I looked at Cabelas - I could not find a way to tell which sabot they were... If I had to guess I would bet they are 12's. You do need the 24's for the Remington...
To be sure you might go to:
http://www.mmpsabots.com/
and order directly from them... the prices are higher but that includes shipping. You could ask Connie if she knows which sabot Cabelas has - if Del is there he will know for sure.
Another suggestion get one package of the 3 petal EZ loads from MMP - they load the second hurry up shot excellently.
