223, 223 Ai, 22-250 or 22 creedmoor??

204-224 would make up for any loss of speed when shooting 75’s and 88’s. Now that I would be for. So really just a 222 magnum eh? Haha

All good options depending on what you want to use as the base case... meaning brass.

With the widespread popularity of 223 including once fired military brass, the 223 AI has the convenience edge going for it.

On the negative side is the basic need for fire forming AI.

Like I said earlier... it would be nice if demand was more widespread. Consider how the 6 Dasher had to be fire formed and now due to popular demand we can buy new brass for the Dasher.

The older I get, the less forming I like to do..

not sure if the 22cal will pick up in popularity in the US PRS family? Likely it will be with BR's and dashers since it is just a rebarrel for many... time will tell.

run 204 Ruger brass through a 22cal expander mandrel... done.. if you are making the wildcat and making your own reamer. That is if you want the 22-204 Ruger...

if you just want a 222 Rem mag, that is factory off the shelf stuff. Brass is harder to find but possible... or you can make from 204 ruger by running through a FL sizing die

Personally, that is a lot of expense for a limited case volume. I am very happy with my 22 Creedmoor.

Berger just announced a new high BC .22 projectile offering, a 85.5 grain hybrid.

Another great option for those looking for a high BC .22 projectile. This would probably be my go-to choice, as Berger's have produced excellent results for me from 6mm to .30 Cal.

Certainly makes the prospect of a centerfire .22 more appealing.

I'm running the Hornady 88 grain ELD match and they claim a G1 BC of 0.545, and this Berger is close at 0.524. I'd be interested to see how they group by comparison to see if the accuracy offsets the slightly lower BC.

So far the 88s have been pretty fair for me with most groups around 1/2 MOA at 100 yards, but once in a while I get a shot off that seems to have a mind of it's own and for no rational reason opens up a group to just under an inch. I don't get that with 80 grain SMKs and they group better than the 88s all the time. They just don't have anywhere near the BC.

I'll have to get a box of these 85s and see what's what.

In regards to simplicity, .223 for sure. Most good components readily available off the shelf. Great barrel life. To me the gain of the 223 AI not worth it. The later 2, 22-250 or Creedmore, barrel BURNERS. If money no object for barrel replacements do whatever you want.
 
I’m having a second 223 rifle built but this time I’m contemplating trying a 223 ai for the extra velocity for the 75 eldm bullets. Plus no case trimming apparently. I was gonna do a 22-250 fast twist but I want a more efficient cartridge

I wouldn’t put a ton of money on big velocity gains with a .223AI. There is certainly some to be had, just not as much as some would have you believe. I absolutely detest trimming, so I love mine because there is no growth. For training & coyotes, it’s pretty damn hard to beat the .223 AI. A fast twist 22-250 would be great & there’s not an objectionable thing about it, but unless you’re frequently going beyond 600m, I can’t see much advantage other than getting there quicker & cheating the wind a bit. That is more than enough justification for some, & is a great argument. I’m just perfectly okay with what I have - keeps me on my toes.

I say do your .223 AI. Then you can see the differences first hand. Then after several hundred handloads, you can sell your conventional.223 & build a proper 6BRA;)
 
Well my bighorn tl3 is a 223 rem match chamber. If I go 223 ai for the next one I could always get a different bolt head for my bighorn 223 and turn it into something else
