The 280AI is another good way to start 130-140 gr bullets at 3100-3200 fps.With 150 gr bullets it's about 100 fps faster than a 270 Winchester with the same bullet weights.

For the heavy bullets of 160 gr and up,the 7 Rem mag is a slightly better mousetrap.

In other words, it's a good cartridge and suited for the same animals as a 270,280,7x57,7/08,7mm WSM, and 7 mag,and will kill lots of stuff.

To my mind this is a case of the rifle making the caliber....the Kimber 84L or Montana (like the 7mmWSM in the Montana)is a unique piece of gear among factory offerings, chambered in 280AI. Lightweight,near 7 mag performance, handsome and with great ergos,and M70-like in function.

If building on available actions,I'd rather have the additional case capacity of the 7 Rem mag over the 280AI.There will be no difference in action length,rifle weight,or barrel length,and the greater capacity of the 7 RM makes it more versatile with heavy bullets.

The 280 Remington is overbore.

The 7 Rem Mag is over bore.
