Load data for 6.5 SST II. Ran 140 Bergers with 61g H1000 at 3201. ES at 21. Temp 56, Elevation 5702 and it shot a nice group. My BTO is 2.150 since I am running a magazine feed for this build. Max COL is 2.860 with the HS Precision mag. Wyatts will give you 2.880 with a slight mod to the magazine. This is what works for my build. Just info for fellow 6.5 SST shooters. I am running a 26" wilson barrel, 8 twist, #4 contour with a MBM super babybeast brake. I have load data for the 30 Sheman mag as well. Just finished cerakoting the 28 Sherman Mag today so out for testing this week. Best of luck to all.
