12 Gauge Shotshell Pack replicas and snap caps

A 12 gauge shotgun shell, also known as 12ga or 12G shotshell, is a centerfire shotgun cartridge. Centerfire shotgun shells were designed in the mid 1800s.

Includes 4 lengths: 2 3/4in (most common, 2.75in, 61mm), 3in (67mm), 3 1/2in (3.5in, 80mm), and 1 3/4in "shorty" (1.75in, 39mm).

Note: Shotgun shells are measured by the total length of the uncrimped/unfolded shell. The actual length of a loaded 2 3/4 inch shell is around 2.4in.
