Thanks to all for the kind words - I'm very pleased with the results and will be giving a range report ASAP.
G-man - I knew about the Western Bullet cast bullets but not the new brass being made by Buffalo Arms - thanks! John Henwood's book has some loads too. I wish that I could find the book!!
Also, I need to clarify that while there is no doubt that Mr. Lebman modified 1907s (and provided Thompsons and other modified guns within the law - the National Firearms Act had not been passed yet), he apparently didn't know (it cannot be proved) that he was making them for criminals. He knew Baby Face Nelson and others by alias' and Nelson apparently distributed these to Dillinger, etc. The real question is how many of these modified 1907s were produced? By all accounts, very few; perhaps no more than 4-5?
It ain't like the old days, but it'll do.
