3 grains lighter than an 80. I doubt it will be significantly faster.
Seems like kind of a bone head move. Why not a tipped 80 with an even better BC? If you want mag fed, why not a different weight to avoid confusion?
The 69 looks like it will save nearly 1/2 MOA of wind at 300yds, but still not equal to the 77 SMK. (According to JBM)
