I actually use a program to calculate the MV from instrumental velocity. However, if you look on page 386 of Lyman's 48th Edition, you'll find a BC of .213 for the 358156. On page 338, the 358477 has a BC of .286. A little heavier bullet, the 358429, has a BC of .286.

So, if we just use a BC of .2 the 1077 fps instrumental becomes 1104 MV. Since I only came up with 1102 fps MV, I must have used a lower BC than .2.

The program is called "Remington Shoot!", which is a free program, which is available here: Remington Shoot Ballistics Software
