[QUOTE="CHARLIEDUECE65, post: 587720, member: 15083"] I have a 243 Winchester. I am shooting the 105 Amax with H4831sc powder and BR2 primer. Anyways, I printed out a drop chart based on the above load with GM210 primers I had chrono'd awhile ago. The drops aren't accurate at all. My 200 yard correction was 4 clicks at 1/4" click value on a leupold scope and the 300 was 10 clicks total. The sierra data says 5.3 at 200 and 13.4 at 300. Is this normal? I tried to adjust the velocity higher on the sierra load data to see if I could match the real world data but couldn't. I see the 200 yard data is fairly close but when you get to 300 its starting to get aways off and will probably be even more the further out I shoot. Is there a more accurate program or is it me?
