Unity - Destruction physics asset for Christmas

So I got some money for Christmas and I decided I would actually spend some of it on quite dramatically adding some mechanics to my game, I bought an asset from the Unity asset store and these can often be very well put together extensions for unity that let you put in all kind of game mechanics very easily depending on what you want. I tend to only buy them for more complex stuff and I decided I would get a destruction extension and thankfully it works absolutely great, I'm still figuring out how it all works but I'm having a lot of fun with it, this will make things a lot more interesting and less static for my game as I can put in stuff like destructible cover and so on, I wonder how this is going to react if my alien starts shooting at the player.

Edit: I checked out the problem with the physics when the bullets were hitting, it looks like it's a problem to do with the size of my spheres, so after looking things up what I will most likely to do is use some form of raycast system to fix this and have it shoot based off the raycast rather than constant physics calculations, then it should be more accurate.
