There is some evidence to suggest that the roll crimp produces less desirable groups than the star crimp in bird shot loads at 40 yards.
I can’t imagine a discernible difference with 00 buckshot.
You may find that the loaded roll crimp ammo is slightly longer than the star crimped ammo. This might make a difference in reliable functioning of your gun but, you’d have to test it to find out.
I’d probably buy the star crimp ammo if prices are comparable, otherwise I’d buy the cheapest.
