Not exactly light loads there! I do have a little 4227 I could play with.
On the "twins" question, I figured if it happened to have a twin, there might be data for that other powder out there that I could look up.

Started playing around with AA#9 today, put 22gr in a case and noticed it only fill's about 1/4 of the case! the no-compression full load is about 31gr with this 400gr bullet. This had me concerned that 22gr was too light. subsonic mentioned not going too low with this powder, so I decided not to load them until I did more research. I don't have a 475 to see how much these charges fill the cases.
Just curious of anyone's thoughts on this.

By the way, I did some more shooting a while back.
440gr Leadheads WFN-GC over H110 is the standard here. Very accurate even with the starting load and I've heard it only gets better. I'm new to full-caliber guns so the recoil is positively life altering. But I'm starting to get the hang of it, a little.
Loads of 4227 under the 400gr Missouri bullet works slug shot fantastic and right to the sights. Much more pleasant than the 440gr load.
Using 2400 under a 330gr Dardas RNPB bullet also shot well, but six or more inches low at just 15 yards! I think I'll try this bullet over unique and see how that works. Maybe slowing it down will bring it up a hair.

Sean, what is your 440/H110 load if I may ask? Whit, I've been shooting the "recommended" load of 27.0gr H110 under the Leadhead 440gr bullet. This is the listed starting load in the 500WE and elsewhere. Yesterday I made a batch using 27.5gr H110. Don't expect any real difference, just working up slowly. I'm shopping for a scope that can live on the 500 so I can start getting some more meaningful accuracy results. Doesn't help that my most convenient range thinks handguns are only good out to 15 yards! They won't let me shoot a handgun at 50 yards without a scope! Not to say it didn't happen a time or two. This gun came with some Buffalo Bore JRH ammo, the 440gr @ 950fps light load and those were also very accurate.

I put an Ultradot 30 mm sight on mine. I also used 30mm Warne steel rings. I like the square notch over the round pins for weaver type bases. It holds much better.

As per Whitworth's recommendation for the ultradot I found one used at my local gun store and put it on my BFR in 500JRH. Takes a lickin and keeps on tickin. The red dot in a tube sight is much easier to pick up than the red dot in the reflex type trijicon rmr I had been using. Cheaper too.
