Here's the data: 7mm Rem Mag, 180grn VLD's, 68gr H1000 Now, I dont own a chronograph, so I'm working with Berger's load data and trying to approximate my velocity. In order to achieve the desired energy on impact at 1000 yards, Exbal tells me I need to push this bullet at 2950 fps, so that is my goal. Here's what I'm working with and my thought process. Per Berger load data in a 24" barrel: 66 gr= 2830 62.5gr= 2672 Difference of 3.5 grains of powder and 158 fps. Simple math says that 45.143 fps increase with each grain of powder. Using the 66 grains= 2830 as a baseline, I added 90 fps for the 2 grain increase in charge and got 2920 fps. I also have a 26" barrel and figure that I gain about 50 fps over this data. Therefore, it is my opinion that I am close to where I need to be with this load, energy wise. Can ya'll confirm or deny this theory/ math for me? Thanks.
