i see that the bullets are different for the 357 sig and the 357 sig LE. i know the LE is suposed to be about 25 fps faster but that shouldn't require a different bullet. the only thing i can think of is the more requirement for penetration on the LE round. on pics that i have seen the 5 petals on the standard round seem more extended than the 6 petals on the LE round when shot into balistic gel. the LE round petals look rolled back. it looks as if the standard round may be a better sd round for ccw. any info on these from those in the know will be appreciated.
