I haven't noticed brass lasts any longer with taper crimp. Most of my failed .38 cracks more down the middle than just the neck, and it takes awhile to do that.

You might consider the weight of the gun if you try it. My 8" 686 won't pull the bullet on a lead .38 even if you don't crimp it at all, but alloy stubbies are notorious at pulling bullets under recoil.
