Thread: What in the world?

Greetings Moa Hunter and Dicko,
Yes Moa Hunter the plunger will hold the cartridge forward in the chamber on rifles with ejector plungers. However primers back out on my low pressure loads in my scoped .303. This rifle does not have a plunger ejector so the case being forced forward in the chamber is independent of ejector type. Yes Dicko the belt would hold the case to the rear of the chamber if the belt and chamber recess tolerances were tight. Unfortunately they are not held to tight tolerances, especially on cases that have a substantial shoulder. In practice the belt does not help. If the case is sized just enough to chamber another problem can develop. Minimal sizing can leave an unsized portion of the case body just in front of the belt with hot loads and some makes of cases especially with cases fired in another chamber. Even with the die hard down on the shell holder this may not be resized which can lead to hard chambering. Some of the die manufacturers offer a special die just to remove this bulge. A friend with a .308 Norma Mag used a .300 Win Mag die with the case sitting on top of the shell holder to remove the bulge. Unfortunately the belt on bottle neck cases can cause more problems than it solves.
Regards Grandpamac.
