If yer gonna shoot 140s, ya need a 280: Care to share why you think you need a 280 to shoot 140s? It was a funny.  Everyone KNOWS the 280 is FAR superior to the 270’ right?.

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.

Not to mention the superior case design of the 280. The longer neck may contribute as many as five additional shots before the barrel goes South.
338 vs 270 ? This would be a good combo in Africa or Alaska but otherwise how did this come up?

My 280AI doesn't gain enough to make it worth forming cases, cool round though.
