What is the affective range of a 223/5.56x45 bolt action rifle?

I shot this 5-round group with an old Remington 700 BDL Varminter from prone using only a Harris Bi-pod and an improvised sandbag for the buttstock. This was a personal best for this rifle.
As for the effective range...Effective on what?
I know guys who kill prarie dogs with this cartridge out to 1000 yards...and coyotes out past 400. As for effectiveness well that is a very subjective question.

This is a 700 PSS in .223 1/9 cut down to 20". It will easily make fist sized groups with 69gr bullets out to 500 on steel silhouettes all day long if you can read the wind a bit. If it had a faster twist I would shoot some 77's in it and push it out much further.

I know jack about .223 bolt guns. Do they make one in 1/7?

You'll be hard pressed to find a factory .223 bolt gun with a good twist rate for stabilizing the heavier bullets. I think the Tikka's come in 8 twist, but that's all I can think of off of the top of my head. Remington would have had a winner with the new 5R, but they set the twist rate a 1-9, which makes little sense to me.

I'm having a 223ai built with an 8 twist Rock, specifically for flinging the 75gr amaxes out to 1k.

My NRA "Service Rifle" has a 1/7.7 Kreiger and it shoots the 77's nike there is no tomorrow. When I shoot this barrel out I will buy a Kreiger with the Remington PSS contour for it. As it is, I use 24g of Varget and Nosler 69's. The barrel is free floated and it has pillars torqued at 65"lbs. It will give me groups of just over 1/4" at 100 on a very regular basis.

I agree, if the .223 Remington 700 came in a 1/8 or 1/7 it would be a very big hit.

Let's be honest, a 223 bolt gun is just a fun rifle to shoot all day long.

There are a few 1in 7's around. Including Savage.
1 in 8 should be ok for many of the heavy (but not 80+) match bullets which would be used for longer ranges. (watch out if you buy S/H as some of the older Tikka's and others changed twist. 1 in 8 now, used to be 1 in 12)

.223 and .308 are about the same with target style loads for trajectory. .223's might be a bit harder to shoot over the longer ranges. 500mtrs is easy, 800 is ok and with practise 1k is fine. You DO need to watch out for some of the guys pushing really heavy reload data to do it. You only need to have a safe margin above supersonic. You gain very little from the much heavier loads and end up taking a risk, expect issues on hot days and short brass life.

For "serious" use your limit is probably going to be which load you use. The best terminal performance is likely to come with a load that has a shorter accurate range.
