Hi I have axis(labeled edge)in .308Win that I have had for a while. I put a Boyd’s stock on the gun as well as a Timmney trigger. The gun had been great to me able to touch steel out to 500yards no problem, one day I was shooting with some buddies of mine and I loaded the gun went to turn the bolt down into battery and bam it fired. I had never had any problems with it until this time. I then tried to load another round thinking maybe it it was just a bad primer or something weird and it fired again same thing two times in a row. I don’t know what could be doing this the trigger is adjusted to 3-3.5 pounds and didn’t think that was too light for a gun to do such a thing, but any thoughts would be appreciated. Thanks
