Don't risk damaging your half-**** notch by setting the trigger first, and then cocking the hammer later. If you simply hold the gun against your stomach, and put your hand over the outside of the lock as you set the trigger or **** the hammer, the sound will be muffled to the point it won't be heard much beyond a couple of feet. Even you will have a hard time hearing it. ( You will actually FEEL the "sound" of the metal "clicking" as you **** either the hammer back to full ****, or set the trigger( I don't use a set trigger when hunting, unless I have a very long shot and a steady rest to use to help steady the sights on my gun).
When cocking the hammer back, you can eliminate the noise of "cocking" by simply holding the trigger back while you pull the hammer back, then release the trigger, and then lower the hammer to catch on the sear. [ The same "hold-the-trigger-back" technique is employed when cocking a Single Action revolver( BP or cartridge) when you don't want the sound of cocking the hammer to give away your position or action. ]
Practice these tips with an UNLOADED GUN, asking family or friends to stand a different distances to you and ask them if they can hear the sound of the action as you **** or set the triggers. You will soon learn that you can't rely on your own "ears", because sound travels to your ear drum faster moving through your bones, than it does through the air, to determine if a sound IS Actually LOUD at any distance from you.
Also, remember that in most of the country, Hunting season is held during the COLDER months of the years, so you probably will be wearing gloves, or mittens over your hands. If this is the case, wear the clothing you hunt in during your testing.
I found that cocking a glove with my other hand wearing a glove, muffling the sound by covering the lockplate, reduced the distance at which anyone could hear the sound dramatically. What is an mechanical "Ting", becomes a dull, soft "tick", which sounds much like twigs banging into branches when they fall. Animals take note, but are not alarmed. :thumbsup:
