Finally I've finished it! Video in English. H&N sport new slugs ballistic coefficient calculation and comparison with .22lr ammo + Russian heavy slugs and the very best my new experimental slugs with extremely high ballostic coefficient (>0.2 RA4 drug function). First accuracy shooting at 100 meters (110 yards) distance.
