It really doesn't matter if you believe that is a gun or not in BL's bedroom. <modsnip - no link> It is not much of a stretch of the imagination to think he would take his gun on the camping trip with Gabby. And now we know BL committed suicide with a gun. If you google bullet holes in trees, you will see that they look a very specific way that is very different from nail holes. If you compare the bullet holes in the crime scene photos to the photos online of verified bullet holes in trees you will see that they match. The bullet holes are at different levels. Some are low enough they might have been from target practice. Others are at the level of Gabby's torso or head. Hard to know exactly what happened without the FBI's report. But modern day campers normally don't put nail holes into living trees to hang stuff. That's a major no-no. At Grand Teton you use a bear box for trash bags, you cannot hang trash from trees there as it would attract bears and other wildlife to your campsite which would be dangerous and if you got caught nailing a trash bag to a tree, the fine would be upwards of $5,000. Also, if you look at photos of BL's hammock, it is tied to the trees with a bowline knot, never nailed. This technique protects the trees from damage and keeps the hammock secured.
