Care to share why you think you need a 280 to shoot 140s?


It was a funny. smirk

Everyone KNOWS the 280 is FAR superior to the 270’ right?.


Well I guess... Missing sarcasm, maybe.

Using a 140 grain NAB in a 270 gives a slightly superior BC than the same 140 in 7mm. Velocity with maximum loads is ~3000 fps, with neither being 100 fps better than the other. If anything, I've been able to get a little more from the 270 given equal barrel lengths. So, virtual twins the way I see it with 140s.
