6.5 Grendel reloads pass chamber checker, but....

[Old Bob]

For setting shoulders back for different chambers of the same caliber, you need one of those Redding Competition Shell Holder sets. It has 5 shell holders of different thicknesses to customize the shoulder set-back. You don't need to reset your FL die whenever you reload for different chambers of the same caliber. Set it once on the thickest holder & forget it.
