This slug was designed by Nick Nielsen specific to the Huben air rifle. It is made to chamber in the auto magazine and seat nicely into the 19 round magazine. We have shot these slugs with good accuracy out to 200 yards.
Our best groups were about 1 inch at 100 yards and ragged hole at 50 yards. Out to 200 yards we were shooting steel and could easily hit our targets with confidence.
One thing we have learned with this gun is you need to play with the pressures and really tune the gun for the specific bullet you want to shoot. With the right settings this bullet and gun combo is awesome.
THIS SLUG IS FOR .223 AIR RIFLES AND THIS ONE WAS MADE FOR THE 2018 VERSION OF THE 22 CALIBER HUBEN. IT WILL NOT WORK IN MOST AIR RIFLES UNLESS YOU HAVE A .223 OR .224 BARREL!
