Perhaps I am wrong on this, though this is where my gut, & my 45 years of reloading is pulling me. Not quite enough steam in the boiler room for this one.You may be right BUT I'm new and having seen on paper that the 101 at 2800fps gives better or the same downrange energy that the 87 or 90gr does at 3000fps + I would like to put hands on
Are the 95 grain plus offerings worth a try? By all means give it a try & report back. Though the 101 gr hammers recommend a 7 twist. The 7.5 twist of our 6mm ARC will fall a bit short if you have a standard twist.
I had picked up some 70 hammer hunters & 83 grain shock hammers in the past. Expect I'll roll with one of these this season.
Take one with my OAL gauge and see how it all fits together, how far into the case it fits and what I can do with different powder
I did go to the twist cal. you mentioned and it is within specs so we'll see
