I think the Harvester Short Black and the MMP HPH 24 will cover most bullets you want to shoot. My Endeavor loves the short black sabot and a T/C shockwave. I've also had good results with the new Hornady FTX .430 265 gr. bullet and the regular harvester green sabot. I'm also going to try the MMP HPH green sabot. I think it will fit a little tighter.
