Thanks for the post Phil. That was an interesting read. As far as the powerbelt falling out of the barrel, as in any slug, powerbelts are not going to work well for all barrels. My slug of choice is the 300g hornady xtp. I have read numerous shooters say for some reason the xtp is not for them.

It all gets back to knowing what works best with your own rifle and the conditions the rifle is going to be used. That too is what makes muzzleloading so much darn fun.
