Has anybody tested Tugsten Super Shot or UNA 18 super heavy pellets? I have not yet, but hunting friends have shot foxes, hares, roedeers and so on at 50-70 yards distances with 2,5mm (No. 7)pellets. Their penetration is unbelievable and patterns very tight and symmetrical. Hunters load TSS/UNA cartridges themselves, because factory loads are not available (in Finland). They use double wads to protect barrels against scratches of hard pellets. Open chokes are suitable (super tight patterns)and there are special made screw-in chokes for TSS/UNA 18.
