Flashman2, I am so sorry I am taking so long to reply to this and respond to your kind offer. The Powder Coated 270 would be great to try but as I'm in the UK, it would seem rather excessive for you to post them here. Very kind though it is.
So, as an update, with various things going on in 2019 and 2020 being pretty much a write off for range time and getting to hunting grounds, I haven't done a massive amount of shooting or reloading and what limited chances I have had to do things has mainly been taken up with shooting specific competitions or going out to maximise chances on deer meaning the .44 hasn't come out much except for plinking with cast loads and Unique.
So, I have got an OK shooting load with the 200gr XTP and the Sierra JHC 210gr but as others have said I have some concerns about the impact velocities and bullet performance given how fast they have to leave the muzzle to make energy requirments - (for the 200 gr XTP I reckon this happens at about 125 yds down range, and I'd hope to shoot my quarry inside that distance).
I should have listened to the collective wisdom here and used the 240gr Nosler JSP quite possibly for several reasons.
1) It would seem to hold up better when used carbine speeds (see above and other web sources)
2) Unlike things with the 240gr Hornady XTP and Sierra JHC, the bullet is shorter so needs seating less deep in the case.
3) N110 seems to have been the powder I should have looked to first as a reloading option rather than H110 as rather more flexible
(If H110 doesn't work out I can easily still get Viht N110 here in the UK for the moment)
So, using Noslers data and Gordon's reloading tool for a 20" barrel and 23.8gr (max) of H110 a Nosler 240gr JSP should get me over the energy limit by about 45 ftlbs. In velocity terms, I should be able to shoot about 25fps under predicted max charge velocity. I have some hope I should be making the required ME requirements even with a load that slightly underperforms the predicted max charge. The one area I think that slightly concerns me is I might be getting a low percentage burn in the barrel. I believe a "heavy" crimp from the Lee Factory Crimp die is called for and I will also use a magnum pistol primer to set things off to give best change of full powder ignition.
As I said, if this load isn't giving me the full requirment I will experiment with N110 which seems to possibly give a better results at least on paper with carbine length barrels.
Scrummy
