[QUOTE="Mikecr, post: 1971348, member: 1521"] A better plan is to throw away the Hornady and live with what you have, or,, throw away the Hornady, pickup a v-block type runout gauge, and discover what your runout actually is. Then you can figure out whether your runout matters, and if so, go after the root causes. Forget concentricity, as it's a misnomer for eccentricity. A concentric item holds the quality of low eccentricity. Concentric is w/resp to centerline. Where it is concentric, it has been centered. This rarely applies to chambered ammo at rest, and is in no way beneficial. The old notions that you can get bullets pointed true to barrel centerline are pure rubbish. Straight ammo holds the quality of low runout. If it were centered it could also be described as concentric. This is the quality to reach for, in that straight ammo can rest stress free as chambered. When the bullet is neck released on firing, it will bore communicate with a quality established through full seating testing. When you force a concentric condition with high runout ammo, you have not addressed the chambered condition of that ammo. The question then is; do you have enough chamber clearance for this crooked ammo to rest stress free? [ATTACH type="full"]211934[/ATTACH] [/QUOTE]
