Ramset power testing..

We are using a ramset style tool to shoot in nails into concrete. First time I am ever using something like this and its quite fun. Its basically a 0.27 calibre gun which shoots nails. Its safe to use because you need to push into object before it fires. The physics behind it are quite interesting on how it works. Feel free to read more here:

These are my first test shots in some scrap concrete. On the left is power level 5 and on the right is level 4. You can see that level 5 was too much for this type of nail and we are using level 4. I tested with level 3 but it wasn't enough to properly embed the nail.
