[QUOTE="jmden, post: 210261, member: 1742"] 1 in 10 will stabilize the 240 at 300RUM velocities. However, Sierra says to use 1 in 9 for the big 240. I'm shooting 104.5g US869 at 3K MV with the 240 resting on the lands. This is a cold weather load. At least 60F or below. 4-6 firings. Good luck. [/QUOTE]
