Come on, The 280 AI and the 7 Rm are both great. They both have there pros and cons.

The 7 Rm can be pushed faster.

The 280 AI is more efficent.

The 280 AI is not belted. A plus to some. Brass WILL last longer in the 280AI.

I have a 280 AI and it is fantastic. I built it to shoot longe range. And I love it. I also have a 7 RM that is a lightweight, It is a good gun built for two entirely diffrent purposes.

If I had to pick one. Hands down the 280 AI is the winner.And lets not forget this catridge does not need fireforming anymore. Both cartrides will be around for ever.
