there are many variations of the magic solution however the basics ar 2% benzyl alcohol and 10-20% benzyl benzoate. some increase the BA to 3 or 4% but the higher the ba goes the more painful the shot.
There are two different conversations going on. If we knew what the "magic" solution actually was and not what we "think" it is then there would be absolutely no need for the word "magic" now would there guys?
My guess guess BA and BB, the more reputable the maker the more exotic you may get, something to really break those pellets down quickly!!
