I'm looking to buy a case or two of buckshot for blowing up watermelons and so forth and I was checking out some Sellier & Bellot. Word on the street is that their 2 3/4" shells are normal length after they're fired but are crimped in such a way that they load like a 3 inch. They make a 12 pellet shell and a 9 pellet both 2 3/4" and obviously the 12 pellet is going to be longer but what about the 9 pellet? Probably a stupid question but some things I've read had me wondering and I don't want to end up with a case of it and find out I don't like it. I've used their 9x19 and it shot great so I have no doubts of their quality BUT I don't want to have my magazine capacity reduced. I like the clear hulls too.

I've also considered Estate and Rio Royal buckshot. Both have nothing but positive reviews on lucky gunner and Cabelas. Thoughts?
