[QUOTE="boomtube, post: 324310, member: 9215"] "If anyone were going to continually run "HOT" loads then I would advise buying a highly expensive lab scale and pay to have it calibrated every month by a professional company." Not necessary. My 1010 is accurate to .1 gr, all the time, every time. That's more than sufficent accuracy for reloading. "If you don't have it calibrated by a professional than your beam scale is no more accurate than a digital scale. " Not so. The 1010 has a standard test weight (mine is 260.9 gr.) and anyone can purchase a set of test weights for a modest price. All I need do is set my poise weights at the correct places, set the standard on the pan and it quickly settles exactly on the mark, just as it has since day one. Electonics drift but mechanicals have ONE SLOW MOVING PART that is ONLY driven by gravity and that does not drift. I fully agree that [U]absolute accuracy is NOT required for reloading[/U] but [U]absolute repeatability[/U] IS. Electronics are rarely long term repeatable, not precisely so anyway. Those tiny components change as they age, especially in the power supplies, and that's just a fact. Rifles vary. Virtually all of mine shoot markedly better when running full bore! So, I'm always certain to load exactly what I plan to load, and no more. I've never found any rife that shots well "loaded down" unless I go to a faster, less than optimum powder.

Gravity seems to be quite reliable tho.

If all that is hair splitting, seems to be some pretty large hairs with clearly defined black and white sides!
