Early ammunition had a 4-digit year with the first 2 digits (thousands and hundreds) at 9 o'clock and the second 2 digits (tens and ones) at 3 o'clock. Ammunition with an E at the 12 o'clock position (which stands for Ersättning, or "Substitute") have a bimetallic cartridge-case (brass-clad steel) due to wartime economy measures during World ...
The ammunition was copper-washed steel-jacketed bullets with copper-washed steel cases. (This makes it magnetic – so it may fail the BATF magnet test used to detect illegal semi-armor-piercing and armor-piercing steel-core penetrators). Some are found in brass cases, and are readily identifiable after firing, as these cases are still Berdan ...
It held 20 × 25-shell cartons (500 total shells) of 12 gauge ammunition and weighed around 65 lbs (Dimensions: 15" Length × 10.375" Width × 9.75" Height; Volume: 0.88 Cubic Feet). Guard shells had either a brass base (base only) with a full paper hull or partial brass case (1" long) and a long paper hull.
The head of a brass case can be work-hardened to withstand the high pressures, and allow for manipulation via extraction and ejection without rupturing. The neck and body portion of a brass case is easily annealed to make the case ductile enough to allow reshaping so that it can be handloaded many times, and fire forming can help accurize the ...
Pinfire became obsolete once reliable rimfire and centerfire cartridges became available because without a pin which needed aligning in the slot in the chamber wall they were quicker to load. They were also safer because they had no protruding pin which could cause the ammunition to accidentally detonate during rough handling, particularly of ...
