[QUOTE="Vaughng, post: 1914257, member: 114076"] The relationship between the trigger sear and the cocking piece sear has to be such that with the safety on you can pull the trigger and release it. the trigger returns to its position without interference from the cocking piece sear it does not fire when you let the safety off. What this translates to is that there has to be a bit more clearance between the cocking piece sear and the trigger sear. In this condition the trigger is free to move and return to its correct position multiple times without any interference, as the safety is holding the cocking piece rearward towards your eye. If you let the safety off it moves forward ever so slightly until it contacts the trigger sear it is now ready to fire. With the safety on , The trigger sear is in effect in its own space as that the safety holds the cocking piece sear back and the trigger sear is free to move and when released it will return to its position without contacting the cocking piece sear and when you let the safety off the cocking piece goes forward and contacts the trigger sear.[B] It will now fire[/B] This is a very delicate measurement as a few thousandths of an inch(.005 inch) will either work or make the rifle unsafe. If this relationship is not correct (in this condition) then it may fire when you let the safety off. The safety has to cam the cocking piece rearward when you activate it you should be able to feel this resistance I use a diamond wheel and hold the sear in the tool post of my lathe, this operation is critical and should not be attempted by hand . If you are not 100 percent confident take it to a gunsmith , Your original trigger may be able to be sorted the edge of the sear may be rounded giving alternating release pressures or may just need a bloody good clean.
