[QUOTE="dok7mm, post: 2318291, member: 90080"] I'm shooting Retumbo in my .264 wm with 156 Berger & with HBN in .212 free bore. CBTO of 2.856 (.065" jump) and COAL of 3.563". Peterson brass. Lower node is 65.3 gr Retumbo (2,972 fps), ES-5, Sd-3.1 on 3 shots, grouping in low .2's. High node is 66.8 gr Retumbo (3,025 fps.), ES-16, SD-7.9, groups in low .4's. That data was 65-70 degrees, 28.24 actual pressure, 40% Humidity in 26" Bartlein. 67.5 grains of Retumbo was max charge and groups opened to 1.3" with 31 ES. [/QUOTE]
