If the side crimp is near the mouth, it will cause the mouth to flare outward slightly, inviting hanging up on every edge it passes by when stripping and chambering, not to mention some times being so wide as to drag on the chamber going in. For the times when I used a side crimp, I followed it up with a taper crimp to snug the mouth back to the bullet.
Not trying to start another episode of
Can you top this?, but after many experiments using the side crimp to greater and lesser degrees, I went back to just the taper crimp because
from my experience I got tighter groups using just the taper crimp. My velocity SD went up, but the groups went down. I repeat,
I am speaking solely about my own experience off of both a benchrest setup and using a Caldwell Lead Sled I borrowed from my Dad. If you are going to shoot offhand or self-supported other positions, it will not matter. Go for the tighter velocity SD. Also, the added neck tension will allow you to milk higher velocities, using lighter bullets, from the same amount of slower burning powders. It did not have any impact on faster powders like 2400. I have over 1k rounds of different 450B load experiments through my rifle. Every shot and I mean every shot was over a chrony. May sound boring, but it's what I enjoy doing at the range. YMMV.
