I have tried to post this a couple of times but this site seems to be having some problem. I cannot even bring it up without trouble. Anyway; I have only shot nine shots of BM3 over a chronograph. Of the nine shots eight were within 50 fps of an average around 1950fps. One was about 1875fps and I don't know what caused that. I have wider variation with 777 or Pyrodex. Clean Shot is pretty consistent. I will not be using the chronograph Saturday as it is at the range and difficult to set up there. I will try to get more over the chrony later in the week when I can get a bay at the Practical Pistol range. Weekends are too busy. Since I last shot I have lapped my barrel and that should help to make the results more stable. My Omega does not have a lot of bullets down the barrel and I think the lapping was required to make loading more consistent.
