Based on their data on the website, they do have a full grain difference between the 5.56 and the .223 book max. Since my tikka chamber passed the go/no go gauges for 556 and it’s a European CIP gun, I should be good using 5.56 data right? This is a new one for me.24.5 works for a lot of guys. I had some cratering at that yesterday in a custom barrel, 85F ambient. Hogdgon book max is 23.7 I think.
