I read an old post about this round. Lots of haters chimed in about how stupid of an idea it was because of its negligible improvement over the 223AI, 204 brass availability etc. I’m playing with the idea of converting a 1:8” Tikka 223 over to AICS mags and rechambering (If I can’t get it to do what I want in 223). Mostly interested in shooting 75 and 80 grain bullets. I guess there was an article about it in one of the gun rags several years ago. If anyone has a copy of that issue (Shooting Times, I think), I would be happy to pay for a xerox copy of that article. PTG and a gun writer supposedly came up with it. I’d also love to hear of anyone’s experience with this round. It seems to only have about 0.093’ more space at the top of the case body than the 223AI, which ain’t much, for sure, but I still might like to try it out. I’m just be irrational like that.
