[QUOTE="J E Custom, post: 1913404, member: 2736"] I had a longer (30") barrel and got 3254 ft/sec with 67.5 grains of H 4831 and a 168 gr match king with the powder (4831) that Hodgdon had recovered from surplus 20 mm cartridges."Warning" this would be a very hot load for rifles that were not chambered correctly for high pressures and velocities. Even with today's powders I would not expect these velocities without excessive pressures. J E CUSTOM [/QUOTE]
