1.What is the measurement from the base of the fired cartridge case to the 'ring' beneath the shoulder?
1.743" from base to the first ring -below the shoulder -this ring is only a semi-circle and does not complete a full circle -I would say about 160 degrees
2.What is the measurement from the base of the fired cartridge case to the present shoulder?
1.831"
The fired case has the following measurement differences.
Base to Shoulder :Eley 1.825" -Fired -1.841"
Shoulder diameter:Eley 0.455" -Fired -0.452"
Distance between shoulder and neck:Eley 0.075" -Fired -0.057"
Base Diameter: Eley 0.468" -Fired -0.467"
The second ring is close to the cartridge mouth is totally circumferential. Its an indent in the cartridge wall that looks superficial.
3.Compare measurements of a raw Quality Cartridges case to one you have loaded to see if you've pushed the shoulder down. Also compare an unfired cartridge to the Eley drawing.
It looks like the Quality cartridge is pretty near the drawing by Eley. It seems like the fired cartridges did expand a bit.
4.Also, we haven't seen any photos of the rifle. Is the barrel original
the barrel is definitely original
