Those are impressive Daryl..thx for posting that...

I feel the same way, in the example of the 280AI, basically the same velocity as a 7mm REM, less recoil and a non-belted cartridge..whats not to like..

As to "Is it worth it" ??..Each to their own..but if one thinks about it, 3000 vs 3200fps difference between the 280 Rem and the 7mm REM mag..not quite a 7% increase for all that extra recoil and powder..based on that I can easily justify the AI..

Just trying to play devils advocate..but for me, as stated earlier, I like the different cartridges. They appeal to me more than the every day .270 or similar cartridges. As stated, thats just me..
