I was given approximately 300 older Remington Peters 20 gauge hulls and they are probably from the 1960's (see attached pictures). Some are once fired and some have been reloaded once. They have a plastic base and not a paper base and are ribbed. The gentleman that gave them to me said that the Winchester AA wad will not work in them because this wad is a little longer and that you have to use the older Remington "Power Piston" wads in them. Does anyone have experience loading these older Remington Peters hulls? Exactly what kind of Remington wad would I need for them? Any help is greatly appreciated.
