We shot a lot of Pigeons with them. Im not a ballistic expert but they seemed fast to me because when I first shot them after jokers I was missing, but soon adjusted by slowing it down a bit. We shot birds further and further out with them. Ive been shooting for 30years but am no expert, but I can recognise a good performing cartridge on a day when theres lots to shoot at. Melior have a website and had pigeon load on there but heavy loads, and I couldnt see the point when these GTs were so good. We were also getting them far cheaper than Hull or Gamebore could offer.
