No, the trick is to use the first (this bullet only has one) drive band as your seating depth/crimp ring/cannelure.



Don't bother playing with seating depth, load up powder charges until you find pressure. If the accuracy is not there, either you barrel twist is too slow or try another powder/more neck tension.

All factory ammo is made to a spec of seating depth, yet it suits the majority of firearms (if the ammo is good and firearm in spec).

Don't burn components needlessly.
