[50cal Smokepole]

I tried reloading some .223 brass (after firing from the 5.56 chamber) but it didn't group as well the NATO brass. Still, having the option is much better than not having it. I'll gladly use .223 to take out zombies at 50 yards, where the accuracy difference doesn’t amount to much.

I agree, and was also aware of the accuracy issue. I bought this weapon for a training class in order to be comfortable and capable of “running the gun” should a serious situation arise.
