Seen post about a 50 bmg round made from a 7mm mag case that was filled with lead shot. Did quite the number to a row of milk jugs.
I was thinking I would take a 40 S&W case fill it with #6 shot and cap it of with a 8mm "Airsoft" plastic pellet. Measured the nose of the bullet coming out of the CH die and as I remember it was just small enough that I think it would work.
May be fun to see what performance would be like.
Wait.... just started thinkin, not sure how it would swage out to propper size unless the shot was totally compressed inside.
Well it's a fun idea anyway I may just try and see what happens
Good shooting,
Brian
