I went with the 284 Win just cause I like to be different and we had the reamer. With the 162 A-Max my COL is 3.100" .010 off the lands and it seems to be working great. The 280 is a fabulous round and what this rifle was going to be until we found that 284 Win reamer :-) I have been told by several that my velocities are not correct and I must be overpressuring the case and I'm not going to doubt anyone but I show no pressure signs and am on the 5th loading with this brass, the 162's across my CED are clocking 3011fps, I upset some buddies with the 7WM not getting there.
I think the 280 AI is a good round and have known of 2 but they had issues with accuarcy and went back to the straight 280 and fixed the problem, why an issue I couldn't tell ya. You could have issues if you wanted a repeater with the 280 and 180's
I am loving what my 284 is doing for me and it is my only strickly hunting rifle I own! I have several others but they are a touch on the heavy side so I built the 284 with a pencil barrel at 26" being I mostly hunt out West I like the added range. I think either way you go 284 or 280 you should be a happy camper but my nod would be for the 284 and seat the bullets out further. Later,
Kirk
