My most recent mistake was the other day . Loading 38spl for the first time , no that's not the mistake haha . I have a little Ruger LCP or R I for get ( the revolver ) and started looking up the load from minimum to max , actually +P . Anyways , counted out how many cases/primers . Seated all the primers then started loading the rest of the components . I got to my 4th increment of charges when I realized I was loading 6 rounds each for my 5 shot revolver . Got to love the mistakes that won't kill you and make you have to laugh at your self .
