for reloading at matches, you can set the RCBS to auto and it will start the charge when you set the pan on the scale. I have altered 2 pans so that they weigh exactly the same. I set the 2nd pan on the scale while Im dumping the 1st. I also put in the codes to speed it up. It works great for loading during matches when the relays are 30 minutes apart. Ive had mine over 10 yrs. Most benchresters use them. Mine is very accurate but when it does run a tenth over, (not often) I just dump it back in the hopper. I have used VV133, Australian 322 (no longer available) xbr8208 and the original 8208 as well as other powders without issue. I made a folding box to set mine in at the matches to block the wind. when Im not loading in the trailer. Good luck
