If you can find data for that obscure cartridge in other places, your lament might make sense. Not likely anyone here is going to the expense of having a pressure barrel (where would they even find a reamer?) made and data developed for the perhaps two people in America that have rifles so chambered. Not even the Hornady manual covers that one, and they've got stuff I've not seen elsewhere. Nosler doesn't list 7977 for either of your "bracket" rounds. Perhaps there's a reason. Certainly you didn't buy powder for which you had no data.
Try Norma.
P.S. Hodgdon does list some data for the .26 Nosler and 7977, but only with 100 and 120gr bullets.
