I bought some Federal Hi-Shok 150 gr factory loads to use this season. The buzz is Federal replaced this design with one that is cheaper to produce, but the Hi-Shok design works very well.
We will see.
I have been shooting 150 gr Red Box Fede3ral as practice ammo out to 400 yards, and it works well. I am thinking that the Hi-Shok at 300 yds and under will be a good deer load.
