Show Ws field guns and their effect if you yon insist on high velocity you hav to add so BO much additional machinery ma canery to your gun carriage and have to so greatly strengthen Us its construction that you yon detroy destroy its mobility while een if you gain a 1 long 19 9 range you are stilt still unable to malce make uso use of your most efficient projectile at it moreover since the remaining velocity of its shrapnel el is a truer timer measure of the value of a gun than it initial velocity and the two are by no means directly proportional proportion 21 it does not follow that we benefit as much as wp we might expect by submitting to these disadvantages thus the 12 11 has an initial velocity of over 1700 fert feet per second and a remaining velocity a at yards of sw feet while the 13 with an initial velocity 0 0 only 1560 feet has at the same nine banff range 0 o a 3 remaining velocity greater by six eix feet per second than that of its ita rival one of our highest authorities on fiela art artillery Ulery has indeed recorded his hill ion that as regards the efficiency ot shrapnel we gain nothing by the increased muzzle velocity of the best field gun in europe at all practical ranges moreover it is the attempt to squeeze out the last few extra feet that does all the harm london saturday review |
