H110 is a unique beast. It's likely well below max in Indymadcaster's gun - I've known people who are running charges of H110 3-4 grains over published max with no pressure signs. I've had a very hard time getting .44 mag rifles to show any signs of pressure. Pistols, where Hodgdon's data was likely developed are an entirely different ballgame.
Hornady 8 lists the 240gr XTP as 24.8 grains max load with H110 and a WLP primer. This load was developed in a pressure barrel and verified for safety in an 18" Ruger Carbine H110 is a powder that you can only reduce about 5% before it becomes unsafe and goes off on pressure excursions of epic proportions.
Obviously, cross reference every single bit of data you read on the internet, but Indymadcaster's load didn't raise any red flags to me.
