[QUOTE="7magcreedmoor, post: 974138, member: 48559"] 67.6 grains of Retumbo over CCI BR2, 26" PacNor 3 groove 9 twist, 2905 fps. COAL wouldn't be meaningful as I measure and write my measurement using a comparator on the ogive, and I don't recall the dimension of the comp off the top of my head. Velocity derived by shooting 300, 600 and 1175 yards, then running the observed drops back through the ballistic calculator's trajectory validation tab. My COAL is longer than SAAMI spec for sure.
