IMHO.....if you're loading .38 special with H110/W296, you deserve to blow your gun. I believe what Skip is implying is that because a proper charge of H110/W296 almost fills the case in .357, double charging is impossible.....and since a nearly full case is a safe load in any modern firearm, that it's impossible to put enough powder in a case and still seat the bullet to cause a kaboom. It does not mean you won't shoot the gun loose, it just means it won't blow up in your hand.
