Gander , 1" rule ?????????????? min or max . bullet length ??

Any other unique rules I ought to know about .

I tried a few sabots Idon't recall brand they were great the first shot but rod benders after that.
The bullet looked like an egg sinker though ,a package deal for a half a day's work .

Any one tried a "bullet shaped" bullet had a friend that had some about 10 years ago for sabots they were a custom
thing he's lost the info .
