I'm familiar with the differences in the chambers. I was just curious which spec Savage used and expected it to be the SAAMI .223 Rem. I was just curious as I've worked up handloadsd for my AR's using Ramshot's (and Barnes&#39 5.56 pressure data, not .223 Rem (there's a significant difference). Regardless of what is claimed by Savage I still intend to start over with this rifle but was curious what to expect.

According to package tracking the rifle is being delivered today so I'll know more very soon.
