both are equal. I know, no way the russian round is accurate as the 223, and mostly , with 99% of the ammo, you would be right. But the silver bear stuff;
lemme just say, wow!!! And it is not just my rifle, I have had 2 saigas in 762, and they both were like that, and other dudes who have used silver bear in their 762's, have been amazed. Oh yeah, make sure it is the hollow point stuff.
But generally speaking, yes the 223 stuff will be more accurate- and more
expensive.
