Ok so looking for some input I was thinking of a way to reduce case capacity to make light boolit loads with to reduce charge size but retain velocity. So what I have done is filled a 303british case with zinc, drilled out the flashole with a 5/64 bit and, down the neck with a 7/32. was going to use the lee 314-90 swc and start around 1.5gr tightgroup. If this sound like a terrible idea and bound for disaster I’ll like to here it or any other opinions.
