start with one ounce of shot and 70 grains of 2f black...tie gun to tire...attach lanyard to trigger...cap...stand around corner of barn...pull landyard...

after it goes bang,,,inspect gun for damage...repeat three more times, with same load...fire twice in both barrels...

if gun is still undamaged, it may be ok to fire in hand,,,or not...


keep it simple and keep it safe...
