Just as a side note, the term gas checked Keith style bullet is an oxymoron in view of the fact that Elmer Keith had an extremely intense dislike for gas checks and never designed a bullet which used them. As mentioned above, the true .44 caliber Keith style cast SWC is the Hensley & Gibbs #503 or the later Lyman/Ideal #429421 with square bottom grease groove and three equal width driving bands. Keith found that properly sized and lubricated cast bullets require no gas checks at velocities of 1.600 fps or less and this holds true to this day.

I have never cared for Blue Dot as it seems to start to do unpredictable things as you near maximum loads. That said there are a few folks who just love it but they are a relatively small minority. I use it (very carefully) for full power 10mm handloads and that's it.
