On Winchester's web site it lists 44 mag Q4240 (240gr semi-jacketed soft point) at 1180fps and energy at 742ft/lbs. However, I chronoed 6 shots of the stuff and got an average velocity of 1,339 fps with a high of 1360 and a low of 1309. That puts the energy at 955ft lbs. Has anyone else clocked this stuff? (I'm concerned about readings I'm getting with my son's chronograph while I'm working up loads. If the chrony is right winchester is playing down their loading.)
