This is all very interesting, indeed. Seems like PB's are something you either love or hate. I have a friend who kept telling me all season, "I think I'm going to stop using those Powerbelts - they're designed to blow up on deer." But he killed 6 deer with them this year!
I bought them because I couldn't find anything else I could get down my barrel - at least not without at least a minute of SERIOUS effort. I didn't get a chance to shoot a deer this year, so my opinion is still in the theoretical stage.
Does anyone know of a bullet/sabot combination of about the same outside dimensions of a Powerbelt? From what everyone says, they are obviously slightly smaller - but how much smaller? I guess I need to spring for one of those digital calipers to find out for myself.
Keep the information coming; it's really helpful.
