I don't reload, but wonder if anyone knows if the 9mm browning long uses the same dies as a 9mm? If I'm right the only difference between the two is case length, 9mm = 19, & 9mm browning = 21. plus powder loads. I know you can't interchange these cal., but is just the seating of the bullet that makes the difference, besides the length of the case. I have about 400 1942 Swedish mil loads that I want to possibly reload and want to know if I can use 9mm dies? I hope I'm clear in my questions because I don't reload and may not know what I'm talking about. I also found new 9mm long loads on-line for $15.00 per box of 50, shipping extra, (being in Ma. have to find FFL to take them), @ $.30 ea would it be worthwhile?? Thanks for your time, Arlie
