After I used the 140 Accubond in my 270 WSM I don't miss the 130 option.
The 140s are very flat shooting because of the high BC. I think the 140s are great bullets for .277 - standard or mag
I have been usung the 140 Accubond in my 270WSM. Accuracy has been as good as BTs. I used the Accubond on a pronghorn with excellent results. At the shot the Buck was down and dead with a heart - lung shot. I think you would be happy with the Accubond.
