Hollow Point

Advantages :

  • Much better expantion
  • Shorter than a Spitzer at the same weight
  • Functions better in multi-shot magazines

Disadvantages :

  • Slightly lower BC (really small difference)

Hollow Base

Advantages :

  • One can produce very light slugs for their length, suitable for less powerful Air Rifles that would normally not be able to shoot slugs.
  • Provide great expansion at the base during firing, ensuring that it seals the barrel.

Disadvantages :

  • Base more susceptible to damage during transport and handling
  • Less BC at same weight compared to other designs
air rifle slug flat base configuration
Flat Base

Advantages :

  • Traditional proven design in the industry.
  • Very accurate
  • Good BC
  • Works well in multi-shot magazines

Disadvantages :

  • Base less susceptible to damage than Hollow Base but more than Cup Base
air rifle slug cup base configuration
Cup Base

Advantages :

  • This design is a custom design developed by Inferno after a significant amount of testing with various base configuration
  • Least like to damage during transportation and handling.
  • Very accurate
  • Good BC
  • Works well in multi-shot magazines
  • Flat inside base to ensure the probe seats it straight in the chamber/barrel.

Disadvantages :

History of the Cup Base design for Air Rifle Slugs

“The Inferno Cup Base design was developed from what the industry normally terms a “Concave Base”. During testing we found that the concave, inside base, caused some probes to seat slugs often slightly skew in the chamber/barrel which negatively impacts accuracy. We therefor changed the normal concave design of the inside base to be flat, ensuring that most probes seat the slugs straight in chambers/barrels. Additionally, we altered the design to include a fairly thicker and rounded rim at the base to ensure that it is less susceptible to damage while handling or transporting. After these changes we termed the changed design “Cup Base” to ensure it is not confused with the traditional “Concave base.
