I'm having a little issue with my cabelas Hawkins percussion cap rifle and hope someone out ther can help me out. When I cock the hammer, pull the set trigger, and then pull the 'bang'/front trigger, the hammer comes down to only the 'safety' position (please forgive my lack of the proper terminigoly as well) and does not strike the cap. When I cock the hammer and simply pull the front trigger, skipping the set trigger, it works fine. Any ideas on how to fix this? I would assume a semi-handy guy could fix this without bringing it to a gunsmith? Thanks in advance for your help!
