20/67,5/3,05mm steel brok 24 25 ks

Product detailed description

The Hunting Act No. 449/2001 Coll., as amended, prohibits the use of "lead shot cartridges" for hunting waterfowl with effect from 31 December 2010.

Cartridges for calibre 12/70 with shot size up to 3,3 mm and for calibre 16/67,5 and 20/67,5 with shot size up to 3,05 mm are cartridges intended for all shotguns of the given calibre, which have successfully passed the piece verification and therefore have a valid test mark stamped and of course are in good technical condition;

The 12/70 and 12/76 ammunition with 3.81 mm shot size is intended only for weapons that have passed a special pressure test and are marked with the appropriate test mark. The plastic protector (basket) is of a different design than that for lead shot. The basket for steel shot has thicker and longer walls, thanks to which it separates the cartridge from the barrel during the entire movement of the bore;

Therefore, if all the manufacturer's instructions are followed, barrel damage cannot occur even with older weapons. When using ammunition for which a higher pressure test is not required, any hardening can be used. For weapons that have a higher pressure test mark, you can use any hardening for calibre 12 up to a shot diameter of 4.0 mm and for calibre 20 up to 3.30 mm. If larger diameter buckshot is to be used, the bore must be 0.5 or less.

Steel shot is made of a material that has a lower specific gravity than lead, and therefore loses velocity significantly sooner and thus effective range. It is important to remember that the distance you are used to hunting will be about 1/3 shorter. If you have, for example, a 12 calibre shotgun without a higher test, you can use, without risk of damaging it, the largest shot of 3.30 mm diameter. The ideal distance for a reliable kill of a duck will thus be about 20 m.
