Solution: Don't go max on the powder charge, find a loading that operates your semi auto pistol (not so important with a revolver), and use and/or mix your primers, then just go shooting! Whether you are deviating even 50fps with most cartidges will mean very little at pistol ranges. I have found 230gr .45 acp bullets shot at 800fps hit about the same as those loaded to 850fps. It should be the same with most cartidges. You can get obsessive about every little thing when reloading, like COL, case weight, handweighed powder charges, etc, but shooting two hands at 0-25 yards, all of that makes little difference (translated: in the real world). Rile shooting at long range is another story, but normal handgun distances, not so much.
