Let me recommend the crushed rib sabots over the others. They really are 50% easier to load. I almost had to drive a few other types in with a mallet.
And if you give them a call and ask nicely, you can get some samples of a few different types. Or at least they sent me some before I decided I liked them. I'm a round ball only guy now, but if I were to need a sabot, it'd be the crush rib.
