Report Disappointed with 5.45 x 39 energy transfer in General Discussion - Any topic is welcome here!!! Posted April 29, 2013 Part of being a gun owner, you should be informed. If you've looked at any ballistics data of the 7N6, you'll see that it won't tumble until about 2". Do you expected to encounter home invaders no thicker than a tube of caulk? Also, you can feed it Hornady V-Max or some SP. Regardless of what firearm you'll use for SD, would you really want FMJ for in the house? The answer is no. For a quick review of Wolf SP: http://www.akfiles.com/forums/showthread.php?t=136964&highlight=wolf+5.45x39 If you say "But I can't find VMax or Wolf". Understood. Ammo is hard to find right now. I bought what I have pre-panic and though I have plenty of 7n6 and Wolf SP, I'm stingy on the VMax. Luckily for practice, the VMax shoots same POI as 7N6 for my rifle, and VMax is my round of choice for 5.45x39 home defense.
