How to tell if primed brass has been neck sized or full length?
I bought a single shot target rifle that came with 80 pre-primed cases. The cases came sorted by weight and carefully marked on the boxes with the date they were fired and other notes. The previous owner was very meticulous, but I don't have access to him to ask. The only cases I already have in that size to compare them to to are also already fire formed in another rifle and neck sized. Is there a simple measuerment I can take that will give me an indication?
COAL is not an issue since this ammo will be used exclusively in this rifle, and is is a single shot action. I just don't want to put a lot of effort into working up a load in FL sized brass, only to have to tweak it later. I plan on only neck sizing going foward. The fire formed ammo I had from another rifle chambered without issue and fired nice groups. It is .001" off the lands in both guns, so I expect the load development to go quickly.
