2.5" at 100 isn't acceptable for a modern rifle. Especially one with low recoil like a .223. My sks will do that shooting offhand. It will also do about that bagged, that's just as good as it will do 
My 25 would do inch'ish right out of the box, it just got a lot easier to do when I worked the trigger. That's bipod and prone and when I shot a lot more than I have the last couple years.
Want to borrow a vice? I have a cheapy I usually use when I'm zero'ing a scope and want to take as much me out of the shot as possible. Throw it on one of the concrete benches at the range and its as solid as I can make it short of buying a lead sled.
