I now have two different primers to load Chedditte and Nobel. My investigation at this point finds the following:
1. Rem factory primer has a .241 diameter and a .292 length
2. Chedditte reload primer has a .238 diameter and a .290 length
These two are close in size.
3. Nobel reload primer has a .242 diameter and a .302 length
So, if I'm just depriming a first reload, I need to figure out which primer to start with. If I use the Nobel....I'm stuck with that hull being a Nobel primer shell forever as it stretches the primer pocket.
Loading with a Chedditte first may give me an option for another primer IF I could ever find them later on.
