Chronograph is sometimes a better way to identify pressure problems. Bob Forker (semi-retired rocket scientist) and other ballisticians have reported rifle test pressures as high as 70,000 p.s.i. without visible reaction from primers. Remember those high school science class gas laws, i.e. pressure equals velocity, but bear in mind that:
some firearms have loose barrels which reduce pressure and velocity; and,
some firearms have tight barrels which increase pressure and reduce velocity. See my post on tight Brno/CZ barrels.
Read the first chapter in Ken Waters Pet Loads; and a good manual like Speer #14 before you start. Make notes as you go. I read the Lyman 47th edition from cover to cover at least half a dozen times before I started reloading.
