A fast and accurate slug for long-range shots. The slug body is made of steel and galvanised for corrosion resistance. The recoil is short and soft, allowing quick re-acquisition for a follow-up shot. This is particularly important for semi-automatic firearms. The slug has a low tendency to ricochet and performs excellently when passing through light obstacles such as grass and branches. After passing through an obstacle, the slug quickly returns to its original trajectory. On impact, the slug transfers its energy rapidly. It does not fragment, so it does not contaminate the meat.
Key advantages:
Lead-free – high accuracy at long distances
Minimal barrel friction
Compatible with all chokes
Maintains trajectory after hitting obstacles
Soft recoil
Reduced risk of ricochet
Powerful impact and stopping effect
Highest accuracy with a 1 mm choke
Application: The Monolit 28 slug can be used successfully both in driven hunts and when hunting individually from a high seat.
Compared to rifled barrels, this slug is very safe in driven hunting. It also offers more advantages in densely vegetated environments where there is a lot of vegetation in the shot trajectory.
