So I've been shooting the Federal Power Shok 30-06 ammo I've picked up at Wal Mart in a blue box. It's been not quite a year since I got it. It says 3006A in the upper right hand corner on the end of the box. Like that's the model number or whatever. My rifle is very picky accuracy wise but it likes these and the Federal Fusions. They also both have the same POI at 100 yards and are both 150 grain. They have been out of stock for months now. Anyway, I finally found some instock now but it's in a red box. I bought several boxes and when I got home I noticed it now says WM3006A instead of just the 3006A. Is the WM in front of it to indicate it's for Wal Mart? It's also a red box instead of blue like it used to be. I know the only way to know for sure is to try it myself but in the meantime I was wondering if anyone else tried this stuff in the red box after having used the blue box stuff. Did it shoot the same poi? Did it shoot as tight of groups? Could you tell any difference?
