Worst day's shooting ever. Decided to use conicals for the first time with my Investarm .45 'Hawken'. Half my caps didn't go off, and half my shots 'keyholed'. Had to take the nipple off several times to clean the spark channel, and despite cleaning every 3 shots had three hangfires. The only good thing to say is, of the 12 or so shots I managed to fire before I got ****** off and went home, at least they all hit the card. Distance 50 metres.
