I'd zero the rifle at 50 or 100 with which ever type of .223 you're going to be using in it, then find where it impacts with the .22lr.

I already have an AR set to 100yard with a 4x scope, so yes I know I can dial that to other ranges. However, I am trying to set up another with an EOtech that I will only use for close up, a dedicated setup that will not be used beyond 20 odd yards.
Report
This is the result:
(1) Put in a .22 conversion kit.
(2) Sight in from 25yd using EOTech.
(3) Play around with various drills from 25yd down to 5yd.
(4) Swap back in the .223 BCG.
(5) Repeat step (3) but with .223 rounds.
Findings:
(6) No discernible/significant POI differences between .22lr (step 3) and .223Rem (step 5) for CQB purposes.
(7) But significant practice differences for follow-up shots and hence rapid strings as well, obviously due to recoil differences.
Recommendation for self (Might seem obvious, but I wanted to try first hand):
(8) OK to do this for <25yd CQB sight in of a x1 red-dot if a range does not allow up close centre-fire rifles at pistol ranges.
(9) Good enough to practice deliberate/slow or single-shot-snap or various positions CQB drills using .22lr.
(10) Not good enough to practice follow-up shots and rapid strings.
Cheers.

I would disagree with points 7, 9, and 10. I cannot afford to shoot 300-400 rounds of .223 on my own time every range visit. Since getting my Spike's Tactical kit and putting more than 5000 rounds through her I have found my shooting has vastly improved; such as trigger control and shooting faster under control since I find .223 doesn't have much more recoil than .223 fired through a semi-auto.
I'll even fire 3-5 rounds and then do a tac reload before shooting again which has helped as well.
The only drawback to .22 is not being able to practice other stoppages and the bolt does not lock back when the magazine is ejected
Great input and feedback, thanks. Good to know your first hand experience.
I think you meant (7) and (10) right? I don't think you are disagreeing with (9) eh?
Cheers.
Nope! I disagree with point 9 as well. You said it was "good enough to practice deliberate/slow or single-shot-snap or various positions CQB drills using .22lr" which implies that is the upper limit or exent of it's usefulness in training which I disagree with.

Anyhoo, btw just curious how many rounds (approx) of .22lr in your AR before it gets dirty enough to cause FTF?
Cheers.
I oil up the kit (bolt and rails) and the underside of the charging handle (a lot) and can usually put at least 300 rounds through my kit (no stoppages) before I have to wipe it down and re-apply the oil. I'm using those cheap Winchester bulk packs from Walmart. I have the stainless steel Spike's Tactical kit. I cannot emphasize enough to use lots of oil. I tried CLP and that didn't work very well at all.
Sometimes the chamber adaptor on the kit gets a little dirty with built up carbon. I'll put a .22 bore brush and cleaning rod on my drill and clean it out (done it twice so far) after applying some CLP and letting it sit for awhile.
I too find it gets quite yucky after only a few hundred rounds (a lot faster than .223), and needs quick wipe down then. But like you said for close up practice will definitely save money. That's why I decided to get a dedicated AR+red dot to use with .22lr conversion kit. Save some money in the long run so I can practice 100m to 500m with .223 on another AR with a x4 scope on.
