Almost any of the 17's will do it, although 30 grains is at the top of their weight slot. Then there are the 19s and 20s. All of them will do almost that fast with 40 grainers, so 30s should be easy.
When you get to .22-cal, the problem is that a 30 grain bullet is much too short and stubby to hold velocity. But 3800 fps is not out of reach with a sleek 40 grainer.
The 20-cal round I'm testing now spits a 40 at 4100+ with less than 35 grains of powder.
