Remington is the leader in making hulls specification changes. By changes, note we are talking about types of plastic and the internal base heights. Colors of the plastic (if they are plastic) hull bases may vary while the height may be the same, or NOT!

Internal heights of the hull base are important to the reloader as this impacts hull CAPACITY.

Phone rings… "The load doesn’t fit." Curmudgeon's first question in response is: "What hull are you working with?" You tell us, "Hey, it’s green." And so it is… The Curmudgeon prepares another pot of coffee and prepares to explain.

Remington engineers their hulls to fit their load specifications. In looking at an array of Remington hulls which have cut-away views, we can measure their internals overall length and base heights. We find that we have five different Remington 10-gauge hulls.

• All are green.
• All have slightly different overall lengths.
• Internal bases are white, yellow and three are black.
• All hulls differing in base heights and overall length.
• Measured down from the hull mouth to the base we get:

3.00" – 3.05" – 3.12" – 3.20" & 3.20"

The 12-gauge hull grouping is more diverse. The reloader becomes distraught with these same appearing but quite different hulls. The inclination is to shy away from working with variable field hulls.

The outstanding hull for reloaders from Remington hull manufacturing is the Remington target hull. The "STS" made in vivid green and the "NITRO 27" in brilliant gold are superb hulls for target reloading. By design and capacity - this is not a field hull.

Promotional loads & hulls
Other Remington target hulls tend to be special-run promotional loads and hulls. These hulls can and do vary in plastic content and internal capacity. These hulls may be made of a "stiff" plastic to accommodate a certain factory recipe and will run higher pressures in otherwise "standard" reloads. Promotional load hulls are ignored for reloading because these hulls are short runs and frequently altered.
