[QUOTE="AZShooter, post: 755350, member: 5219"] JE Custom, Interesting discussion. I am wondering what ballistic program and elevation you are using to support your claim? "Thats the case with all of the 300 grain bullets. They will all drop below the recomended velocity at 1300 to 1500 yards." I used the JBM program with 7500 ft as that the minimal elevation where I have hunted elk over the last 25 yrs. Every elk I have ever shot at was found at least 7500 ft elevation with some close to 10,000 ft. My JBM program, with the approximate velocity of a 338 Lapua, at 2800 fps with the theoretical BC of .720 for the 300 gr Accubond shows the bullet to be going 1300 fps at just over 2500 yds with 1500 ft/lb right around 2050 yds. This is much farther than you are suggesting. The 300 gr Berger hybrid BC of .818 performs even better. It is slowing down below the minimum velocity of 1300 fps at 2800 yds with 1500 ft/lb of energy just past 2350 yds I might be off slightly due to temperature/humidity input variances. It would appear that either 300 gr bullet shot from a 338 Lapua at 2800 fps will perform to your standards at distances well past your suggestions. IMO this places the .338 300 gr bullet as very suitable with the 338 Lapua for very long shots on elk. [/QUOTE]
