Graf also sells 2.5" primed Cheddite hulls, including paper!
I use the same trimming method as GLS except I install a round head screw in the end of the dowel to allow for trim length adjustment for different hull base wads.

I made one with a screw in the end so that it can be adjusted - it works great.
RST hulls are Cheddite. Also, I sent a group of hulls to Tom Armbrust to test - all components in the low pressure load were the same except the hull. In 16 gauge the RST, Australian Winchester, Nobel Sport, B&P, Fiocchi and Federal plastic with paper base wad all produced pressures that were essentially the same and I now treat them all as interchangeable with that particular load. The Remington RGL hull produced significantly higher pressures as I had expected it would.
