It depends on the gun and the parts. I do love Gunziila for all my guns except my trap guns because if you shoot a lot of rounds it is cheaper to use Hoppe's than Gunzilla. Gunzilla is not super expensive and with pistols and rifles you don't have the carbon buildup that shot guns do, but for pistols and rifles it takes less to clean it and it lubricates.
It is also all natural, non-toxic and does not attract dirt like other lubricants do. http://www.gunzilla.us/products.html.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
