While you are certainly entitled to propel a 3/4 oz load at any velocity you wish, it doesn't mean it's a practical idea.
I used 16.1 grs. of Clay Dot for about 1150 fps. and broke any clay that I led properly.
Maj. Burrard proved long ago that high velocity - like 1500+ fps - is reduced to standard velocities in surprisingly short distances. Thus, you burn unnecessary powder and get unnecessary recoil for little or no gain. Then again, perhaps BPI has found a way around practical physics. Ask them what their 20 yd. velocity is.
