[QUOTE="shortgrass, post: 1654770, member: 24284"] No false shoulder needed if head spaced correctly. The Ackley chamber should be .004 to .006" shorter than the parent cartridge. The "GO" gauge becomes the "NO-GO". The distance from the bolt face to the neck/shoulder junction in the chamber is the 'critical' dimension. The .35 Whelen brass should be longer from the base to the neck/shoulder junction than the bolt face to the neck shoulder junction in the chamber. That will cause some resistance when closing the bolt. The idea is to force the cartridge case to expand at the front, not in the rear, head area. [/QUOTE]
