Sumatra has power to spare so I would try those 25 grain and 34 grain JSBs. Good BC equals reduced wind drift.

It rests entirely on the initial velocity to be fair, 18.3 in no wind at all and at the right velocity will generally have the edge, but introduce wind and the 25g JSB RD MONSTERS will have it every time, the 34g BEAST never seems to be as good at 100 yards as the 25g no matter what velocity.
If you can push the 25g RD MONSTER to 1000FPS even better but they need around 930-940 as a minimum, below that velocity and after 75 yards they aren't as good.
My Bsa superten runs at 38 ft lb , and loves 18 grn Diablo field heavies
