You're on the right path, just got to get the combo right.

I've got one too, with all the same components. The 365gr BACO (cast with 25:1), Swiss 1.5. Federal Large Pistol primers. I'm loading 49gr with a 30 thou veg wad drop tubed. I don't have the overall length handy, but basically there are 2.5 lube grooves outside the case mouth. Compression was minimal, guessing but I think it might have been about 60 thou.

I haven't done a lot of testing (so really I'm not much use to you) but that combo seemed to shoot quite well out to 500. I was basically hitting exactly where I aimed and sight adjustments were true. I was dotting the rams at 500. 

I used SPG lube and it was excellent for cleaning and shooting with blow tubing between shots and cleaning after a run of 10-15 shots in silhouette. I have done another round of loading using a home made lube of (I forget) but it was Crisco, Bees wax, lanolin. I got a very small amount of leading and a little more clean up between shots but I don't have any more SPG.

I've tried 50gr of Wano FFF and the accuracy at Turkey's (385m - only distance tested) didn't seem to be there so I need to do some more testing with that powder, but its not as nice as Swiss.

I'll be shooting a match tomorrow with the load of 49gr of Swiss No.1.5, home made lube so will see how it goes. I want to bump up the powder charge to have a bit more legs at rams so when I get a chance I want to try cramming some more powder in the case. With 49gr, I'm "just" ok on the ram knock down. I've rung a few.

Wish we could get black powder easier. Swiss is non-existent most of the time here in Australia and supplies of Wano are intermittent.

I'm keen to see what the responses are here as I have a lot to learn. I like the rifle. The set trigger works its way loose if you don't loctite the adjustment. On my rifle the wood to metal work fit was very, very disappointing. 1.5mm gaps around the tangs. I bedded the rear stock and I also removed the awful varnish finish, stained with a walnut stain and finished in tung oil for a better look.

The Dan Theodore 38-55 'Money Bullet', shot in a 1:12 twist bore has to be seated so the case mouth is at the 2nd driving band up from the bullet base.
Further, the reload should not be crimp - just remove the bell on the case mouth.  I also would increase the powder charge up to 57grs Read the attached text
Good Luck

Thanks for this information guys,
The bullet casting I did with a 1-20 alloy
The bullet comes out the mould. 3795
So I shot it unsized with SPG grease
Have to say that my brass is new and measures not the full 2.130 lenght now
I did not realize I could compres the powder as much as.250 th and 57 grains
Gonna try it out

sss shooter,
how much powder compression you have on the Baco 365 money with 2f powder

hello,
I did some test last weekend with different loads on target 330 yards distance.
I tried also the 57 grain Swiss 1 1/2 load, but that one seemed not to work for me,I shot 9 shots with this load, only 3 were good the others spread out.shot also with 47 grains FFF swis, did very well at 110 yards and not bad to on 330 yards;gonna try next time with 47 grains 2FF loads
