I have played with cast rounds a lot. Drilled them out.cut them down. and loaded them backwords.

When I shot them backwords. The bulet tumbled in the air and I could not get any kind of pattern at all.At 50 yards I had a 12" or more spread.

I do not think it is the best for every one to try this at all.But if people did not try things we would not have all the goodies we have now:}
