.348 Ackley Improved (P.O. Ackley Data)

.348 Ackley Improved (P.O. Ackley Data)
Warning! Notes: Standard twist: 12". The .348 Improved was developed upon request of many shooters owning Model 71 Winchester rifles. The original .348 cartridge was very poorly designed in a way mainly because it had such a steep body taper that the bolt thrust developed was much greater than it should be, and this bolt thrust undesirable as it is, is doubly so in lever actions. The "improved" .348 combines minimum body taper and sharp shoulder design and is capable of giving a noticeable increase over the factory round. (Handbook for Shooters & Reloaders/Vol. 1 - P.O. Ackley, 1962) NOTE: USE THIS DATA WITH EXTREME CAUTION
