    I think ya' 'max out' with the 6mmA.I. for a 6mm/.243 round. After that, you're just adding more and more propellant for less and less gain in velocity.

    I you just want a fast shooting 6mm, look at 240 Wby. It responds well to handloads and factory ammo is available.

    But, like Ron said, ...long action/magnum bolt face, or single shot.

    I have both the 6mm Rem and 6mm/284. I don't really notice much difference between the two out to about 400. Past this the 6mm/284 starts to get noticeably easier to hit with. My 6mm/284 is built on an action that was originally a .243 win and will not feed from the magazine reliably. If I make another 6mm rifle it will be a 6mm Rem Ackley Improved. Probably the best of both worlds.

    I should have said I am thinking of rechambering my 6mm to a 6mm-284 or a .240 Gibbs I already have a 6mm Ack imp . Too much work going to a .240 wby mag.

    I have both the 6mmAI & The 6/284 & love them both, 6mmAI 1-12 twist 87grn V-Max @ 3500fps & the 6/284 1-8 twist 107 smk @ just over 3200. Both shoot lights out & both have their specific uses.

    If you BEHAVE yourself :D the 6/284 will treat you very well; & if you don't, expect to have your bbl set back pretty dern quickly! I 'ersonally wouldn't recommend the WBY, I am kinda biased when it comes to that so I won't stand on a soap box here. Velocity potental is very close between the two although the 6/284 has a good bit more availability in the brass area.
