.270 Durham Magnum (P.O. Ackley Data)

.270 Durham Magnum (P.O. Ackley Data)
Warning! Notes: Standard twist: 10". Special twist: 12". The .270 Durham Magnum is a slight departure from the normal Durham design in that it has slightly more body taper, but the same sharp shoulder. These loads were developed in a 22 inch barrel with 10 inch twist and are considered maximum and should be approached with caution. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION
