Brinky, my experience with N110 is the complete opposite of yours. I started out with 296, and could do no better than 3" groups at 50 yards.
With the N110, that shrunk to 1" groups. That was with a Beartooth bullet 300 grain, seated long, and with the Hornady 300 grain XTP, also seated long.
Perhaps H110/296 will be your friend. And, keep 4227 of both persuasions in mind, as well as AA#9. Those powders can run respectable speeds, and can be reduced. H110/296 is a high performance powder and doesn't like reduced loads much, as you are probably aware of.
I also use H110 and 300 gr. Beartooth WFNHCGC's bullets. I also get the same results and yes, they do like to pushed a bit. I used 2400 for several years with 240gr. bullets and liked them as well, but found H110 and the 300gr. bullets more geared towards my needs and/or intentions.
