I was looking up load data for my 357 magnum in the Lee Modern Reloading Manual 2nd Edition recently and couldn't find any mention of the test barrel used in developing their loads. I checked several other calibers and same thing. This is the only manual I've seen that doesn't list the test barrel (unless I overlooked it somewhere). Can others confirm what I'm seeing or correct me if I'm wrong? I've often read that the test barrel is a critical element in determining a safe load because pressure can change significantly from barrel to barrel based on length, twist, type of rifling, cylinder gap, etc., which would make this a huge omission from the Lee manual if true. Just curious if this is true of if I just need new eyes. Thanks.
