My experience with the RCBS Piggyback Conversion
I purchased the first generation piggyback about five or six years ago, having never used a progressive system. I like the five position die plate which allows used for sizing, priming,powder throwing,powder check,bullet seating, crimping and then dumping tray.
I remember after initial setup the nylon worm bushing (turns the shell plate at each cycle) wore out quickly. I must say when I have lost a part or needed to replace a part, RCBS had shipped the part(s) at no charge to me which is wonderful.
After reinstalling the worm bushing I applied a little vaseline then some white lube powder (darn if I can remember the name now) and had no further problems with the indexing of the shell plate.
I tried the primer feed/primer bar the automatically prime the brass (in this case 45acp) and found it worked ok if kept it clean but I did not like it because it doesn't clean the primer pockets and I prefer seating the primers by hand, either with a lyman 310 priming tool or my new RCBS hand primer unit that works well.
So, now I size all the cases removing the primer, then to the tumbler to clean the brass, hand prime, then through the press until the rounds are completed. I can watch tv, clean primer pockets gaging the flash hole if I want (not necessary in pistol brass same brand)and then seat the new primer perfectly.
Damaged primers take away all the benefits of reloading precision ammo.
Oh yes a Lee Auto powder thrower works beautifully on this unit. It throws accurate powder charges and the powder checker RCBS die really draws attention to the correct charge, double charge or no powder. The lee powder thrower also bells the cases automatically which eliminates the expanding die and lead bullets will not shave lead when the bullet is seated.
Like anything else, the unit should be thoughly cleaned when needed or it will hang up and strip the worm index bushing. Patience is the main helper here. If you feel the handle hesitate or unit hang up, DON'T FORCE IT!!! This will just cause a multitde of problems
You can pull cases out of the system too without starting completely over if you want to do so.
I just purchased a second original model on ebay and intend to use it for 223 Rem and 308 rifle cartridges. Alse plans to fix the priming system including cleaning of the primer pockets. Hey good safe reloading everyone
