My Superlight .223 likes 25gr. H4895 behind the 53 gr. TSX. The first two shots will land within an inch of one another @ 100 yards and, more importantly, consistently to point of aim. The third shot opens the group up to about 2". (The Superlight barrel has a 12" twist).
I use the same powder/charge behind the Nosler 60 gr. Partition. It shoots to the same point of aim and the same accuracy. It's another option.
