I could use 48.1 grains of H 414. That would push me to 2800 fps. According to the book, that would give me in excess of 2000 foot pounds of energy at 100 yards!
Fred, you're looking at the Hornady
rifle data developed in a 24" barrel. According to Hornady's own data, expect to loose 300 fps going from their 24" rifle barrel to the 15" Encore barrel. I can't find any current loading data giving more than 2600 fps to 139/140-grain bullets with the 7-08 in 14-15" barrels. But don't dispair, I know from experience that a 140/150-grain bullet exiting at 2400 fps is plenty for any deer out to at least 250 yards. This cartridge is ample for the task.
BTW, 250 yards is a
long way when shooting
in the field with a handgun, and because it can be very tough to estimate ranges, many of the "250-yard" shots reported are actually closer to 150. Unless the hunter uses a laser or can pace out his distance on
flat ground, hold many of those long shot stories with a grain of salt.....
