12_GA_Traditional Paper n°8 32 grams

This loading is an Alex's idea. It was tested with great instruments.

This cartridge is loaded with 32 grams of shot (italian size n° 8).

This loading is a classic loading with paper case, felt wad and round clousure, it has great performance as You can see in velocity and pressure data but it does not go over the security range.

It can be used for little hunting but if You change the size of shot lead it can be used for pheasants, rabits or others.
