Have a very old Redding scale. Don't know how old, but guessing by the original box with a price printed on it of $11.95, it's quite old. Maybe from the 20's or 30's? Was purchased with an old Champion 201 press and a Hollywood Gun Shop throw. Anyhow, used to reload some years ago. Mostly 30-30 and 30-06. Some .357. Getting back into the shooting sport and have recently purchased a .243 that i'd like make some reloads for. Upon removing the scale from the box, found that the two calibration nuts on the end of the scale are loose, therefore, concerned that the scale is out of whack. Tried weighing some hornady bullets. The scale after being zero'd empty (by further moving the nuts) weighs about 2 grains low when weighing a new bullet. What would you recommend?
