Description:

Ensure Safe Function Testing with CENTERFIRE RIFLE DUMMY ROUNDS

Manufactured by GENCO INC., these 338 Winchester Magnum Dummies are designed to meet exact specifications, including diameter, length dimensions, weight, and balance of factory-loaded ammunition. These DUMMIES provide the proper functioning characteristics needed to reliably check magazine feeding, action timing, extraction, and ejection for all firearms.

Why Choose DUMMIES?

Instead, these inert dummies offer a professional and safe method for checking gun functionality before actual test-firing on the range. The cost-effectiveness of these dummies provides an additional incentive to incorporate them into your routine.

Key Features:

  • Distinct blackened case for easy recognition as DUMMIES
  • Ideal for use as a sales aid during demonstrations
  • Eliminates the risk of accidental discharge
  • Perfect for gun safety instruction classes
