I tried some loads this a.m. in my new KKM 6" barrel. I loaded 10 rounds of 11gr. of Blue Dot and also 10 rounds of BD 11.5 gr. behind a 165gr. JHP bullet. I chronyed both of them . They 11gr. was avg. around 1310fps the 11.5gr was avg. 1360fps. The strongest loads so far in my Gen 4 20. I love the KKM barrel, looks like the brass hadn't been fired, no bulge, no pressure signs at all.
Blue Dot is a good powder, I might try AA#9 or Longshot, but Blue Dot isn't bad at all, doesn't meter like the AA powders, but a strong propellant nonetheless.
Thanks for the info.
