I bought a used Piggyback II with Rockchuker and Uniflow powder measurer online more or less as an impulse buy yesterday. I probably paid more than I should have. It is what it is in 2021. This is will be the first progressive I have owned myself. I have used other progressive flavors owned by other people.
In reading about the Piggyback, it seems people love them or hate them. The plan is to set it up for 9mm and leave it.
Given that this is used, are there any parts I should be taking a close look at when it arrives? I have read there is a nylon bushing that tends to wear. Are replacement parts form RCBS still available? Are after market parts for this a thing?
