If I ever build one, it's gonna get a steady diet of the 150 NBT with enough powder to get it to 3,000 fps. I'll stop there and try to go fill an ark...
Old thread but what the heck, I enjoyed seeing Bob's posts again.
In mine, both I-7828 and R-26 get me to 3050 with 150 NBTs, with good accuracy out of a 24" barrel.
