oftentimes you'll find that even two guns of identical manufacture will have different preferences in ideal loads. and possibly two very different safe max loads. you may well find that both guns like the same loads - but you wont know thats an accurate statement until you test it.
start low (published min) and work up loads in 0.5gr increments w/ 3 cartridges per weight until you hit max with both. examine your brass as you work through this ladder of loads. watch for pressure signs, learn to read your primers. i write the charge weights on the side of the casing before i load them so they're easy to keep organized. your tumbler will take the sharpie off for you when you clean them up.
one thing to note about h110 - be cautious as you approach max. this is a powder that can go from 'hey that looks alright' to 'whoah... thats scary' fairly quickly. i dont want to make you nervous, just properly attentive. It'll let you know before it gets into dangerous territory. its just not a powder thats known to be happy about being overloaded into a case.
here is a good read on understanding what your brass is telling you as you shoot it during load testing.

Did they dump all their energy inside the deer and not pass through? I ask because if your solution to whichever disappointment you experienced is going to the 275gr monolithic bullet, you may be going in the opposite direction and would be better served by the 200gr monolithic bullet. So, do elaborate on the terminal performance that you're working to correct.
I also reload for a 6.5g AR upper. With a quality barrel and careful load workup, you can get them to shoot 5-shot 100yd groups that can be covered by a dime, off a BR setup. There are a plethora of powders that work well in the 6.5g. My favorite is AR Comp as it has 15 fps variation from -20 to +140F. If you work up loads in the late spring and summer, then hunt in the deep cold of winter, that matters. In either caliber I recommend the Rem 7 1/2 primers, but to be honest, I've never tried CCI 400's. I've got a lot of load workup Range Reports up on the 65grendel forum under the same handle.

The 200 XPB is a nice bullet too, but has a higher expansion velocity, so it has a much shorter range limit. I haven't had much of an issue with blood trail using the 275 TSX or the 200 XPB, though the animals don't make it far anyway.
Like you pointed out the 275 TSX only has 2 grooves, but if you window a mag, you can seat them out to catch the first groove. Ends up at around 2.33-2.34". You'll have to verify that your chambers can load that long, but they should. I've only loaded them like that and have never had an issue. Also, getting them to match the ballistics of Hornady factory ammo is done pretty easily, just be careful to watch everything while doing work up.
