I have recived my copy of loading slugs from BPI It has only 2 loads for slugs in 10 gauge and they seam to use a 12 gauge slug with two raps of teflon tape that is also sold by BPI but at lest they give me the type and number of wads that go into loading it. It just seams odd that you would use a 12 gauge slug and not one for a 10. When I get done using the powder that I have now I will get the powder and slugs that it tells me to and try them.
