My thought is that you are a helluva lot smarter than me, and it sounds like you are having some fun figuring out reloading.
I also think that you might find this Forum interesting:

I think Ron is member here, plus a few others, and you certainly have a Specialty Pistol
I went to a bookstore and asked the saleswoman "Were is the Self Help Section?" She said if she told me, it would defeat the purpose.

Yep, Same rwsem there too, although I don't spend a lot of time there any more. Guess I need to sell some of the Thompsons... nah, never mind.
Inside neck reaming is sometimes needed; not certain how much is too much; load down a bit and try it out! The DW can take it and if you have 700 cases, you have more than enough to experiment.
Technically, the glass is always full; half liquid, half air....

have you looked into a sizeing die for the cast bullets? just a thought.
The bullets are sized to .377, the same size as my throats and a half-thou smaller than my barrel. I could potentially size them down smaller, but I don't think I would get as much accuracy from the gun if I did that.
Granted, I am not shooting 200 yards, so a little bit of accuracy may not hurt me.

Got to shoot the 375 finally today, YAY!
Had some issues though. I was able to try my loads as they were, but could only use 3 of the 6 chambers, as the cases were right on the border of being too big. The 3 chambers I did use, the rounds did drop all the way in with no force to seat them all the way. The other 3 (which I did not use) would leave the round sticking about 1/16" to an 1/8" sticking out.
I shot 8 round total, and man did that thing bark. In an enclosed indoor range, it gave off quite a yelp. I was using double ear-pro (foamy plugs & muffs), and it was still a pretty good bark.
The rounds I loaded, which I thought were going to be medium loads, ended up being way hot. I wasn't able to use the Chronograph this time (wish I could have), but all 8 cases showed signs of over-pressure. All 8 primers were flattened out, but none had "primer flow" of the primer entering the firing pin hole.
I also had some problems extracting. The cases all have light rings around them. When I look into the chambers, the chambers are not smooth, almost like there was a little chatter on them all. I think the combination of the over-pressured rounds, plus the rough chambers, caused the extraction issues. I will take some pics tonight of the cases before and after shooting to show the rings.
On a good note, the gun did shot great and was a blast to shoot (no pun intended lol). The cast bullets that I was trying to test performed great. I checked the forcing cone for any sings of rubbing or shaving, and the forcing cone looks clean except the powder residue, which is even all the way around, indicating to me that there is no mis-alignment.
One thing I also noted was that with 18 grains of H110, and the longer cast bullets, I was slightly compressing the powder. Not enough to force the bullet back out of the case after seating, but enough to where if you shake the round, you head nothing inside.
Now, here's where my questions come in. If 18 grains is obviously hot, where should I back down to? Should I back off 20% roughly? About 14.5 grains of powder?
I also need to look into inside reaming the cases, which I already have a plan for, so that's no biggie. This way the long bullets don't expand the cases.
And as to the rough chambers in the cylinder, is there any safe way to polish that a little? Or should it get sent back to the factory? Or should I just down-load my round and see if I still have extraction issues?
Thanks!

Oh, and I did try loading a round with the 220 Grain Hornady bullets. That loaded into all 6 chambers with no issue, as the bullet is smaller diameter and shorter, so no bulging of the case. I did notice though, that the front of the bullet was flush with the front of the cylinder.
To remedy this, Hornady suggests trimming the cases .025 shorter so that you have some wiggle room in case the bullets jump during shooting.
