30 ish is more reasonable and prety common.
13:1 gears and m110 or 120 and a high torque motor should net you 28-33 bb's/s and a snappy trigger response. Otherwise you'll want lower fps or a DSG, short stroke, bore up, and a heavy ass spring to hit 60rps and 400fps and be reliable and not set shit on fire from heat lol
Edit. You are gonna want a good piston and head and cylinder and head and such as well.
