Thread: Lower than expected velocities

Cases could be a factor?
A bigger volume case could suck up a couple of grains of powder compared to another case.
GPmac have you and others suggested though that in the absence of sometimes erroneous pressure signs it more to do with the velocity as yiu can't have the velocity without pressure?
Stand corrected if I've got that wrong as I don't do bugger all reloading and have only just bought a chronagraph
