Does anyone know how the 6 inch and 4 inch models of the Webley MKVI .177 caliber pellet revolvers compare in accuracy and range? One reviewer found the 4 inch barrel model to have slightly greater muzzle velocity but less accuracy when compared to the 6. He seemed to know what he was doing and was even a bit more accurate with the short 2 inch barrel than the 4, but admitted that might be simply because it felt better in his hand. One person commented that greater muzzle velocity can cause turbulence at the muzzel that affects a pellet's attempt at straight flight. If so, is that an odd argument for slower projectiles?
