.240 Cobra (P.O. Ackley Data)

.240 Cobra (P.O. Ackley Data)
Warning! Notes: Standard twist: 12". The 240 cases are made by necking the .220 Swift cases up to 6mm and fire forming them to final shape. This cartridge has almost ideal capacity for the 6mm bore and produces relatively high velocity with good barrel life. Being a semi-rimmed case, it requires some magazine alteration on standard bolt actions to make it feed reliably. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION
