uk r h: don't have it for the PSP, but I do have it for the Hornady BTSP. Since you need a start charge, it should work fine. 40.0 grs. H-450 Vel: 2739 FPS @ 40,300 CUP. Max load is 46.5 grs. H-450 Vel: 3032 FPS @ 51,900 CUP. WARNING In PSI, that would be just under 62,000 PSI and in recent years, SAAMI has reduced the Maximum Average Pressure of the .243 Win. to 60,000 PSI. This load is from the Lyman 46th edition and the data was a little warmer then.
