Not sure if there are any actual advantages. The star crimps are easier than the roll crimps, which are far more time consuming. If you have a lot of time on your hands, go for it! With the 12ga roll crimps there are actually a large number of components to be found, especially from BPI. Cheddite hulls work very well for roll crimping. Another issue that I have with roll crimping is the availability of components. The majority of roll crimps I am looking at use fiber and cork wads rather than the usual plastic wads. I use an old Sauer & Sohn 16ga double and want to use roll crimped shells exclusively, but with the lack of shotgun powders it is a bugger!

I should also ask, how are you reloading your shot shells now? (Just trying to understand why an Italian loader would improve loading so much!) What type of machine are you using? If you are using a Lee, I can sympathize. I made the mistake of purchasing a Lee Loadall to load 16 and 20ga shells. Loaded 1 box of each, packed the loader back into its box, and went out and purchased a MEC Sizemaster (I already use a MEC for my 12ga loads.)

I have to say I'm impressed. The Italians have taken shot shell reloading to a whole new level than what I'm used to! The availability and differing types of progressive machines and components for the 16ga are something else. From what I've been able to see, roll crimping is not used in Canada at all, unless you are producing them yourself.

Actually, with a small inexpensive loading machine like the RCBS Mini Grand and a Cortini & Pezzotti T2 roll crimping tool http://www.siarm.com/product_i..._168&products_id=306 one could reload any 12ga shotshell length to look and shoot equally or better than factory shotshells either with fold, roll or folding roll (a combination of 8 star fold and roll crimp where you can see what is in the hull, similar to ordinary roll crimp, only deeper.
simce I have some trouble crimping 3" shells I roll crimp them in a drill press.....yes a bit extra work but the number of 3" shells I shoot in a year it's a small issue to me.
This much I will say.....it's the last time you will shoot that hull as after firing a rll crimped plastic hull it's not to be reloaded again.....the case mouth is destroyed.

Roll crimping needs less than 1/4" hull to be good, a star crimp needs @½". I know this because i shoot an old BP shotgun with 2½" chambers and need powder space bad! And that 1/4" is @ 20grains of BP.
Using roll crimping and a clear over shot wad/fracture disc it is easy to identify shot size in allready loaded hulls.
