I have one that was put together from a Mossberg 1500 action (might be the best trigger I have ever shot) and stock and a rechambered Rem SPS 7mm-08 barrel. Bought a set of new dies and 100pcs of Nosler brass. Had all the metal dura-coated this summer to a flat black. Planning on sending it to have it pillar and epoxy bedded this winter. When I get it back I will do some load development and hopefully it shoots well.
Wish I could find a detachable mag system for it, but no luck so far.
The 280AI?...it's pure magic...how else can a cartridge with about 10 grs less powder capacity run as fast or faster than the 7 Rem Mag...gotta be magic.
It's simply a case of the factory 7mmremmag loads being very mild.
With proper handloads,the 7mmremmag does hold an advantage.
Or 7SAUM!With the one 24" 280AI that I played with a lot, reasonable handloads gave 3050 with 150's, 3160+ with 140's, and 3370 with 120's.
Plenty of velocity but it's no 7mag loaded to the same pressures. Not directed at you Stubble, just sayin.
The 280AI is a neat cartridge. Probably just as good as 270, 280 or 7mag!![]()

My own 280AIs produce 3140fps with the 140gr TTSX out of 24" barrels.
As I previously posted.
All sounds great to me! Just made a deal with Clay for the new Cooper .280AI. Going to be exciting to work up a load for that one, can't wait.
That'll be a nice one....you can get 280AI brass from Nosler...no fireforming...
I do plan to try a Cooper someday...maybe if I can move some of my old Model 70's and a few 700's outta here I'll have room for a Cooper.
By "room" you must mean cashCoopers cost as much as a few of each combined!
a Cooper is about $2000-$2500.
How consistent is that 280AI Nosler brass?
