Until yesterday I was sure that the longer the barrel the greater the velocity for a given powder/bullet combination. However talking to an RFD yesterday he said this was not the case (specifically about a 17 HMR). His reasoning being that the modern powders have all burnt within a short distance from the chamber. Is he correct ?
