If they would actually take a minute to look at published load data the would actually see that the .280 AI will use a few more grains powder and recoil more than the 7mm Rem Mag actually will.

I do not want to argue here because it's pointless but you are totally wrong. The water case capacity of the 7mm RM is about 95.3 grains vs. the 67.9 of the .280 R, that's a huge difference, about 28% more capacity.
Old Roper said:When Nosler first started publishing data for the 280AI in 1996 they used a 24" long Wiseman barrel and top velocity with 160 was in the 2900fps and the loading data for the 7mag same bullet was in the 3100fps range and used over 10gr more power.
I've never build an Ackley based on comparing it to another case but I have build 7mag plus owned factory 7mag and have lot of loading data including chronograph results.
Taylorce1 does bring up some interesting points as to the 7mag and pressure. I think some of the data we load too is lawyer checks first vs other reasons like type of firearms used. Hodgdon manual does have lower pressure for the 7mag loads about 4KPSI than whats published for the 280AI. In some of the manuals I have from the 70's the 7mag 160gr bullet 3000/3100fps.
I considered the AI until my gunsmith advised trying a 280 with 26" barrel first. I could push 140s to 3150, 150s to 3000, and 160s to 2850 with RL-19 and IMR 4831. Not bad.
