280 rem in 280AI

I know you can shoot standard 280 rem's out of a 280AI, but curious about the downsides, if any. I am debating a 280 vs AI and want to understand what compromises I will have (if any) shooting a 280 rem out of an AI from time to time.

Is accuracy affected? I have read in some places that it is, but I trust the folks here more than any other site, and know that many folks have 280AI's here.

I have heard that velocity is impacted, but I want to make sure that the frame of reference is fully understood. Is it the obvious lower velocity of rem vs AI? Or is the comparison of a rem out of AI vs a rem out of a rem? I.e. will a 280 rem out of a 280AI have a lower velocity than a 280 rem load fired out of a 280 rem chamber, all else being equal?

Thx in advance.

    iam not 100 % sure on this but it would be my understanding you get lower velocity because the case size on the AI is bigger than a 280 rem

    Velocity will be slower because you'll be burning less powder.
    You may or may not have accuracy loss. It depends on the harmonics of your barrel. I have seen standard rounds shoot very well out of AI barrels, and some not so much. What you will have is a POI change, sometimes dramatic.

    I think that the .280 AI is a great chambering. Nosler has factory loadings for it (i think) and if not you can run the standard .280 stuff through it in a pinch. It is definatley in the running for the most efficient way to get a 180 grain .284 bullet around that 3000 fps mark and it feeds like butter.

    You would basically be fire forming the .280's into a AI. But with my experience and understandings of fire forming is not to use full weight charges. The .280 AI is a bad ass round.

    you better do some more research about shooting the standard rounds in the AI chamber

    Guys shoot factory ammo to fire form brass for AI's. I would bet that handloads where the bullet is seated so its into the lands will be accurate, but slower, as some of the energy is going into forming the brass, and not pushing the bullet out the barrel. Looking at getting a 280 and then reaming it to a AI. From what I've read the Nosler is differant than the original AI. Still trying to decide which to do.

    Re: 280 rem in 280AI

    The 280AI is probably my favorite rifle in my herd. Mine shoots the exact same between REM and Ackley except for velocity, it shoots in the low .3s with both loads. Im shooting full charge REM loads to fireform and have not had any problems. Im pushing 140 gr VLDs around 3150 with RL22 for my best acurracy, although Im about to start trying some 168s.

    My next build is going to be a custom .280 AI off a trued & blueprinted 700 action.
