Thread: ADI book max’s

How lenient are book Max loads ? How longs a piece of string I guess. So I’m trying to get as much speed as possible out of my .223. I’m using the 69gn targex and have just switched powder to 2208 for more speed.
Book max states 26.0 which is a compressed load. I’ve gone to 26.5 with slightly flattened primers but no marks. I’m using new Norma brass. The rifle is a T3x with a 16”5 inch barrel. Looking at the load data 2208 should be the fastest. Worth trying anything else ?
Any ideas or input appreciated.
