RE: How fast must they go?
I forgot about those Speer Plinkers, I may try them out too. I just never thought they would be too accurate because they are so light. Thanks for that thought.
P.S. - I hope this post isn't getting people to believe I am just going out, putting powder in a case and seeing what happens. I have yet to do anyload that I could not find in a reloading manual, its just that things interest me, and get me to thinking of what is possible. Thanks for the replies and inputs so far.
