Try adi 2209/H4350 with the 310gn Woodleigh RNSP
I use an 600mm or 2 ft drop tube to load 63gn of the above powder and get 2,455fps at what appears safe pressure in my rifle with a 25 inch barrel 1 in 12 twist.
62 gn of the s a me powder gives me 2,340 fps
These loads are safe in my rifle only.

If you don't use the drop tube you will get 60gn of 2209/H4350 and very compressed. The drop tube allows more powder and minimal powder compression
