[QUOTE="Deleted member 46119, post: 1027986"] You are correct about the moderate pressures. Retumbo can be loaded compressed and I don't see a way to go beyond safe pressures. There is a book load that is acceptable velocity. If your throat will allow it, longer COAL will get you more FPS. Burn profile gives you pretty good ballistic efficiency. If you have a 26" barrel then OBT gives you nodes at ~2620fps and ~2720fps, both fine for the Berger 230s If you have a 24" barrel then your OBT node is more like ~2600 or slower. All the best.
