Description:

Ensure Safe Function Testing with Inert Dummy Rounds

Introducing the CENTERFIRE RIFLE DUMMY ROUNDS by GENCO INC. – specifically designed for the 338 REMINGTON ULTRA MAG. Each box contains 5 expertly crafted dummy rounds that mimic the dimensions and weight of factory-loaded ammunition.

Product Description

Manufactured to exact specifications, including diameter and length dimensions, weight, and balance of factory-loaded ammo, these DUMMIES possess the necessary characteristics for reliable checks on magazine feeding, action timing, extraction, and ejection across all firearms. The use of these dummies is the only professionally accepted and safe method to verify gun functionality; live ammunition should only be used during actual test-firing on the range, and only after confirming the firearm's operation with DUMMIES.

The very reasonable cost per DUMMY serves as an added incentive to incorporate them into your regular testing routine. Their distinct blackened case makes them easily recognizable as DUMMIES, making them an ideal and safe tool for sales demonstrations. They are particularly beneficial when showcasing the operational features of specific firearms or during gun safety instruction classes, as they completely eliminate the risk of accidental discharge.

The Catch Up Pak contains 1 each of the following calibers:

  • .17 MACH 2
  • .17 HMR
  • .45 GAP
  • .480 Ruger
