I have the same barrel ...BCA 18 s/s fluted and I had put about 400 rounds through it. It hated the Hornady sst but would shoot the Eld-m good(around 1 moa )but the Hornady American gunner 123 (bulk 200 case) Was a little bit better ..... BUT ... it would only do this for 20 rounds at a time. Didnt matter how long you waited between shot. Shoot 4 5 shot groups and then it would go to around 3-4 moa groups. If you was just hunting with this gun it would work great !!!! I could always hit exactly were I wanted to with a cold bore shot ..... just not shooting over and over. I still have it but also bought a different upper that has a Faxon match series barrel. It shoots about the same but doesnt change after it gets hot. Good luck
