked at the primers on the miss fires and it seemed the dent was shallow. I took the gun home took it apart and cleaned and inspected then put back together. I went back out to the range today with new loads and I used Rem 7.5 primers instead of CCI mag primers. Had the same problem with miss fires. About one in every 4-5 shots do not go off!!! I have shot hundreds of rounds through this pistol with no problems before now. When I look at the transfer bar it does not cover the entire firing pin as my 44 Red hawk does. I would say about a 1/4 to 1/3 of the firing pin is above the transfer bar at full cock. Not sure if this is a problem. Has anyone had this problem?
