I am a big believer in having all of my hunting rifles zeroed exactly the same. 3.5" high at 100 yards, then shoot it out to 600 yards to develop your drop tables. Majority of hunting shots are under 300 yards with the odd one out to 500. This means most of my guns all shoot pretty much the same to 350 yards.
Shooting targets at long range is fun but on game, I will stalk to within no more than 400 yards if at all possible. This makes a 300 yard zero with my 7 RUM, or in your case 28 Nosler, basically point and shoot to 400. Don't have to start twisting or using holdovers till you get further out. If you regularly hunt at over 400 yards with very few closer shots and have to twist knobs anyhow the zero distance isn't as important, but again I would have all my guns set to the same 100 yard POI.
