been around savage rifles awhile now, i have a cabelas 10T in a bell & Carlson 2997 stock, i noticed my trigger got real light and when i closed the bolt fast it would be like a slam fire, i took it apart and saw the pin that goes thru the sear backed out to almost out of the hole on the sear, i did correct it by instaling a tight plastic washer over the end of the pin, only reason i see how this can work it's way out is probably because the inside of the stock has too mych clearance in the area where the sear pins. is this possible or any other reason this pin can work its way over
