I haven't found a bpi load yet that was accurate.
Loaded and tested one yesterday.
Fed hull
209A
Tc20
21gr longshot
1oz lead
1240fps
9200psi
I loaded it with ched primer and started at 20gr to be safer. It chronod at 1390 and locked the bolt back. Recoil was insane and the hull flew a good 15 feet.
I cannot stand BPI data
