3D model description

HEAVY (2,9g) FuckYou-Slug
to ad 8mm round balls (you can get them cheap on ebay;-)


The T23-67 is another of our heavy designer projectiles for the HDR50 CO2 revolver, which sets new standards.

The bullets punch beautiful round holes into your cardboard disc or leave a lasting message on the target.

Due to the slanted tails in the rear area, the T23-67 FuckYou-Slug is turned in a fast, longitudinal rotation when shot. As a result, the projectile is stabilized in flight (similar to pellets or bullets fired from a rifeled barrel). Thus, Slugmaker's best T23-67 fly much better straight than other projectiles - even at further distances.
Due to the fast rotation, a very straight trajectory, penetration effect and - if used for self-defense - painful hits with memory value is guaranteed.
The projectile has a steel core (ad 8mm round balls (you can get them cheap on ebay;-)), which gives it the relatively high weight and head load.

Optimal bullet - weight for strong HDR 50 CO2 revolvers.
The T23-67 Slugs are specially developed for CO2 revolvers in the cal.50 such as the Umarex HDR50 or the Roscoe.

Slugmaker's best T23-66 Slugs are therefore ideal for sports shooting and home defense (with memory effect;-))

3D printing settings


PLA works best
layer: 0,2mm
infill: 50%
speed: +-50mm/s
no supprts!

In order to create an optimal adhesion to the printing bed with PLA, try to level the first layer rather low.

For the best possible quality of your slug-prints with no rework, it is recommended to always print several slugs in one pass, so that the parts have enough time to cool down until the hot nozzle travels the next layer over it.
If you just wants to test a design, firstly print best 6 pieces. With a printing plate of 20x20cm (f.e. Anycubic mega or Prusa MK3) it is possible to place approx. 100 cal.50 slugs.
Attention - only for personal use!
