I am sure that as most of the rest of you do, I pick a particular bullet I wish to use, and start working through the various powders listed in the loading manuals until stuff starts to group up with reasonable velocities. Primer tinkering is left to the fine-tuning stage with me. So-called accuracy loads are only an indication of what may or may not shoot well in your particular rifle with a degree of dependability. I personally have never found one to be an adequate substitute for good, old hand worked load development. I also agree that many guns seem to shoot best with mid-range loadings, and I own several that do just that. I have, however, recently worked up a great load for a new gun, and it loves max load. Just goes right back to what we all have known and said for years about rifles being entities unto themselves
Have I expounded enough?? Methinks so.
