BTW someone asked why I was using big 3.5" 18 ball shells instead of the standard little buckshot loads.
The answer is because I can not legally use a rifle or slugs in some places and must use buckshot...despite fairly open country whick offers many long shots.
I wanted maximum range, and my thinking was that 18 balls would give greater odds of putting lead into vitals than only 9 . . . assuming that both loads patterned equally.
But while I am talking range . . . does anyone know at roughly what range 00buck no longer has the penetration needed to reach vitals?
Each pellet is so light and slow, that I wouldn't think it to be very effective, even point blank; if I was just looking at the #s on paper and hadn't seen real world results.
