What's the velocity for the red dot?
Next place I would check would be the manual to see what charges it call for, for BE. Then I would do the workup and shoot them over a chronograph and you should be able to see which load gives the same velocity.

Bullseye and Red Dot are going to yield very similar recoil and velocity it 45acp. A good place to start is 4gr. The manuals I have and Alliants current load data all show Bullseye being only 10-20fps slower that Red Dot at max charge with 220gr LSWCs.

Perhaps you would like to travel over to the Alliant site and see what the maker of Bullseye has to say.

My target load is 3.8 Bullseye with a cast 200 gr bb swc out of a Lyman mould.

You may want to bump the Bullseye load up slightly. I typically use 4.5gr of Bullseye with my cast bullets as they are a bit harder than the typical 200gr SWC "swaged" bullets.
Co-competitiors in PPC use the 200gr swaged Delta Precision SWC over 4.0gr of Bullseye (and current male and female semi-auto service gun records are with this load), but they have to reduce the recoil spring to a 12 or 14lb spring for reliable cycling. (The female shooter uses a 12lb as she dosen't present as much "resistance" to the recoil of the load in the M1911).
I use a standard 16.5lb spring and with 4.0gr of Bullseye, I will get occasional failure to feed. However, with 4.0gr of RedDot or Clays, I get reliable cycyling.
The RED Dot load will be getting about 800fps (4.0gr), whereas the Bullseye load will be running ~725fps.
Bullseye is listed as a little bit slower than RedDot and has a "softer" pressure curve. Either have given me exceptional accuracy, however.
Currently, when I use the .45acp for matches, I use 4.2gr of Clays... Gives about 825fps and better accuracy with my "harder" SWC's. (Lee's copy of the H&G).
