Shot a 222 Rem years ago and as I recall there were .223" bullet's designed for the Hornet. Never tried them in 222. Seems they were either 40gr or 45 gr, maybe both.
Some of those are .223, not .224. I’m shooting up the older .223’s, fireforming Hornet to K-Hornet.
Don’t think the .223’s will be that accurate in a .224 bore. I’ll know pretty soon.
