Welcome Bmac. I think you will enjoy using Bullseye, and I won't be surprised to see the 4 grain loads top 1100 fps, maybe 1150+. I have tried/tested 700x, International, WW231, and Power Pistol so far, and have HS-6 and Unique loaded up for testing. So far, WW231 is perhaps my favorite, and really seems a nice fit for 9x18 Makarov with Jacketed and cast. If you might like to try 95 grain 365" Hornady XTP HP's, they expand really well in test media at velocities of 1000-1100 fps. Speer data from #13/#14 really gets the lead out, and even 2/10's grain below their max for WW231/95 grain bullet, I'm getting a very consistent 1094 fps.
I have Blue Dot, and may try to develop some loads out of curiosity, but 9x18 specific data is lacking. Interesting to note, right at the switch over from Hercules and Alliant around 1995, they produced and published .380 Auto data for Blue Dot. This would seem an odd combo, but they did it, with moderate pressures. No doubt 9x18 loads could be developed that would "work" at some level and safely, but there are so many other choices that work so well, I'll stick with them.
Sounds like your carrier is cast from the same mold as mine; LACKING. 1000 Mak bullets weigh about 13 lbs, and fit and are sent for $4.95 in a USPS $4.95 flat rate box from Mastercast... Really great deal on shipping, and only pay what it really costs.
