I'm really liking the way Superformance is working out in my 300 WSM with 165 AccuBond, excellent velocity and tight groups to boot. My WSM is outrunning my 300WinMag with the 165's. Weight/caliber ratio is about the same as your 7/154. If you can get your hands on some, it might be worth your time and effort. Unfortunately I'm using the 190 VLD in mine for bear starting today so the 165 load I developed was a waste of time. If I choose to use it for deer, I just may drop down in weight and use the AB load.
