The flash hole in the nickled case looks overly large to me...you did not enlarge it for some reason did you?
Whoops! read the part I missed where you drilled the flash hole. You are asking for trouble if you shoot those rounds. Where in the hand loading books did it tell you to do that?
Sometimes you get what you pay for, sometimes you only pay more for what you get.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
