Ive had my .243LBC for a couple of months now and just took it out for its first long walk yesterday. I set my targets out to 550 yards. Using the suggested .500 g1 coefficient at 2650 fps, 550 was about 10 moa. But upon firing, i was 15 feet short of the target. I corrected it to 15.25 moa and was on target. This is a lot of correction. Even a 6.5 grendel has less than that. What kind of velocities should i expect with an 18" barrel with a 105 amax? Im using H4895 and Fiocchi x39 brass until i can get lapua. Could the reduced capacity of the former x39 brass be limiting my velocities? I should be closer to 2600 fps shouldnt i? Does an admin have a velocity chart that i could reference? Thanks in advance.

Have you tried any of the 95s yet? Ritch and GLshooter shoot the sierra match king and Berger 95s. From what I have read and my experience with my friends 243ai the 95s are balistically flatter less windage and more energy then the 105s. Sometimes velocity can trump higher bc. I think I would try some 95s eithor bergers or seirra match kings.

Out of there longer barrels I think they are getting 2900-3000.
