[QUOTE="jeffro, post: 452338, member: 6780"] I chronyed my load on a very overcast day. The vel came out to 2795fps 300SMK. ES 8 fps 50deg F Groups at 100yrds were .260-.320 I put the data into the balistic program, and shot at 1000yrds. groups were 4.7in, and the groups centers were 2 in low. Not too bad, and I guess the data I got is quite accurate. I was just trying to figure out why the vel has dropped from where it was when the barrel was brand new. Its probably the chrony data from very bright days. The barrel now has 70rnds through it. [/QUOTE]
