IMR Blue, and IMR Red. The Blue is supposed to be the same as Blue Dot and the Red the same as Red Dot. I use a lot of Blue Dot in 38 Super, 10mm, 40 cal, 44 Mag and a couple of others. I use a lot of Red Dot in 45 ACP and a couple of others. So I plan in the near future to try both the Blue and Red. I have resisted trying any of the new powders mainly because the older stuff I have used for many years, like H-110, 296, 4227, AA1680, AA#9, AA#7, 4350, 3031, and several others are still doing very well and there is really no sense in changing.
